I updated Eclipse with the new SDK tools (rev. 23), but now when Eclipse starts I receive the error:
This Android SDK requires Android Developer Toolkit version 23.0.0 or above. Current version is 22.6.3.v201404151837-1123206. Please update ADT to the latest version.
No updates were found with "Check for updates". If I try "Install new software", I can see version 23, but I can't upgrade due to the following error:
Cannot complete the install because of a conflicting dependency.
Software being installed: Android Development Tools 23.0.0.1245622 (com.android.ide.eclipse.adt.feature.feature.group 23.0.0.1245622)

After download of the last ADT from the web site, it seems there's another problem.
With SDK Tools rev. 23 proguard is not installed, the folder SDK dir/tools/proguard is missing, and other tools are missing. This version contains several bugs.
Google has released ADT v23.0.2. This solved many problems of previous ADT version 23.
Step-by-step:
Menu Help → Install New Software...
For "Work with", select the Android source https://dl-ssl.google.com/android/eclipse
Tick ADT v23.0 for installation, then click "Next"
Eclipse will show "Install Remediation Page" since there is conflict with previous version. (If it does not, see below.) Select "Update my installation to be compatible with items being installed" to uninstall the old version and install the new one. After that, proceed with the usual steps.
Note: When I installed the new version of ADT, I didn't include the new version of "Android Native Development Tools" package. Instead, I installed the rest of packages first, and then installed "Android Native Development Tools". For a reason, if I try to install all the new packages including "Android Native Development Tools", the installation fails.
If there is no "Remediation page", the only way to remove the ADT plugin from Eclipse is to go to menu Help → About Eclipse → Installation Details and uninstall from there. But there is a risk of uninstalling Eclipse itself.
Google response:
This is a packaging bug. The entire proguard file is missing. We'll have an update asap, but until then just copy it over from a previous version of the tools:
http://dl.google.com/android/android-sdk_r22.6.2-linux.tgz
http://dl.google.com/android/android-sdk_r22.6.2-windows.zip
http://dl.google.com/android/android-sdk_r22.6.2-macosx.zip
and copy over the following files:
tools/hprof-conv
tools/support/annotations.jar
tools/proguard
So at the end if you started from a new ADT copy by hand the files :)
Edit: with the latest ADT release, the bundle should now work with auto-update, so install these new versions:
linux 64 bit vm: http://dl.google.com/android/adt/adt-bundle-linux-x86_64-20140702.zip
linux 32 bit vm: http://dl.google.com/android/adt/adt-bundle-linux-x86-20140702.zip
mac: http://dl.google.com/android/adt/adt-bundle-mac-x86_64-20140702.zip
win32: http://dl.google.com/android/adt/adt-bundle-windows-x86-20140702.zip
win64: http://dl.google.com/android/adt/adt-bundle-windows-x86_64-20140702.zip
Don't try to upgrade from previous version because it doesn’t work at all.
If you have got problems with zipalign, it's now under build-tools and no more under tools/ so you can do a symbolic link or just copy it into the expected folder.
None of the other answers worked for me using the ADT bundle published on developer.android.com.
I ended up downloading the latest version of Eclipse (not the ADT bundle) and then installing the ADT plugin via menu Help → Install new software → entering https://dl-ssl.google.com/android/eclipse (mentioned by #RED_).
I also had to update my workspace to point to my previous workspace, and most things seemed to be restored.
On a side note: This seems like a good time to migrate to Android Studio...
NOTE: Use this approach with caution because this might break your Eclipse installation (see comments).
This might help you if you installed the ADT plugin manually. But if you are using the version of Eclipse from the Eclipse ADT Bundle the below steps could break your Eclipse installation, and you may not be able to use Eclipse again!
Go to
Menu Help → About Eclipse SDK → Installation Details.
Now you will see all 22.0 versions and then click Uninstall button at bottom.
After uninstallation goto:
Menu Help → Install New Software → enter http://dl-ssl.google.com/android/eclipse/
Then install all the things, and now it is ready.
I was updating my build server today and came across the same issue. It has been reported here:
https://code.google.com/p/android/issues/detail?id=72419
The fix is in progress and the work around according to the project manager is:
Please wait for an updated version within a day or two. Until then, your workaround is to do download one of
http://dl.google.com/android/android-sdk_r22.6.2-linux.tgz
http://dl.google.com/android/android-sdk_r22.6.2-windows.zip
http://dl.google.com/android/android-sdk_r22.6.2-macosx.zip
and copy over the following files:
tools/hprof-conv
tools/support/annotations.jar
tools/proguard
[edit]
zipalign was missing for me too, check to see if you need to copy this as well
It works for me :)
If for some reason you installed an ADT preview and need to revert back to the current stable, you can't use the dialog to install "new" software since what you want is actually an older one. Instead do this:
Open Help > About Eclipse... on Windows or Linux. On Mac, use the app's menu > About...
