This is kind of a weird question so bear with me.
I found a way to allow unlimited output in the 'debug shell' view and then I executed a function in the Eclipse "debug shell" (used to be known as 'display') and it produced an output so large that it breaks my Eclipse. This forced me to reboot eclipse. Unfortunately, now everytime I open Eclipse it tries to open that view again, and so my eclipse is sort of permanently broken. Is there a settings file I can go into somewhere and dump so that it doesn't keep trying to load that garbage everytime I boot Eclipse?
Thanks
The answer lies somewhere in the eclipse .metadata directory (at the root of your workspace). I closed my eclipse, deleted this directory, and then restarted my Eclipse and was able to open up the debug shell again. Keep in mind this will delete all your Eclipse settings and have to restart from scratch again, however its worth it for me because I have to have this debug shell.

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.
I have this weird issue where the following happens:
fresh eclipse juno install (with all updates applied)
works fine for a while asking which workspace I want to open with a dialog on startup
after a few days it stops prompting me for workspace, opens blank made up workspace instead in /Users/myself/Documents
If I check "preferences -> workspace -> startup and shutdown" everything seems fine, the only workspace in the list is the one I created and the checkbox that says "don't prompt for workspace" is not checked.
This happened a few times already on fresh eclipse installations and fresh hard drives (same machine but I replaced the hard drive, re-installed OS and everything for other reasons and now it happened again).
I am on:
OSX 10.7.5
Eclipse Juno (Service release 2)
Any help appreciated!
I have exactly the same problem on OSX, for no reason, one fine day, Eclipse will start-up with a new blank workspace!
And to all the stupid answers and responders out there: YES I know how to set and select a default workspace! And NO creating a new workspace, re-importing lots of projects and loosing all my 30+ database connections under my Toad Extension, is not an option.
What I found is that
For some reason Eclipse creates a directory /Users/user_name/Documents/workspace which is the blank workspace it starts-up with (incorrectly)
My usual workspace is under /Users/user_name/Documents/Development/eclipse
The solution is (this is on Mac OSX, don't know if it is the same on Windows):
Goto your Eclipse directory where you run Eclipse from (mine is /Applications/eclipse)
In {eclipse_dir}/configuration open the file config.ini
Find the line osgi.instance.area.default=#user.home/... and confirm that it is pointing to the bogus workspace directory.
Modify the path of this entry to point to the correct workspace
Save the config.ini file.
Try starting Eclipse and it should open your workspace now.
If your Eclipse get stuck loading plugins now, goto your workspace directory and look for the .metadata directory (its hidden). Inside the .metadata directory, remove the .mylyn directory and restart Eclipse.
Once Eclipse started with the correct workspace loaded, do a proper Eclipse shutdown to ensure your workspace is closed and saved properly.
This worked for Eclipse Juno.
Hope this helps!
Just running this command helped me
eclipse.exe -data C:\Development\Eclipse\Workspace
FYI this happens due to install of some plugins.
This same problem happened to me on Windows on two separate Eclipse installations, without installing any plugin.
I was able to get my working Workspace by clicking on File > Switch Workspace, but closing and opening Eclipse again would reset it to a default Workspace.
What apparently solved this was to force Eclipse to save Workspace settings by ticking the Prompt for workspace on startup setting in General > Startup and Shutdown > Workspaces, which I had turned off.
The next time Eclipse opened, it asked me for the Workspace, and it had my correct one first in the list. I asked not to be prompted again for it and now it opens the right workspace when I launch Eclipse once again.
I solved this problem as per JJ-za's answer, except steps 2 and 3:
In {eclipse_dir}/configuration/.settings open the file org.eclipse.ui.ide.prefs (when Eclipse is not running)
Find the line RECENT_WORKSPACES= and confirm that the workspace is pointing to the correct workspace directory and that multiple workspaces are separated by \n
Right now I'm having this issue in Eclipse where I have an XML file open that's really big in which it almost crashes Eclipse. However this file being opened is saved in my window history, therefore I restart eclipse, it tries to open this massive file again. How do I clear the opened window history in eclipse?
I would prefer not having to clear my workspace entirely as I have mylyn data I want to keep. I've tried using Eclipse clean but this doesn't seem to do anything related to opened windows.
Your workbench information are saved in this file in your workspace:
.metadata/.plugins/org.eclipse.ui.workbench/workbench.xml
or depending on your eclipse version:
.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi
You can delete it and eclipse will recreate the file, you can also try to edit it, but it's a big file and may be hard... Deleting this file all workbench related settings are lost but your projects stays intact.
Go to Preferences and search for 'workspace'. You will see the list of workspaces that you can delete.
Some alternatives:
Move or rename the offensive file so that eclipse is unable to open it.
File->Switch Workspace->Other to load a new workspace copying your workbench layout.
Just some thoughts, my experience is closing a file and then the program means that the program will not attempt to open the file once launched again.
