I work on Mac OSX Lion and ever since I've installed the Zend Debugger and gotten it to be able to debug php web applications, I often encounter this Eclipse startup error:
Error creation extension for extension-point
org.eclipse.php.internal.debug.daemon.communication Plug-in
org.eclipse.php.debug.core was unable to load class
org.eclipse.php.internal.debug.core.zend.communication.DebuggerCommunicationDaemon.
An error occurred while automatically activating bundle
org.eclipse.php.debug.core (258).
The error log contains the following stack trace:

This error often goes away when I just restart eclipse a few times. I've googled for solutions and tried reinstalling eclipse a couple of times. This error only seems to occur if I have both ADT (Android Development Tools) and PDT (PHP Development Tools) + Zend Debugger installed.
Please let me know if you have information about how to solve this problem. On a related note, I never really got the PDT + Zend debugger to work (as in debug) PHP apps on Windows.
I have seen this error a few times, even in the Zend Eclipse PHP version. It only seems to happen when two things are true:
1) The "breakpoints" view is visible on eclipse start (that is, you can see where breakpoints would be listed)
and
2) The file open and active in the editor is NOT a PHP file
For example, I got this repeatably with a CSS file open in the editor on the debug perspective with the breakpoints tab active.
To get around it: Start eclipse and ignore the bug about loading the plugin (for now). Make a PHP file the active document in the editor, and change from the debug perspective to the PHP perspective. Close eclipse and restart. On restart, the error should be gone and debugging should be active again.
I can't guarantee this is the solution everytime, but I can reliably replicate this failure (and solution) with the breakpoint/non-PHP conditions described above.
I had a similar issue (yours came up top of Google when I pasted my error message) after a few similar and different errors I decided to check my Eclipse workspace settings after an alternative workspace of mine worked and debugged fine.
It turns out my PHP executable pathway was empty (after having previously set it), so I added it back in. No problems so far.
(i.e. here...) Eclipse -> Window -> Preferences -> PHP -> PHP Executables -> Add/replace/reselect here.
UPDATE:
sometimes the simplest thing is to select 'Skip all breakpoints' under the 'Breakpoints' view (which opens in debug perspective). Then restart Eclipse. I have had similar error messages since first answering and that usually does the job (of course you can deselect 'Skip all breakpoints' after that from the same place.
This is a workaround instead of a solution, but so far, it's going good:
I downloaded and installed Eclipse for PHP Developers(aka Zend Eclipse PDT) version 3.0.2 from Zend website and I'm now able to debug Wordpress and Joomla, both pretty complicated projects as far as PHP goes.
I will update if I experience a problem.
I am using Eclipse Indigo on Ubuntu 12.04 and I received this error after installing Java 7. My PDT settings which used to work stop working. My solution was to uninstall PDT and reinstall it. I am not sure if this is relevant to your question but it might solve the issue.
Help -> About eclipse platform
click "Installation details" button
click php development tools (PDT) sdk feature
click uninstall
follow prompts
reinstall pdt in the normal way
My previous debug launches were deleted but my old project was left untouched. I re-ran a debug from Run -> Debug Configurations.
I've only ever gotten this after closing down an Eclipse php project that I've enabled various breakpoints in.
My workaround is once the project opens and I get the error message I select skip all breakpoints, close the project and re-open it. I then deselect the skip breakpoints and start working. The error, at least in my case happens randomly and for no other reason than I closed the project with breakpoints enabled.
Wish I had a more technical solution or fix but I decided my time was better spent working on actual work than chasing this deeper.
The problem happened when I closed Eclipse while a project was still running in debug mode.
I did more or less the same as #rahvin_t to fix it.
Run > Skip all breakpoint. Close Eclipse, start eclipse and I could start the project again.
there are a few errors that happen on start-up similar to this one. They seem to occur when there are 'unusual' files open in the editor (e.g. css or javascript)
What usually works for me:
Close all your files in Eclipse (Ctrl+Shift+W)
Restart Eclipse.