Click the "Installation Details" button.
Select the "Installation History" tab.
Select one of the previous configurations.
Click the "Revert" button at the bottom.
is what they are saying about this:
OK, guys, sorry about all this trouble, and we apologize for the messed up releases. Here's the summary:
There is no way to update an existing ADT bundle that you might have downloaded.
You can do one of two options:
Install Eclipse from eclipse.org and install ADT by pointing to the update site: https://dl-ssl.google.com/android/eclipse
Download bundles from here:
Linux 64-bit VM: http://dl.google.com/android/adt/adt-bundle-linux-x86_64-20140702.zip
Linux 32-bit VM: http://dl.google.com/android/adt/adt-bundle-linux-x86-20140702.zip
Mac: http://dl.google.com/android/adt/adt-bundle-mac-x86_64-20140702.zip
Windows 32-bit: http://dl.google.com/android/adt/adt-bundle-windows-x86-20140702.zip
Windows 64-bit: http://dl.google.com/android/adt/adt-bundle-windows-x86_64-20140702.zip
Starting with ADT bundle 23.0.2, you should be able to update to future versions of ADT.
Source: https://code.google.com/p/android/issues/detail?id=72912
I have done following to resolve an issue.
Go to http://developer.android.com/sdk/installing/installing-adt.html and download the latest ADT ZIP file (at the bottom of page).
Go to Eclipse → menu Help → About Eclipse → Installation details
Delete Android DDM, Android Development Tools, Hierarchy Viewer, Native Development Tools, TraceView, etc., 22.X version.
Menu Help* → Install New Software → Add → Archive → *Select the downloaded ZIP file in step 1.
Select all the latest version of all 23 which I have deleted in step 3 and accept the license agreement.
Restart Eclipse, and it fixes my issue.
Only helped:
Fresh Eclipse installation (http://www.eclipse.org/downloads/packages/eclipse-ide-java-developers/lunar)
Help --> Install New Software --> https://dl-ssl.google.com/android/eclipse/
If you install a new Eclipse version it will work.
Here's what I did:
Installed the new Eclipse version, Luna
Made a backup of the current workspace.
Ran the new Eclipse, Luna, and updated the workspace
Installed the ADT plugin (Help -> Install New Software)
Restarted Eclipse
Done
There is a lot of confusion going around in this thread. There are two solutions depending on how you installed ADT.
If you installed the ADT plugin manually then I believe you can use the "Delete ADT" -> "Install New Software" approach.
If you are using the ADT Bundle then do not follow that solution! You will break Eclipse. Here is an update from a Google member - read #18:
https://code.google.com/p/android/issues/detail?id=72912
You must download a new version of the ADT-Bundle (yep, it's frustrating!).
Just uninstall the previous ADT.
Go to menu Help → About Eclipse → Installation Details
Uninstall all plugins which Id start with com.android.ide
Install ADT again from the update site.
DO NOT DO THIS
Warning: Please see the comments below this answer. These steps have had a negative impact for many people.
Click Help / Install new software...
Click on What is "already installed" (as in picture below)
In the new window you can uninstall the old ADT (uninstall Android Development Tools, Android DDMS, Android Hierarchy Viewer, Android TraceView, Android Native Development Tools and Tracer for OpenGL ES)
Restart Eclipse
Then again click on Help / Install New Software
Choose ADT... Install
I hope it helps!
After trying the approaches in other answers without success, I just installed a new bundle from http://developer.android.com/sdk/installing/index.html?pkg=adt and that worked fine.
Do the following:
As you don't want to re-download all the platforms again, copy the existing one from /OLD_ANDROID_SDK_PATH/sdk/platforms to /NEW_ANDROID_SDK_PATH/sdk/platforms.
When opening the new Eclipse from the recent downloaded bundle, make sure you reuse the previous 'workspace' folder. That will ensure that all your previous settings will be remembered.
After opening the new Eclipse on the previous workspace, please check if the used Android SDK is pointing to the new one (Eclipse preferences -> Android). It might be pointing to the old one, as you've reused the previews workspace settings.
