I have installed eclipse checkstyle plugin. It installs properly but is not showing up in windows -> preferences. Currently using Mars.2 version. Have tried installing from both the update site http://eclipse-cs.sf.net/update and offline archive zip file and both install smoothly.
I have tried uninstalling, restarting eclipse in admin mode and installing again; and restarting ecplise with -clean -refresh options. None of these solutions have worked for me.
Am I missing something here?
As long as Mars is an old release, there may be some incompatibility problems between it and the plugin. You should check Eclipse Neon, where plugins should work without those issues.
If installation works but a plug-in then doesn’t show up in the UI, it may mean that its OSGi bundles fail to resolve. To check that, launch Eclipse with the -console switch; this opens the OSGi console in the terminal you used to start Eclipse with. Then, type the following:
ss | grep INSTALLED
This way, you will get a list of bundles that are merely INSTALLED but not RESOLVED or STARTING. If a Checkstyle bundles is among them, you have found your problem.
You can obtain further information suitable for a bug report to the Checkstyle developers by typing
diag $NUMBER
where $NUMBER is the number listed in the first column of the INSTALLED bundle.
Overview
I am running Ubuntu 15.10 with Eclipse Mars 4.5.2 (from the Oomph installer) and and Java 1.8 and Python 2.7. I am attempting to the PyDev 5.2.0 plugin for Eclipse. Installing with Eclipse's update manager seemed to go okay. The only problem is that I can only see PyDev related options when I run Eclipse with sudo.
What I have tried
I made sure to set the java VM path in the eclipse.ini file so the Eclipse binary runs with Java 8.
I added Java 8 to Eclipse's JREs and set to be default.
I tried running the Eclipse binary with the -clean option.
The first two didn't allow me access to the PyDev options in Eclipse. Running as a normal user with the -clean option did let me see the PyDev options, but running as a normal user without -clean made the PyDev menu options invisible again.
Finally, I noticed that running Eclipse as root made the PyDev options appear again. This suggested that there was some ownership or permission problem. Since my Eclipse installation and plugins are in my home directory, I made sure my user has ownership over everything in the home directory. I also reviewed the permissions of files related to the PyDev plugin, and it appears I have the appropriate permissions, but since I do not know which permissions each file ought to have, I am not sure.
I am not sure what is going on. It is especially surprising given that I was able to install the CDT plugin not long ago without any hassle. It's also possible the problem might be related to how root's environment is configured compared to my user's, but being able to access PyDev when running with -clean seems to vanquish that theory.
I could just run Eclipse as root from now on, which isn't that big of a deal. However, it is quite annoying not knowing why this is happening, making me feel like I don't have control over Ubuntu and Eclipse.
My guess is that you have the eclipse configuration folder not accessible by the current user (or some other folder inside the .metadata).
Try verifying/fixing the permissions on those folders (I don't exactly know where those folders go on the default ubuntu install, but on windows it's eclipse/configuration and the .metadata is where you point your workspace to).
In my case, upgrading to Ubuntu 16.04 solved my problem. After the upgrade, PyDev was working normally in Eclipse.
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.
Windows 7 64 Bits, Eclipse Indigo, SlickSVN 1.6.17 all installed with path to the libraries entered in windows.
Why do I get the message JAVAHL (JNI) Not available and why does eclipse not load these libraries?
Have you tried installing SilkSVN as suggested on the subclipse official FAQ?
Then on Eclipse/MyEclipse go to Window>Preferences>Team>SVN Change the client to SVNKit v1.XXX.
That did the trick for me.
Did you close down Eclipse before running the SlikSVN 64 bit installation?
I had the same issue initially.
Close Eclipse, rerun the SlikSVN install, choose Repair Installation.
Once complete, open Eclipse, and then you should have the "JavaHL Slik SVN" option under Window/Preferences/team/SVN
I had the same issue. It turns out that the FAQ is helpful indeed, because:
As of the Subclipse 1.8.x releases, native 64-bit Windows binaries are
included with Subclipse so it includes everything you need. For
earlier releases of Subclipse follow these instructions:
If you are using a 32-bit JVM, then Subclipse should just work. If you
use a 64-bit JVM then you need to provide a 64-bit version of JavaHL.
One such distribution is SlikSVN which you can get here:
http://www.sliksvn.com/en/download
With that package installed, Subclipse should find JavaHL on PATH and
just work.
The key here is the PATH variable. In my case I had another svn client installed that came before in the path. When I changed to C:\Program Files\SlikSvn\bin\ be the first folder in the variable, all worked.
Now I can find "JavaHl Slik SVN" under SVN Interface. The solution was to uninstall Subclipse and to reinstall it. When reinstalling Subclipse, I removed the check on "javahl client adapter (required)" (or similar).
1) Uninstall existing subclipse plugin:
Uninstall subclipse
2) Download these three files:
subclipse-4.3.0.zip
subclipse-javahl-1.12.0.zip
subclipse.javahl.update-1.12.0-SNAPSHOT.zip
3) Install them manually one by one by following theses instructions:
http://www.microfocus.co.jp/manuals/ED23/html/GUID-70E8158C-8618-4228-9495-6AFF4CB7E8DB.html
Ω) If not suitable in your case:
Install this: Subversive-4.0.2.I20160902-1700.zip (works with eclipse 2019-06)
I've just bought a new computer x64 and intalled windows 7 and Eclipse Helios x64. When I tried to install subclipse it didn't work... after a few times trying to install it and getting stuck when eclipse was trying to check the dependences, I did get to install it but it simply didn't work.
When I chenged the perspective to SVN Repository I got an error. Anyway, I downloaded Eclipse Helios x86 and also got stuck on the dependeces checking part. But after a while trying it was installed and now it works.
But the thing is that I want to install eclipse helios x64 since I have a x64 computer.
Did anybody have the same or a similar problem? How did you solve it?
Thanks.
I'm using Eclipse64 with a working SVN plugin.
But I changed the SVN Client interface from "Java HAL" to "SVNKit" which works much better. I installed this module via Yoxos and then switched in the preferences Team > SVN > SVN interface to SVNKit.
If you want to stick to JavaHL way of accessing the repository, you can also install the 64 bits version of JavaHL.
Referenced here - look at the paragraph saying Windows 64-bit. It will redirect you to slik subversion client
You can install the whole client (I could not install only javahl with the custom install)
To make sure it is taken into account, edit your eclipse.ini file and, after the -vmargs line, add -Djava.library.path=C:\programs\slik (or if you already have an item for the jni path, add your own path).