I am running Windows XP and Eclipse 4.2.2 Build id: M20130204-1200 and I have lost my Debug and Launch tool bars. I have tried Windows>Reset Perspective (original values) and Window>Customize Perspective's (Tool Bar Visibility and Command Groups Availability) tab options. I have tried the Layout option on Debug view. All failed to bring them back. Right now, I am looking at Tool Bar Visibility tab and a message that says: <"Debug" cannot be made available because it is in the unavailable "null" command group.> However, the Debug checkbox in Command Group Availability is checked.
I have also tried right-click and Reset on the perspective buttons.
Switching to another eclipse installation (same machine) did not help either.
Rebooting does not help.
Are there any text configuration files where this data is stored that can be manipulated outside eclipse?
I had this problem in Eclipse Kepler, it turns out it was caused by PyDev plugin. I fixed it by uninstalling the plugin and right-clicking on the Debug perspective button and selecting Reset.
I had already installed a fresh copy and the problems persisted. But, encouraged by user714965 comments, I tried again but that did not resolve the issue. Then, I threw away all eclipse installation folders (to recycle bin), re-installed fresh copy, and the problem persisted. Then I started a new workspace, and it seemed like the tool bars were back. Then restored previous eclipse installations and they had the Debug toolbar as well!
I am thinking somehow the customization config files were broken. It would be nice to know where the these files are stored (my original question): Are they global for each user on the machine or are they workspace specific? It seems to me that some customizations are global, while others are project specific.
May be it is time to try the new Android Studio :-)
Seems as your eclipse is broken. The fastest way to get it back running will be downloading a fresh copy from eclipse.org. You can continue using your current workspace so your settings will remain. But you have to re-install all plug-ins... I'm always keeping a backup of a fresh release with the plug-ins I'm using. I would suggest you to do the same in the future.
Update 28 May 2013:
I have found a work around for this. Though this is not always works MOST of the time it does.
In Eclipse > Preferences > General > Startup and Shutdown
uncheck the option "ClearCase Remote Client plug-in"
Every time I start the problem workspace, before doing anything (like click on any resource or click on project in project explorer) I connect to the ClearCase repository.
This seems to calm down the error most of the time. Also, the Eclipse shortcut that I have on my desktop, has -clean option set in it. So when I start the eclipse my eclipse already starts with the clean up option. Though not sure if it has any bearing on the problem.
However not sure if this will help in a situation when I am working offline; when I can not connect to the ClearCase repository.
Update 21 May 2013:
At this time it looks like there is no resolution for this except a CCRC plugin upgrade.
For now marking VonC's answer as correct. Will update the post if I find a better solution.
I created a fresh new workspace and setup the workspace and so far I do not see any problems so far. Still not sure what was wrong with my workspace though.
==================================================
I have been having this problem for quite sometime on one of the workspace.
Error:
I am seeing the following error pop up with the error message; and will NOT go away.
An error has occurred. See error log for more details.
Could not initialize class com.ibm.rational.team.client.ui.model.common.ImageManager
Symptoms:
It happens only in one work space almost all the time.
Every time I restart this workspace, when ever I click on any projects in project explorer or any open file, it causes the error pop up to come up.
It goes away if I close all files, close the offending project and then delete the project. I fire up eclipse, re-import the project and the issue goes away only as long as I continue using the eclipse. Once I restart the eclipse the same problem persists.
What I have tried so far:
start eclipse with -clean option --> It does not solve the problem.
I have enabled the "Refresh workspace on startup" option in "Eclipse > Preferences > General > Startup and Shutdown" --> this does not solve theproblem.
I deleted the folder "org.eclipse.core.resources" under "Offending_Workspace > .metadata > .plugins" folder --> this has no effect. The problem persists as mentioned in Symptoms3 above.
System Info:
Windows 7 Enterprise Edition 64 bit.
Eclipse 3.7 Java EE developers
CCRC plugin Version: 7.1.0.0 , Build id: 7.1.1.03.00_2010C.D100803
Is there anything that can be done to resolve this. It's frustrating to work with such a broken plugin, that practically hinders ones work.
Any suggestion will be helpful.