With these steps, you should't have to reconfigure everything, and you won't need to spend time troubleshooting this BUG on this upgrade from Google Developers.
Good luck! ;-)
You need to uninstall the old version and install 23
uninstall:
Help > about Eclipse SDK > Installation Details
select Android related packages to uninstall
And then install V23.

I was getting the same "conflicting dependency" error on Mac OS X 10.9.3 and simply upgrading was not an option. What finally worked was downloading the latest Eclipse ADT bundle zip file from developer.android.com, extracting it and moving only "eclipse" folder to the place where my old eclipse folder was. (extracting the Eclipse ADT bundle zip file will give you "eclipse" and "sdk" folders).
If you decide to go the same route, first make sure you know what your Workspace path is. This can be found in Preferences. Then rename your old "eclipse" directory (not Eclipse.app) to something like eclipse-22.6.3, then move extracted "eclipse" folder into its place. Run new Eclipse.app inside, and when it asks you about Workspace, just enter the same path as you noted above. Or it can also be set later in Preferences.
Maybe worth adding is that to re-enable Android SDK Manager and Android Virtual Device Manager choose Window -> Customize Perspective -> Command Groups Availability and select Android SDK and AVD Manager. This will add these 2 items to the "Window" menu item for the current perspective (Java).
I didn't move the extracted "sdk" folder, because I already had sdk folder in the same directory as eclipse, which I have already updated to the latest Android tools. But if it makes you feel safer, you can also rename your old sdk folder (for backup purposes) and move the freshly extracted one into its place.
I faced the same problem and solved it. You need to uninstall the Android plugin entirely from within Eclipse (from the "about" section..), including trace view..
Then added the ADT Plugin again (https://dl-ssl.google.com/android/eclipse/) and install it.
The problem is solved!
I guess it's a bug with the SDK manager or ADT Plugin update mechanism...
How to update from 22.xx.x to 23.0.2 (my solution). This will beat the dependency issues.
I was suffering from this issue for days, and I have tried every single solution on this link, but no luck. I finally figured out a solution that actually works!
Please note that this solution works in Windows 7 (64 bit). It should probably work for other Windows operating systems.
Here we go:
download the latest ADT bundle from
http://developer.android.com/sdk/index.html#download
unzip it and open "eclipse" folder --> "plugins" folder
Now go to your old eclipse and open "eclipse" folder --> "plugins" folder, and copy everything inside.
Now paste them into the "plugins" folder of the (NEW ECLIPSE), but DO NOT overwrite anything.
While inside of the "plugins" folder of your new Eclipse, do the search. Type in 22. (notice 22 with a dot) and hit enter.
The search result will show up all the files or folders with .....22.6...... For example,
com.android.ide.eclipse.adt_**22.6.2**.v201403212031-1085508
Highlight all of these files/folders and hit delete key.
Make sure to update your old API/SDK to the latest version and load this sdk directory to work with your new eclipse.
or
You can watch this video, which shows you how to move all your SDK/API to your new SDK folder.
Link: https://www.youtube.com/watch?v=jPZpJdnbbN0
I have not tried to update from any other ADT versions, but I think it should work for any old ADT versions too.
Don't forget to backup stuff before attempting.
What I have just found is that you need to update your ADT plugin in your Eclipse (whether stand alone or ADT Bundle) before updating your build tool.
If your Eclipse installation points to the most recent Build Tool and your Eclipse is having ADT 22.x, it will show those errors.
What worked for me: (on Ubuntu 14.04 64-bit)
Installed an older version of Eclipse and ADT (from the Bundle)
This copy of Eclipse was pointing to an older SDK verion with old build tools (before 20)
Updated the ADT to v23 (via archive, in my case)
Pointed Eclipse to the latest version of build tools.
You may not have an older copy of Eclipse and Build tools, in that case you can uninstall latest build tool from SDK Manager and install the older copy.
Once everything starts working fine, do the above steps.
I am trying to upload older copies of such bundles somewhere on the Internet, will update the links here, once I am done uploading.
I found these instructions in a comment.
Download the newest version of ADT and use your existing workspace. This is actually the least pain-full upgrade you'll ever do. It didn't mess with the .android folder so I still had my original debug key. Only things missing were a couple of add ons I hardly ever use and they are easily installed into the new version.
Note don't install into your existing adt folder create a new folder so you can still fall back if the new install doesn't work.
On ADT-bundled Eclipse I had to first uninstall the ADT and then do a fresh install.