Can anyone help me with this error:
java was started but returned exit code = -805306369
C:\Windows\System32\javaw.exe
-jar C:\Program Files\Java\eclipse-jee-helios-SR2-win32-x86_64\eclipse\plugins\org.eclipse.equinox.launcher_1.11.1.R36x_v20101122_1400.jar
Just had this issue, for me it was a corrupted workspace osgi cache. The solution was to run eclipse with the -clean parameter as
eclipse.exe -clean
After some time, eclipse required to clean up, the workspace selection dialog popped up and I could start eclipse normally again.
The -clean parameter is documented in the eclipse help
My problem was a corrupted workspace the solution was from Rob's link:
http://spacetech.dk/eclipse-failed-java-was-started-but-returned-exit-code-805306369.html
I started getting the same error "exit code = -805306369" just out of no where.
Eventually I looked at the Eclipse logs at the <workspace_directory>/.metadata/.log and realized that my Source Control plugin (Perforce in my case) was unable to connect and the eclipse was stuck.
This was because my eclipse was piggy back(depending) on the client connection that I have with my Perforce windows client and my Perforce client was not connected to the server. I connected my Perforce client and the eclipse started working normal.
this happens when mostly workspace is corrupted..... cooler solution is just to switch the workspace to safer location(new location).... and just import the project from previous workspace... princess can still be saved....
For me , Just change your Workspace to another one
I got this error, when workspace already setted up. Since the java virtual machine cannot be created. try command: java -version
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
I restarted my machine, and it solved my problem.
One of the class file in my project was corrupted. The name of a class file was too long and I was not able to delete or rename it, so I rename the folder containing it and then I was able to delete the project and that solved my problem.
Now i know that my workspace was corrupted, it solved my problem.
Go to your workspace and rename it.
Start your eclipse and by default it will create a workspace.
Go to File -> Switch Workspace, choose your original workspace.
I wasn't able to disable "Automatically find new updates and notify me." The option was not there on the Install/Updates page. Perhaps eclipse workbench has changed since that answer was written.
However, running eclipse with the -clean option in my old workspace did the trick for me. The way to do that in windows is to first find the directory where eclipse.exe lives. You can go to the start menu and in the "search menus and files" bar, type eclipse. You should see the purple globe icon pop up under "Programs." Hover your mouse over it and it will tell you the directory it exists in.
Then... open "computer" or some other window from the start menu and from there navigate to the window where eclipse is. Click your mouse in the bar at the top where the directory is displayed (somewhere not on the text). That directory will highlight. Now type cmd. A black command window will open and you will be in the directory where eclipse is. At the command prompt (drum roll) type eclipse.exe -clean
eclipse will start. Make sure it is asking to go to your corrupted workspace and click OK.
Wait for it and soon you will know if your workspace has been uncorrupted. Yay!
“java was started but returned exit code = -805306369” caused by Eclipse´s currupted workspace, I solved my problem with this 4 steps:
1) claose the eclipse.
2) Kill the adb from task manager.
3) Start your eclipse and by default it will create a workspace or start with new workspace.
4) Go to File -> Switch Workspace, choose your original workspace.
In my case, it is a work laptop, so pretty secure SOE
64 bit Win 7.
Unzipped Eclipse MARS onto a folder on "C" drive
Install failed consistently with Java error code -805306369
Created a separate folder on 'C' drive for workspace, granted
everyone full-control and that fixed it!!
I got same issue when opening files using shortcut - Ctrl+Shift+R.
I got it resolved by disabling "Automatic Updates".
Steps to disable automatic update in eclipse (helios): Windows >> Preference >> Install/Update >> Automatic Updates. Disable "Automatically find new updates and notify me".
How I managed to get mine working. I used a combination of the solutions above. It works for me.
Step 1: Change your workspace to some other names e.g. change it from workspace to workspace1.
Step 2: Access your eclipse and stop automatic updates (provided that you could access after changing your workspace)
Step 3: Exit your eclipse with workspace1
Step 4: Start your eclipse with former workspace by entering eclipse.exe -clean (if you are using others then use e.g. MuleStudio.exe -clean)
In conclusion, using a combination of solutions such as changing workspace, stop automatic updates and -clean work for me. Try it yourself.
Question: where does Eclipse store the list of files it opens on startup?
Background: Having installed a plugin into Eclipse which promptly crashed, my Eclipse workspace is in a bit of a state. When started, the building workspace task pauses indefinitely at 20%. Before I uninstall the plugin I want to give it another chance. I have a feeling that the reason Eclipse is pausing is because of a file which was opened when it crashed, which it tries to reopen on startup. If I can stop this file from opening on startup there's a chance I may be able to coax the plugin to behave. The problem is I have no idea where that list of files is persisted between runs of Eclipse.
...a second before I posted this question, I realised I could just delete the file causing the problem (duh). However, the search has frustrated me enough to want to find the answer.
In your workspace the following file contains your workbench information:
.metadata/.plugins/org.eclipse.ui.workbench/workbench.xml
It is possible to delete it (or edit it but that requires some fiddling around I suppose) without breaking your workspace, the file gets regenerated by Eclipse. When you delete it all workbench related settings are lost (ie all editors are closed), but your projects of that workspace stay intact.
Edit: in Eclipse 4.2 the file is
.metadata/.plugins/org.eclipse.e4.workbench/workbench.xmi