This looks like PM38965 and there is no other solution than upgrading:
A fix is available in ClearCase versions 7.1.1.8, 7.1.2.5 and 8.0.0.1
You can see it listed in this release note:
PM38965:
Addresses a ClearCase issue where the ClearTeam Explorer produces a "Could not initialize class com.ibm.rational.team.client.ui.model.common.ImageManager" error intermittently when performing various operations.
The OP reports a workaround:
In Eclipse > Preferences > General > Startup and Shutdown, uncheck the option "ClearCase Remote Client plug-in"
Every time I start the problem workspace, before doing anything (like click on any resource or click on project in project explorer) I connect to the ClearCase repository.
This seems to calm down the error most of the time.
Also, the Eclipse shortcut that I have on my desktop, has '-clean' option set in it. So when I start the eclipse my eclipse already starts with the clean up option.
Though not sure if it has any bearing on the problem. However not sure if this will help in a situation when I am working offline; when I can not connect to the ClearCase repository.
The '-clean' being a local operation, it will have the same effect offline or online.
I launched Eclipse earlier to jot down a snippet and was faced with the following as an error when I tried to run a fresh project:
An internal error occurred during: "Compute launch button tooltip".
That popup window shows as soon as I mouse-over the run icon in the top bar, or if I right click on the class in the explorer window and select any of the run/debug options.
After doing some research on the error, I see several people who posted similar messages but they all have been fresh installs of Eclipse. So note that this is not a fresh install, and that Eclipse was working fine earlier today. Also note that not only does my new project not run (with the normal main method), but projects I was running earlier have all stopped working with the same error.
Finally, also be aware that after seeing other people's suggestions on fixing this, one specifically said to select run configurations from the top of the page run menu. When I selected run configurations from this dropdown, I got the following message:
Exception occurred creating launch configuration tabs
Reason: Plug-in org.eclipse.jdt.debug.ui was unable to load class org.eclipse.jdt.internal.debug.ui.launcher.LocalJavaApplicationTabGroup
After that message, the run window opens but all of the tabs are missing. Like where you can set the display width and height, and the other tabs, they are all missing from the window now.
I was using Eclipse trouble free earlier today and I am sure no updates took place between when Eclipse was working and now. My question is of multiple parts: What is wrong in a nutshell? What could have caused this?
Got this from another site of some guy who got this same error after upgrading.
Worked for me as well.
Apparently putting the following line in your eclipse.ini helps:
-Dcom.ibm.icu.util.TimeZone.DefaultTimeZoneType=ICU
Try setting the launch properties in:
Window>Preferences>Run/Debug(Expand)>Launching(Click)
Under launch Operations menu set it to:
Always launch the previously launched application
Click:
Apply>Ok
I never found out what went wrong, but a reinstall of eclipse fixed it. All projects survived seemingly undamaged.
Thanks for the reply on the .ini but that did no good.
I had same error today - in an eclipse installation (Juno SR2 64bit) that has been running fine for months.
0: There were no changes on svn for my projects since yesterday (when it was running fine).
1: I restored the workspace from a 'Windows 7 -> Properties -> previous copy' backup. This failed because the directory structure of the '.metadata' contains folders with a deeper structure than is supported.
2: I restored the workspace from a overnight archive (gzipped so file depth is not an issue).
This had no effect.
3: I tried to restore the eclipse installation directory (which seems to be updated an awful lot) from a 'Windows 7 -> Properties -> previous copy' backup. Again this failed - because of folder-depth issues (Note: it is installed in the root directory of my disk - so there is actually no way to use a restore on this installation!)
4: Had to delete the .metadata from my workspace and reinstall eclipse (and all the additional plugins), and re-import my projects, and setup all the servers, and android, etc, which took many hours.
The moral of the story? Backup both your workspace AND the eclipse installation every night manually. Windows Restore will NOT save you. Backing up your workspace is NOT enough.
I had the same problem using eclipse mars. I cleared the folder .recommenders\index
And that solved my issue.
Hope it helps.
incase you are having the eclipse files which you have downloaded from the official site .Just extract those file in the same folder where your previous eclipse was installed and select replace all.
best solution
I also encountered this issue, the reason why this issue occurred on my project was due to I was missing the JRE System Library in the root folder of my project.