To remove the ADT plugin from Eclipse:
Go to menu Help → About Eclipse → Installation Details.
Select ADT plug-in, then click Uninstall.
After uninstallation install ADT from Help → Install new software.
For me it helped to delete Android 4.4W which is also API 20 and might be a cause for the conflict. So only install Android 4.4W or Android L until they fix it.
And (again this might only be for me) it only works in Android Studio not in Eclipse ...
I had to delete ADT and install it again.
However be warned, this caused me and one other person to have an annotations.jar missing errors in the Java Build path for certain projects, probably because it was trying to look for an old SDK, so upgrading projects is the next step I have to take.
The errors relate to libraries mostly, Google Play Services, Facebook SDK, ActionBarCompat.
For this step, you uninstall ADT, then put the URL back in to download them. The url is: https://dl-ssl.google.com/android/eclipse
I found a solution for the problem with "conflicting dependency". I don't have the same page of Daniel Díaz's response, but a page show "conflicting dependency", and I can't make anything.
The problem is that I'm not the owner of the file. Eclipse was installed in other session (on OS X). I have the right to read and write the Eclipse file, but I'm not the owner. Make a "chown" command on all Eclipse files to solve the problem. After, I have the same result as Daniel Diaz.
I hope this helps someone.
WARNING
There is now an update for ADT 23.0.1, but the Windows and Linux scripts are messed up, so wait with the upgrade!
You could check for example tools/proguard/bin/*.sh in http://dl.google.com/android/android-sdk_r23.0.1-windows.zip.
I did this to solve the same issue (in OS X):
Help > Install New Software > Add or select this repository "http://download.eclipse.org/eclipse/updates/4.3"
Under "Eclipse platform" select the newest version of Eclipse.
The installer will ask if you want to uninstall the ADT, click finish.
Restart Eclipse and install ONLY the ADT 23 using this repository: https://dl-ssl.google.com/android/eclipse.
Restart Eclipse and install DDMS, Hierarchy Viewer, Trace View etc.
Restart Eclipse again.
Hope it helps.
If Eclipse gives an error after uninstalling the ADT plugin from your Eclipse installation, try to edit file config.ini in the Eclipse folder → configuration. Find:
eclipse.application=
And change it to:
eclipse.application=org.eclipse.ui.ide.workbench
I hope it works for you too.
I simply went to my Android resources folder on my C:/ drive (C:/Android), deleted the 'eclipse' folder and all its contents. I downloaded Android Developer Tools once more and just moved over the 'eclipse' folder.
I started up and everything was fine; I had updated to version 23.
Hopefully this helps, possibly not suitable for everyone as some of you have Eclipse modifications but for someone who, like me, wanted a quick fix and get back to developing this seemed to be the easiest path.
I am using Eclipse v4.3 (Kepler), and this is how I solved my problem.
Goto menu Help → Install new software → click Add.
In the popup, give any name (I named it as Eclipse ADT Plugin), and in the link's place, use https://dl-ssl.google.com/android/eclipse/
Once you click OK, you will be displayed with new packages that will be installed and old packages that will be deleted. Don't worry about these packages. Click OK.
New packages will be installed, and this should solve your problem.
I just installed Eclipse Kepler (after an issue with a faulty update in Juno) and tried to install PyDev using the Install New Software option in Eclipse. Basically just following memory/online tutorials. After installing I can't see it in my Preferences pane. Any ideas why that might be so?
Thanks.
Yes, I have Java 7 installed.
UPDATE: A lot of users have suggested numerous solutions to this problem. There may be more than one correct answer below. See what helps you...
Too much!
After wasting 4 hours trying to install PyDev 3, I moved back to 2.8.2 and used the drop in technique instead of Add new software and it now works!
Download 2.8.2 from sourceforge
http://sourceforge.net/projects/pydev/files/pydev/
Uninstall PyDev.
Simply unzip the contents into the dropins folder below eclipse.
Restart eclipse.
After struggling with this problem for some days I wanted to share my solution to the problem - inspired by the above posts (kudo's to them).
My Configuration:
MacBook Air (intel) with OS X 10.9
Eclipse: Kepler SR1 installed (zip file extracted in the Applications folder)
My situation:
Tried to install PyDev via Eclipse Help --> Install new software...
Installation was succesfull, but PyDev didn't show up anywhere in Eclipse.
My solution:
In Eclipse go to Help --> Install new software...
