I try to use the FindBugs 3.0.0 in my Eclipse Luna.
After installing it it should be available on context menu of my JavaProject and under Window -> Preferences -> Java -> Find Bugs.
But it isn't there.
I tried it with installation from Marktplace, Update Site and downloading the Zip and putting it into my Eclipse installation.
Is there anything else I have to do to make it run?
Greeting

I had the same problem. My eclipse run on JVM 6 and FindBugs didn't work. I switch eclipse to use JVM 7 and this fixed issue. For more info how to switch JVM version that eclipse uses, see this eclipse Wiki
My installation of FindBugs 3.0.0 in eclipse luna works fine but I´ve installed the 3.0.0.20140629 version.
As a colleague of me, has the same problem hence I am not going to update it :)
Try to install the earlier version (not using the eclipse marketplace), this should fix your issue in the meantime.
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.
I have installed PMD in Eclipse Kepler using Eclipse market place.
But I am unable to access it after the installation.
When I go to Window → Preferences and search for PMD, I get no results.
Is there any other plugin available for source code cleanup?
Or: What needs to be done to install PMD in Kepler?
Thanks
I found the PMD plugin that installs through Eclipse Marketplace to be harder to use than the standalone one. Install available by an Eclipse update site here.
I've tried all these suggestions and now i have it working in Kepler; here's how to do it:
I made sure my Eclipse Kepler instance was using Java 7--it was.
The link from the eclipse marketplace did not work. It would show a PMD option for the individual projects properties, but there were no rules to select from. Also the main workspace preferences were not showing up.
I had to install it using this update site, as Jeanne Boyarsky mentioned:
http://sourceforge.net/projects/pmd/files/pmd-eclipse/update-site/
Restart Kepler.
The PMD option now shows up in the Windows->Preferences->PMD
The PMD project menu now shows up when right clicking on the project.
The install information on the web site for this plugin http://acanda.github.io/eclipse-pmd/getting-started.html says you must open the Properties for a project and look at the PMD tab.
If you've installed the PMD plug-in using the Eclipse market place then you're using eclipse-pmd which requires Eclipse to run on a JVM version 7 or later. If you're running Eclipse on a JVM version 6 or earlier and you're using eclipse-pmd 0.7 or earlier the PMD property page won't be visible.
To solve this problem you have to run Eclipse on a JVM version 7 or later. To change the JVM on which Eclipse runs you have to set the parameter -vm in your eclipse.ini accordingly. The Eclipse Wiki explains how to specify the JVM.
I'm struggling to get the Eclipse FindBugs plugin to work and am sure there's a schoolboy error being made somewhere.
I extracted the file findbugs-2.0.2-rc2.zip to a local folder C:\Program Files\findbugs-2.0.2-rc2 and running findbugs.bat, FindBugs works fine running it over a local Java (Eclipse) project.
I added the FindBugs update site, it found "FindBugs Feature, 2.0.1.20120712" and installed it. Restarting, right-clicking on an open Java Project doesn't display the "FindBugs" option (that this video shows).
I looked in Window > Preferences to try to find a way to inform the plugin of the local FindBugs installation (in Program Files), but couldn't find anything.
Uninstalling "FindBug Feature", I tried extracting the FindBugs Eclipse plugin zip file into Eclipse's plugins folder, but after a restart, saw no difference.
Help > About Eclipse > Installation Details > Installed Software lists "FindBugs Feature 2.0.1.20120712".
Can anyone please offer a pointer on where I'm going wrong here? Thanks!
Windows 7, Eclipse IDE for Java EE Developers Juno SR1, JDK 1.7.0_09, FindBugs 2.0.2-rc2
As suggested above, problem is likely caused by not having appropriate write access to the C:\Program Files\Eclipse\plugins folder.
Solution:
Close Eclipse. Restart Eclipse as Administrator (right click - Run as Administrator). Reinstall plugin. Restart Eclipse.
It looks like the Findbugs plugin wasn't installed properly and/or disabled by Eclipse. There can be several causes.
Multiple versions of the same plugin. To make sure this isn't the case, remove all Findbugs versions (installed manually and via the marketplace), and reinstall one (preferably via the marketplace). Watch for any warnings during installation.
There is a (dependency) conflict with another plugin. However, if this is the case I think Eclipse will warn in the log which other plugin is the cause of the conflict.
Rights problem. Make sure you have write permissions in the main Eclipse folder and all it's child folders.
I remember reading somewhere that installing Eclipse under the C:\Program Files\ in Windows can also be causing problems. Try moving Eclipse to a different folder, e.g. C:\Eclipse
Hi I also faced the similar problem but from my own experience i can suggest you the solution :-
Plz ensure that you are using eclipse version 3.6 or higher. findbugs 2.0 is not compatible with Eclipse 3.5(Eclipse Galileo).
1) Plz extract the findbugs zip file into eclipse folder(wher your eclipse is installed). This will automatically move findbug plugins into eclipse plugins folder. Restart the eclipse and you will find findbugs option on right clicking on project.
2) if 1 step does not work plz remove all the findbug jars for the eclipse plugins folder and place the complete folder into the eclipse dropins folder. Restart the eclipse and you will see the difference.
You can follow these step's to make findbugs work in your eclipse.
1.Install FireBug plugin from marketplace.
Help->Eclipse Marketplace ->then search for FindBugs
2.Configure FindBug for your project
using Maven Without Maven
This worked fine for me using eclipse juno.
I'm using Ubuntu 12.04, and to install Eclipse Juno I downloaded it from the official site (I don't use apt-get nor software center)
After updating it from help > check for updates menu, my Eclipse cannot make new project. When I hover File > New, there isn't any menu to select (as the usual Java Project, C++ Project etc.), only an unselectable text like this:
< No Applicable Items >
Anyone know what causes this?
nitind's answer above helped solve my problem. I was using eclipse java ide juno on windows and i could not see any items under File -> New or under Window -> Show View. I noticed eclipse had defaulted to using the Java-EE perspective. Following nitind's suggestion I changed it to the Java perspective and can now see all the menu items. thank you!
I had the same error when i first started the program, but i looked into it, and I saw that the workspace already had .cpp and compiled files in it which i had compiled earlier with a different program. To fix the error, I just changed the workspace to the default, and it worked fine.
I was using eclipse CDT Kepler with java 1.6.0_27. I then tried it with java 1.7.0_25 and eclipse Juno and this method resolved the error in any of these instances.
Try using the default workspace and it should work.

Nikita
