To upgrade to a new version, the eclipse FAQ suggests to add a new repository and then install available updates. Upgrading to Neon, the corresponding repository is http://download.eclipse.org/releases/neon/.
On this page, it says:
NOTE: Due to structural changes you cannot update from a Mars (or prior) all-in-one package to a Neon version. If interested in the technical details, see bug 332989 and bug 490515.
I still tried to above procedure, but no updates were found. What is the best way to upgrade from Mars to Neon? A complete new installation? How do I preserve my settings?
The note on the repository page is right. Thanks to your report, I edited the FAQ to make it clear that upgrading packages from Mars to Neon is not supported.
Instead you need to to a fresh install for Neon (or later).
I tried to upgrade in the recommended way, by adding the repository links and doing an update, but then I got a lot of conflict messages. I foolishly tried to remove the conflicting software components, until it told me that Eclipse itself was the conflict! I posted my problem to the Eclipse Forums, and was told by a regular with tens of thousands of posts that Neon was so different that I should not even try to upgrade, just create a new installation. When I tried to do that however, I got lots of warnings "That the artifact download is progressing very slowly from ..."
It is not possible to upgrade from Mars (or earlier versions), so a new install is needed.
This can be in parallel with the old install. From the FAQ:
Fresh install
If you prefer not performing an update (for example
because some 3rd-party content isn't ready for the current release of
Eclipse IDE so the update reports conflicts), you can still download a
fresh install of the Eclipse IDE and install it in another location on
your filesystem, and use it together with the previous version.
To do so, download a new build from the Eclipse download Web site
(https://www.eclipse.org/downloads/eclipse-packages/) and run the
installer or unzip the archive in a new directory. We strongly
recommend against installing/unzipping over your existing version of
Eclipse IDE as it may corrupt your installation.
When you start a new version of Eclipse IDE, you can use the same
existing workspace folder that you were using with older version. The
workspace will be migrated to newer version and Eclipse IDE will to
reuse all configuration. The workspace is forward compatible
How to install SVN Repository Exploring plugin for Eclipse? My current Eclipse version is 2.6.1. it does not have SVN Repository Exploring Perspective.
Update your eclipse firstly.
Help --> Eclipse MarketPlace, search subclipse, click install, and then follow the instructions to finish up the installation process.
I highly advise you to update your Eclipse instead of trying to make the plugins work with the obsolete version of the IDE. You will encounter numerous issues in order to make the plugins work with older versions of the IDE since most of the plugins require atleast the 3.4 version of Eclipse to function properly. You will need to dig the archives to find older version of plugins and then some-how make them compatible with the older eclipse
My adivse, download (not update) the latest version of eclipse from the official website. I believe the latest version in use is 4.3.1.
Update : The latest version in use is now 4.4.1 (Luna)
Did you try Help -> Install New Software -> All Available sites
There you can select SVN plugin. try to install
You can add a particular site there, for example 'http://subclipse.tigris.org/' and select the SVN Version as per the Eclipse and trying referring it from 'Help > Install New Software > Add Site' .
Hope this helps.
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.

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.
In the past I've always downloaded the new version, and then manually reinstalled all of the plugins I use - but this is tedious in the extreme.
Is there a way to upgrade Eclipse "in-place"? How do I do this exactly?
The approach below worked for me, and seems to be the easiest. It's from this eclipse FAQ and slightly modified for clarity:
For upgrading from Eclipse 3.5+ to 3.6+
Help -> Install New Software
Enter the release update site url eg. 'http://download.eclipse.org/releases/indigo' <- if upgrading from 3.5 or 3.6 (Helios) to 3.7 (Indigo)
Click Add
Click Cancel
Help -> Check for Updates
Note: The original URL has changed. (I've left the original link for posterity)
following the NEW FAQ instructions
Also you may have to remove any incompatible updates plugins before proceeding.
(For Example: JBoss Tools has different versions for Helios and Indigo that are incompatible)
Update: I didn't try this when upgrading from 3.x to 4.x (Juno). I just set up a whole new workspace. I think I read somewhere that doing that is the safest approach to upgrading major versions.
As of 3.7 (Indigo), you may export/import install configurations via the
File > Import/Export > Install menu.
This allows you to install a new release of Eclipse, point it at your
existing workspace, and install your plugins from an older installed
copy.
If you always download all plugins manually and then deploy it by copying to dropins folder, then while migrating to newer version, just need to copy that folder to the new eclipse.
And even not all plugins will support newer version of Eclipse so I guess there is no really easy way available to do the migration.
The answer is, there is none. It's pointless to speculate here as to why the Eclipse community chooses not to make one. They haven't.
How do I manually install a plugin in Eclipse? Or how do I force the installer to install a plugin, even when it doesn't want to?
E.g., I am trying to downgrade a plugin (an update for which contained a bug that I cannot work with). I have tried going to About Eclipse -> Installation Details -> Installation History and selecting a previous configuration, but I get errors trying to revert to one. I have also downloaded the all-in-one update for the previous version of the plugin I want to roll-back. But if I go to Install New Software -> Add -> Archive then I can select the update, but when I try to install it I am told that the plugin I'm trying to install "will be ignored because a newer version is already installed".
I need a way to install the plugin manually or force the installer to install the older version of the plugin. Doe anyone know how this can be achieved?
You should uninstall the current version of the plug-in before installing the older one.
go to About Eclipse -> Installation Details -> Installed Software and uninstall the plug-in you want to downgrade.
then try again installing it going toInstall New Software -> Add -> Archive...
saluti
There is some difference between each Eclipse version to locate the feature. Which version did you use ? 3.3 ?
I can't say where you will find the option but start by removing the installedv ersion and retry to install the older.
If you realy want to install it you can also try to find the archive and extract the content into your Eclipse folder (It may have two folder features and plugin).
/!\Take care about plugin dependency and compatibilty/!\ Make a backup of your installation before.
You should remove the top level plugin.
Try to reinstall it without selecting the last version of the plugin. May be you can select and older version in this step or install the expected sub-plugin version later.
Or
Find which version of "epp.package.php" use the plugin version you need. Install it. And if needed try to update some plugin/sub-plugin and check if your sub-plugin is not in the update list.