Uncheck "Show only the latest versions of available software"
Select PyDev the usual way, but install the latest 2.x version instead of the 3.x version
Apparently PyDev 3.0 does not work with the default OS X configuration of Eclipse, Java and Python (don't exactly know why, though...)
I just figured it out.
You will need JDK rather than a JRE.
Download it here first:JDK Download
Install it.
Explore /Applications/eclipse/Eclipse.app/Contents/MacOS (where you put your Eclipse)
Open eclipse.ini
add
-vm
/Library/Java/JavaVirtualMachines/jdk1.7.0_45.jdk/Contents/Home/bin/java
You will change the version according to your situation.
Enjoy!
It happened to me too, but using Debian stable (wheezy, in my case).
I solved installing doing:
# apt-get install openjdk-7-jdk
After this, I checked that I had two alternatives of Java JDK:
# update-java-alternatives -l
And the output was:
java-1.6.0-openjdk-amd64 1061 /usr/lib/jvm/java-1.6.0-openjdk-amd64
java-1.7.0-openjdk-amd64 1051 /usr/lib/jvm/java-1.7.0-openjdk-amd64
Finally, I did:
# update-java-alternatives -s java-1.7.0-openjdk-amd64
After that, I removed pydev plugin from Eclipse, reboot Eclipse, install pydev (using Marketplace), reboot Eclipse, and now it works.

http://vas.davimas.name/2013/07/switching-between-openjdk-v6-and-v7-in.html and Richard's answer, above
Most likely you do not have java 7 or > eclipse 3.7 installed on your machine it is a requirement of pyDev 3 see here http://pydev.blogspot.co.uk/2013/11/pydev-30.html
The PyDev.org website states (http://pydev.org/manual_101_install.html) --
"""
Important requisite
PyDev now requires java 7 in order to run. If you don't have java 7, the update
process may appear to succeed, but PyDev will simply not show in the target
installation. Please double-check if you're using a java 7 vm in
about > installation details > configuration
before trying to install PyDev.
"""
This problem started to appear in my Eclipse after I removed the Java 7 runtime from my system (because the Java code I am building needs to run on an older version of Java, but that's unrelated). After I realized that I had lost PyDev, I reinstalled Java 7 and PyDev is working fine now.
Another option would be to rollback to the previous version of PyDev that does not require Java 7, but it would require a manual installation of PyDev and I would lose the convenience of automated updates. The best way forward, it seems, to run run Eclipse on Java 7 and switch those Java projects that need to depend explicitly on Java 6 to that JDK/JRE.
How I was able to get pydev to work in mac/eclipse is download the latest JDK as mention 100 times above install it and then do the following.
open eclipse choose preferences > java > installed JREs
click on "Search..." button it will auto populate the JDK 1.7 you just installed
Click ok
have a beer!
-Cheers!
Solved.
OSX Mavericks 10.9, Eclipse Keplar 4.3.2, PyDev 3.4
Problem: PyDev not showing up under Ecplise > preferences
Solution: Download, install and point Ecplise to JDK 1.7
Unistall PyDev
Under Eclipse > preferences > Installed JREs you probably only see Java SE 6
Download and install JDK 1.7 from http://www.oracle.com/technetwork/java/javase/downloads/jdk7-downloads-1880260.html
open terminal and run "/usr/libexec/java_home -v 1.7"
this will return the directory in which JDK 1.7 reside, something like /Library/Java/JavaVirtualMachines/jdk1.7.0_55.jdk/Contents/Home
Under Eclipse > preferences > Installed JREs click "add", select "MacOS X VM", click "next"
in JRE Home paste your version of /Library/Java/JavaVirtualMachines/jdk1.7.0_55.jdk/Contents/Home, give it a name and click "Finish"
Restart Eclipse and re-install PyDev.
Voila!
I had the same issue on Luna and found my mistake.
After checking the author in "Do you trust these certificates?" page, and I was able to successfully install pydev.
The page lets you proceed without checking it, and no error occurs and it was where I totally missed. Maybe it is useful for someone.
You can move back to 2.x.x:
Eclipse -> About Eclipse then click "Installation Details" button.
From "Installation History" tab choose last installation.
Click Revert button.
You will go back to chosen installation.
I managed to get the following to work with Eclipse IDE for Java Developers 4.4.1 Luna on OS X 10.9.5 Mavericks:
Download and install the latest version of the JDK (currently Java SE 8u25) from http://www.oracle.com/technetwork/java/javase/downloads/index.html. (Not the JRE!)