To solve this issue, make sure you have the libraries like JRE System Libraries on the root folder of your project.
I have just installed Eclipse 3.5 for Java EE developers ("Galileo").
I need to add an extra plugin, but when I select the "Install New Software ..." menu item, nothing happens. Literally nothing - no dialog opens, no error message is displayed. If I have the Debug window open, no message are displayed.
If I go to Preferences -> Install/Update -> Available Software Sites, that dialog opens OK, I can manage the list of update sites, and test the connections, and they all appear OK. But I cannot get to use them to actually install anything.
Is it just broken, or could there be something more subtle wrong?
Thanks.
Start by checking you error log under Window -> Show View -> Error Log. See if you're getting any exception while trying to install new software.
You can also install by downloading the plugin and unzipping it in the dropins folder.
I ran into the same problem. There seems to be a bug related to the finish button (I am assuming this is the same problem you are experiencing). The way I got around it is by clicking on the finish button (or next, or whichever button is not working for you) and press the 'Enter' key. It's annoying. Seems to be an issue with how Eclipse is integrating with GTK.
I had the same problem, took a look at the error log and changed the launcher from "/usr/bin/eclipse" to "sudo /usr/bin/eclipse", it was a permissions thing...
GDK_NATIVE_WINDOWS=true also solved the non-clickable button problem for me running gnome 2.28.1 with Ubuntu Karmic (9.10) x64 with kernel 2.6.31-14-generic
To resolve this problem, I did the following:
Placed my copy of Eclipse in the trash
Emptied my trash
Rebooted my computer
Downloaded the latest version of Eclipse (which was Indigo at the time of writing)
Placed the .zip file in my applications folder
Double-clicked on the compressed zip to open it (I'm using Mac OS X.6)
The problem disappeared. I am now able to do Help/Install new software....
I suggest to use Eclipse Indigo (Eclipse 3.7) which contains EGit already.
Something you can try:
Delete (rename/move) your workspace and try again. Be sure to backup all your projects and settings.
Download the plugin "manually" and use Eclipse>Window>Preferences>Install/Update>Available Software Sites to add it locally.
Download the plugin "manually" and use Eclipse>Window>Help>Software Updates>Available Software>Add site>Archive, find the directory on your HDD and add it.
I had the same problem in windows... and spent couple of hours to "somehow" install the new softwares.
Anyway I will explain you how I managed to install it after trying many options..
Start a fresh copy of eclipse
First tick two check boxes(Show only latest version & Contact all update sites). Make sure the check box of group items is untick.
Try to add software...
If not showing the list of plugins/Next buttons.
Delete the copy of eclipse.
Start a fresh copy of eclipse
Tick only the check box for Contact all update sites.
Now try to add plugins. It worked for me...
Even if it sounds crap... it worked for me..
If none of the solutions above work for you, simply change the workspace to another location. If the list of items appears properly then there's probably something screwed up in the workspace and not Eclipse. Hope this helps.
I actually just had a similar problem and wanted to offer the solution that worked for me. This was not a permissions thing. To solve that I always install eclipse as my user in my local directory (e.g. /home/[user]/local/eclipse-3.7.2) and then you never have permission issues.
Setup: Go to Help -> Install New software -> Available Software Sites (to add new site)
Symptom: Try to add a new site. After hitting enter or clicking finish the site shows up in the list of available sites. Click Okay to go back to the install new software and the site is not available in the drop down. Go back to Available sites and the site is gone.
Fix: After adding the site click on the reload button while the new site is highlighted (before clicking Ok to go back to the "Install new software screen"
This was occurring on Indigo SR2 (and has been happening for a while). I am running this on Linux Gtk -- but I don't see why this would be related.
Hope this helps!
Delete your ~/.eclipse folder and restart eclipse. This is the only thing that worked for me.
I had the exact the same problem. What I found out is that I installed the eclipse as root user. Therefore, I need to be a root user in order to launch "Install New Software".
just press enter after entering URL in "Install new software" window
I faced similar issue. To troubleshoot this issue follow these steps:
Go to windows -> show view -> error.
