I was developing a plugin, using Eclipse IDE for java developers (Version: 2021-09 (4.21.0)
Build id: 20210910-1417)
During development, when I run it as an eclipse application, it opens a runtime-Eclipse application where the plug-in is present. In my setup this new runtime-eclips app opened from a folder next to the workspace, where C codes were present. (and my progrem would get the tests run in C , and get the results from it's exe)
Then I downloaded the Eclipse IDE for committers, which is a newer version. I downloaded it as a zip and after unpacking I run the eclipse.exe. My program had problems opening the runtime-Eclipse application in C there, so i went back to the older one which is installed on my computer.
After opening the original eclipse, on which I was working and had no problems, I was hoping everything will be fine. It opens the IDE for java developers (same version, same build) but I have the same problems with the runtime-eclipse application as the one I run as an eclipse.exe , (not recognising the C code?? I don't understand).
When i try to run the plug-in I get this error.
And when the runtime-app opens i get this error.
I cannot create C projects anymore on the runtime-app. I don't know the reason behind this.
Also I have billion of these
["java.net.UnknownHostException: downdload.eclipse.ort"]
[" org.eclipse.equinox.p2.core.ProvisionException: Unknown Host: http://downdload.eclipse.ort/eclipse/updates/4.2/content.xml "]
Thank you in advance!
I don't know if it is possible or not, since seemingly it did not update the older eclipse IDE. If it can be restored the way it was before i run the eclipse.exe, I would be happy.
eclipse.ort is obviously a typo, it should be eclipse.org, I don't know where it is coming from - but its possible you enter it yourself as update site
the runtime error means eclipse cannot resolve all dependencies, which means it could not load bunch of plugins including yours, you need to figure out why on your own, its not possible to debug this remotely, its best to start from the scratch in the new workspace
The solution was easier than expected. The run configuration was modified by the other eclipse version. It was not launched with every plugin. only a selected handful
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.

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 have Eclipse IDE for Java EE packages installed. How can I add the C/C++ IDE to the current Eclipse install? Or is there a better way to do this?
Use Help > Install New software to open the Install dialog. There, you'll need to select the right update site from the drop-down list at the top. Depending on which version of Eclipse you have, it will most likely be Indigo or Helios.
After selecting the update site, the list below will populate with available features to install (be patient, it might take a minute). Look for the "Programming Languages" group in that list, expand it, and check the box next to "C/C++ Development Tools." If desired, you can also select the "incubation" features for C/C++ or CDT.
Click the Next button and follow the prompts to download and install CDT.
I use Eclipse Java EE IDE for Web Developers, Version: Neon.3 Release (4.6.3RC2) on Ubuntu. Here are the steps I installed C++ plugins:
Help > Eclipse Marketplaces..
In Find input box, enter C++
Scroll down to locate Eclipse C/C++ IDE CDT 9.2 (Neon.2)
Click Install
Note: you may see different C/C++ IDE CDT version if you use a different version of Eclipse Java EE IDE
In addition to the steps above to follow, I want to share a side effect of installing C/C++ modules in Java EE Eclipse: your custom hotkeys may not work.
The fix is:
Try to "Restore command" in "Preferences" - "Keys".
If it doesn't help, you can try to close Java perspective and reopen it. That did the trick for me.
I noticed that when the installation finishes and we restart, we see a C++ welcome screen. I guess that after a installation of CDT, this perspective and its hotkeys takes precedence over Java perspective, thus, reopen Java perspective make Java hotkeys take precedence over C++. But it's more like a bug.
I decided to take a look at Clojure and thought the best and easiest method for me would be to use Netbeans with the Enclojure plugin as I didn't want to have to learn Emacs at the same time. I installed Netbeans 6.9.1 together with the latest JDK using the bundled install (on Windows 7). All went smoothly. I then followed the instructions at http://www.enclojure.org/gettingstarted for installing the enclojure plugin.
When creating a new Clojure application I get the following and see no project files :
java.io.IOException: Could not connect to URL nbresloc:/org/enclojure/ide/templates/project/ClojureProjectTemplate-1.1-distribution.zip. No such resource was found.
Maven is working using mvn --version
I have installed on both Windows 7 and Ubuntu 10.04 (same result).
I have looked on the Enclojure forum and there is a recent open thread for this issue, but it is not solved by anybody presently.
I have Java SE enabled in Netbeans
I have tried enabling the different platform versions of Clojure, 1.0.0, 1.1.0, etc..
The REPL seems to be working happily in Netbeans : (printf "hello") hellonill
I did try ClojureBox on Windows 7, but again that's Emacs, but emacs failed to start the server and hung there and became totally unresponsive.
I come from a .Net background (not Java) so my knowledge of the Java environment is somewhat lacking. My reason for looking at Clojure and not Java.
I am new to Netbeans
If you're interested in a working Maven pom, here is one I've used with Enclojure successfully:
http://puredanger.com/techfiles/100624/pom.xml
There are some project settings you'll need to change and a few dependencies to remove but it might be a good start. In general, I usually create the pom first and then just import the project into NetBeans rather than using the NetBeans options to create projects.
By the way, the REPL work in Enclojure has been split and is coming soon to the Eclipse plugin Counterclockwise.
I had written a small post on it on my blog.
Anyways here is the procedure:
On searching realized that this is a common problem for installing it on > Netbeans 7.. But with some manual tweeks managed to install it. Here are the instructions to install on Netbeans 7. plus:
Install Netbeans 7. You need only the Java SE version.
First Run of Netbeans after installation. Activate feature Java SE
Activate features is on the Start page or from Tools,->Plugins>Installed, click ‘Activate next to the Java SE support
Install Maven: It is HIGHLY recommended that you install maven: http://maven.apache.org/download.html
Go to the Netbeans->Preferences, click on the Miscellaneous tab and make sure the External Maven Home path is pointed to your maven install
Download the EnClojure 1.5 version from here. If you want to manually build, you can do that by following the instructions from here.
After downloading the file, In Netbeans: Goto:- Tools ->Plugins->Downloaded->Add Plugins->Downloaded
Then browse to the downloaded file. Later install by clicking at the “install : button.
Restart and you are on the go.
Visit here to build and run hello world project.Basically building the EnClojure 1.5 manually is the tough job. I hope above was useful.