Navigate to /Applications/eclipse/Eclipse.app/Contents/MacOS (or wherever you have Eclipse installed) and open eclipse.ini.
Append the following to the bottom of the file (be sure to replace the version number with yours):
-vm
/Library/Java/JavaVirtualMachines/jdk1.8.0_25.jdk/Contents/Home/bin/java
Download the latest version of PyDev (currently 3.8.0) from SourceForge at http://sourceforge.net/projects/pydev/files/pydev/.
Unzip its contents to /Applications/eclipse/dropins (or wherever you have Eclipse installed) and restart Eclipse.
Hope this helps anyone who's still having the issue. Special thanks to Mohammed Lokhandwala and braineo.
Aha , It is solved just now.I show it in the following.
First , I use MyEclipse with jdk1.8,maybe some people dont know that Eclipse (or MyEclipse) has its own jvm , what is not "jdk" you downloaded and installed and the "built-in jvm" is default. You can check this out by clicking like this " Windows-->preferences-->Java-->Installed JREs" And I found my MyEclipse used the default jdk1.6 .Then I click "add" to build path of my installed jdk1.8 .
Second , I opened the configuration file named "myeclipse.ini" and check this in the following.
binary/com.sun.java.jdk.win32.x86_64_1.6.0.u43/bin/javaw.exe
Third , I replaced it with new path . Check the following out. It is new path.
D:/jdk/java/jdk1.8/bin/javaw.exe
Last , restart it .And you can find "PyDev" in "Preference".
Happy Coding with Python!
PS：Pycharm is good,and you can get it for free if you are a student or a teacher. click here
I was experiencing the same problem using java 1.7.0_101.
Updated to 1.8.0_91 and "voilá"! PyDev finally appeared.
After trying all of the listed ways to work with 1.7 I was still seeing error message when Eclipse tried to open the editors and navigators on startup. But when I created a new project it worked. Then I tried just closing all editors and reopening them and they too work. The navigator had also set itself to working set and showed nothing. When I switched that to projects it also started working.
The same thing happened to me. This is how i fixed it.
Click on "install new software" - it's under help.
Click on " what is already installed"
Uninstall PyDev
Reinstall PyDev BUT instead of the 3.3XX version, install the latest 2.XX version (i.e click on the drop down menu and select the latest 2.XX version)
It worked for me!
So I tired many of the suggestion above, and I think what finally got it to work is instal the JDK from: http://www.oracle.com/technetwork/java/javase/downloads/index.html. You might also need to uninstall the pydev plugin and reinstall it again. But after install the JDK 8, I got the Pydev to show up under preference.
menu Help > Install New Software...
don't fill "works with" but click on Add...
In the next screen, add the update site of PyDev and PyDev Extensions:
Name : PyDev and PyDev Extensions
Location: http://pydev.org/updates
and go on...
pydev 3 is buggy! Use 2.8 and you should be fine.
I also had this problem, wanted to use python3.4 as interpreter and it wasn't compatible with pydev 2.8 so after a few trials I found out that if you install pydev 2.5 everything works fine !! (At least on Eclipse Kepler).
I know this thread is old but I thought I might contribute my solution because none of the suggestions above worked for my Mac running Yosemite [10.10.2]. I hope this will be helpful to someone else. Despite updating to the latest JDK my mac kept reporting a wrong version. It turns out the symlink was point to the old version and fixing that issue got my pydev/eclipse working.
Find out the current default Java version
Java -version
Get installed versions
/usr/libexec/java_home -V
Navigate to the following folder and delete the current symlink
cd /System/Library/Frameworks/JavaVM.framework/Versions/
rm CurrentJDK
Create a new symlink pointing it to the newer installation substituting 'new-version' with appropriate version from 2 above. i.e jdk1.8.0_40.jdk
ln -s /Library/Java/JavaVirtualMachines/<new-version>/Contents/ CurrentJDK
Confirm your default version
Java -version
Restart.
Happy coding.. :)
I had to uninstall pyDev 3 and install 2.8 to get this working with Eclipse (V 4.4) and Yosemite (V 10.10)
The easiest way is just getting http://www.liclipse.com/ which has everything setup from the start... if you don't want to go that route (as LiClipse is commercial) you may want to try to specify the java 7 install manually:
Grabbed from http://pydev.org/download.html:
Well, the main issue at this time is that PyDev requires Java 7 in order to run. So, if you don't want to support PyDev by going the LiClipse route (which is mostly a PyDev standalone plus some goodies), you may have to go through some loops to make sure that you're actually using Java 7 to run Eclipse/PyDev (as explained below).