Check the error logs. In my case error was java.lang.IllegalStateException: Registry Directory not available. at org.eclipse.equinox.internal.p2.engine.SimpleProfileRegistry.restore
I checked my config.ini which is under eclipse -> configuration folder.
I found eclipse.p2.data.area has incorrect path set.
I set the correct path for above key and restarted eclipse. It started working.
Hope it helps
I have faced the same issue. To solve the problem, follow the following steps:
Window (Eclipse Menu) -> Show View -> Error Log
if Error Log is not there, then:
Window (Menu) -> Show View -> Other -> General -> Error Log
Once the Error log is shown, Go to Help (Eclipse Menu) -> Install New Software
Check the Error log, most probable you will see an exception there.
Check the exception, most probable it's caused by java.lang.IllegalStateException
Check the path mentioned in the exception, if you see ".Lock" in the path, close the eclipse then go to the path in windows machine and delete that folder.
now go to the eclipse "exe" file that you're using and open it as an administrator, then try, most probably this will solve the issue.
I`m wondering if this help you.
Let me know if you have any queries.
I'm running Eclipse Europa (3.3). I leave the "Build Automatically" setting, under the Project menu, on all the time. Once in awhile my code isn't compiling, and I puzzle over it and then pull down the Project menu ... lo and behold, it's not set anymore. What gives? Is this a bug, or is there something else I'm doing that could cause it?
Edit: I am running the regular Java developer installation, plus Subversive and its connectors, Jetty Launcher, and I believe no other plugins. Other people at my workplace have had the same problem.
Edit: I am still having this problem once in a blue moon, only now I'm using Eclipse Galileo (3.5) for Windows. I haven't had this problem in Galileo for OS X, neither in Cocoa nor Carbon, but I have not used that for as long.
With Eclipise Mars.1 (4.5.1), Oomph may be the culprit. Eclipse Oomph supports automatically disabling Build Automatically with entries in
On Windows
%USERPROFILE%\.eclipse\org.eclipse.oomph.setup\setups\user.setup
If you want to disable this Oomph behavior try deleting the following setting
"Eclipse->Navigate Menu-> Open Setup menu entry-> Open User menu entry", a Preference Task under "User Preferences -> org.eclipse.core.resources -> description.autobuilding"
I learned about this setting by posting to the Oomph Eclipse Community Forum on Feb 8th, 2016. I posted a question titled "Oomph Defect? Build Automatically Keeps Getting Disabled". Ed Marks replied the same day with details about Oomph's support for managing the Eclipse "Build Automatically" setting.
https://www.eclipse.org/forums/index.php/m/1722751/#msg_1722751
I don't have eclipse right here to test and make sure but here is an idea.
Is any of the project or even workspace file in SVN ? if they are and they were uploaded with auto build disabled that might explain it
You update and overwrite your settings. This doesn't become apparent until you restart eclipse. this would also explain why other people at your workplace experienc this. it would even explain why some don't : thay are the ones who are careful what they update and don't allow eclipse to overwrite their own settings plus the ones who actually prefer to have autobuild disabled :)
I had the same problem and when I looked at the Source tab under Java Build Path (under the menu Project > Properties ) there were some source directories that didn't exist anymore (marked with a red X). After I deleted them, compilation worked fine and all new .class files are under the bin folder.
Strange. Is there perhaps a plugin installed that turns this off without your knowledge?
Maybe there is some conflicting shortcut. For example, some duplicated shortcut may be toggling it.
I am running 3.4 and I also have this mysterious behavior. I had it in 3.3 as well. I use CVS not SVN. Does not seem to follow a pattern just once in a while it gets switched off and then weird confusing stuff happens until I remember to check it and switch it back on. I am almost to the point where I want to write a plugin to always turn it on when eclipse loads.
When installing Google Plugin for Eclipse, 'Google App Engine for Android' is also installed.
For me, I uninstalled 'Google App Engine for Android', which I didn't need, and solved this problem.