All OSes
Make sure you download/install the latest Java 7 JRE or JDK, try restarting to see if it got it automatically.
I.e.: in help > about > installation details > configuration check if it's actually using the java 7 version you pointed at.
If it didn't get it automatically, follow the instructions from:
http://wiki.eclipse.org/Eclipse.ini to add the -vm argument to eclipse.ini on "Specifying the JVM" to specify the java 7 vm.
Note on Mac OS: You can use the command "/usr/libexec/java_home -v 1.7" to get the base path for the JVM (though you also need to append "/bin/java" to the output of said command to the -vm arg in eclipse.ini).
Solution
Using standard Eclipse installation method:
In Install New Software, Add a new site to Work With. I called my entry PyDev Old and entered the Location:
https://dl.bintray.com/fabioz/pydev/old/site.xml
That has PyDev for Eclipse versions 2.8.2 to 4.5.3
Details
I am working with Indigo (3.7) and so need a version of PyDev that is older than 3.0.0. My JDK is 7 as noted elsewhere in this question. The option for Show only the latest versions of available software is turned off.
The standard advice for getting PyDev is to use http://pydev.org/updates and turn off the only latest option. That now only lists PyDev 5.
I had the same issue!
Just update all three SWs to the latest version and it will solve the problem.
Do like this:
update Eclipse to Luna Service Release 2 (4.4.2) 64-bit, then
PyDev - Python IDE for Eclipse 5.1.2 from Eclipse Marketplace and then
download and update the Java SE Development Kit 8u92 64-bit
It should work well now!
I had the same issue in Eclipse 4.4. Had to use a previous version of PyDev. It simply seems to be a matter of using the correct Java JRE/JDK and PyDev for the version of Eclipse you're running.
From http://www.pydev.org/
Release 5.2.0
Important PyDev now requires Java 8 and Eclipse 4.5 onwards.
PyDev 4.5.5 is the last release supporting Java 7 and Eclipse 3.8.
See: update sites page (http://www.pydev.org/update_sites/index.html) for the update site of older versions of PyDev.
Oct 2016:
Installed fresh new copy of Java JDK 1.8.0_102 took care of the incompatible OSX JRE 1.6
Installed fresh copy of Eclipse Neon 4.6.1
Followed pydev manual: http://www.pydev.org/manual_101_install.html
all working fine now...
First install and setup following applications as these are mentioned in above answers:
Jave (version 8 or greater)
Eclipse(version Neon/Oxygen or greater)
PyDev in Eclipse
Now go through following steps:
Eclipse -> Window -> Perspective -> Open Perspective -> Other..
Select PyDev in the list.
Click Open.
Now you are all set.
Cheers!!!
Make sure you install the 64-bit version of Eclipse if you can. If so you should be able to use the latest version of Pydev without any problem.
I'm using the Eclipse plug-in and my app runs on the following simulators: 9800, 9700, 8900 ,i.e, it is compatible with OS versions 5 and 6. However , when I package the application to run it on a device, the .alx file is generated correctly but there is also a folder called '6.0.0' with all the other files like .cod, .jar, etc. My question is, shouldn't there be a similar folder '5.0.0' with files for OS version 5? And if yes, then how do I go about generating it?Please help!
Ok just incase someone else is as frustrated by this as I was here's the solution:
Changing BlackBerry JRE to an Older Version (Eclipse Plug-in)
Just Check the project properties, it will be 6.0 JRE.
To be clear, you need to install the 5.0 in Eclipse by going through Help menu-Install Software, and add the Blackberry update site: http://www.blackberry.com/go/eclipseUpdate/3.6/java. Download the required OS from there.
Then, right click in the project, go to properties of the project and in it go Java Build Path, and under it, go to Libraries tab, you will find JRE to be 6.0, you need to change it to 5.0.
I've instaled the Java for Developer package provided from Apple for 10.7 and java apps are running fine
but eclipse cannot find the JDK root path and I cant either.
Anybody any ideas?
You can download the 10.7 Lion JDK from http://connect.apple.com.
Sign in and click the java section on the right.
The jdk is installed into a different location then previous. This will result in IDEs (such as Eclipse) being unable to locate source code and javadocs.
At the time of writing the JDK ended up here:
/Library/Java/JavaVirtualMachines/1.6.0_26-b03-383.jdk/Contents/Home
Open up eclipse preferences and go to Java --> Installed JREs page
Rather than use the "JVM Contents (MacOS X Default) we will need to use the JDK location
At the time of writing Search is not aware of the new JDK location; we we will need to click on the Add button
From the Add JRE wizard choose "MacOS X VM" for the JRE Type
For the JRE Definition Page we need to fill in the following:
JRE Home: /Library/Java/JavaVirtualMachines/1.6.0_26-b03-383.jdk/Contents/Home
The other fields will now auto fill, with the default JRE name being "Home".
You can quickly correct this to something more meaningful:
JRE name: System JDK
Finish the wizard and return to the Installed JREs page
Choose "System JDK" from the list
You can now develop normally with:
javadocs correctly shown for base classes
source code correctly shown when debugging
On newer versions of OS X you should find ALL JREs (and JDKs) under
/Library/Java/JavaVirtualMachines/
/System/Library/Java/JavaVirtualMachines/
the old path
/System/Library/Frameworks/JavaVM.framework/
has been deprecated.
Here is the official deprecation note:
http://developer.apple.com/library/mac/#releasenotes/Java/JavaSnowLeopardUpdate3LeopardUpdate8RN/NewandNoteworthy/NewandNoteworthy.html#//apple_ref/doc/uid/TP40010380-CH4-SW1
I have just ran into the same problem after updating. The JRE that is downloaded by OSX Lion is missing JavaRuntimeSupport.jar which will work but can wreck havoc on a lot of things. If you've updated, and you had a working JDK/JRE installed prior to that, do the following in Eclipse:
1) Project > Properties > Java Build Path > Select broken JRE/JDK > Edit
2) Select "Alternate JRE"
3) Click "Installed JREs..."
4) In the window that opens, click "Search..."
If all goes well, it will find your older JRE/JDK. Mine was in this location:
/System/Library/Frameworks/JavaVM.framework/Versions/1.6/Home
For Mountain Lion, Apple's java is up to 1.6.0_35-b10-428.jdk as of today.
It is indeed located under /Library/Java/JavaVirtualMachines .
You just download
"Java for OS X 2012-005 Developer Package" (Sept 6, 2012)
from
http://connect.apple.com/
In my view, Apple's naming is at least a bit confusing; why "-005" - is this the fifth version, or the fifth of five installers one needs?
And then run the installer; then follow the above steps inside Eclipse.
You can download jdk6 here http://support.apple.com/kb/DL1573
Wish it helps
I've installed on my iMac (Mac OS X 10.6.6) the Java update which contains the version 1.6.0_24 of the jdk. I think this update has changed the directory structure of the jdk, so now I'm not able to configure it on eclipse.
Before the update my eclipse were linked to this path: /System/Library/Frameworks/JavaVM.Framework/Versions/Current/Home which actually seems wrong.
Now I'm not able to link my eclipse to the jdk. Maybe this is the right path: /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home, but 1.6.0.jdk isn't a directory, so I'm not able to choose it in eclipse.
Has anyone experienced this problem? How can I solve it?
For me following jdk link is working fine on Eclipse:
/System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents/Home
It was my fault. I had also a jdk 1.5 manually installed and the update moved it away.
Probably I made a mistake restoring my jdk-1.5 to its correct location.
To solve my issue I just had to restore the symbolic links /System/Library/Frameworks/JavaVM.Framework/Versions/CurrentJDK, which has to point to /System/Library/Frameworks/JavaVM.Framework/Version.
the follow directory works:
/Library/Java/JavaVirtualMachines/jdk1.8.0_31.jdk/Contents/Home
without "System"
Execute /usr/libexec/java_home on the terminal shell.
It will display a list of all your installed JDKs
On MacOSX 10.10, jdk 1.8 with IntelliJ, I use:
/Library/Java/JavaVirtualMachines/jdk1.8.0_31.jdk/Contents/Home/
I was missing CurrentJDK folder as well, but I'm running Mac OS El Capitan.
In El Capitan it's not possible to modify the folder /System/Library/Frameworks/JavaVM.framework/Versions, since it is under the /System folder and SIP is protecting it (you can disable SIP, but I do not recommend), a custom CurrentJDK soft link is not allowed.
I got some legacy software which was searching for CurrentJDK, and there was no way to update the path. To solve it I had to install Java for OS X 2015-001 provided by apple (it's Java 1.6), which fixed the Versions subfolder structure by pointing to the old Java 1.6. Not the best, but it fixed my error!
