Eclipse hangs on reverting resources

Question

I use eclipse Indigo, subclipse 1.10.x and javaNL. Whenever I try to refresh my project in eclipse, it gets stuck at Reverting Resources 0% and Computing Update Requirements 0%. I try to kill eclipse and reopen the project and it still does the same. I do not understand why this happens. It started happening recently. Before it was working fine.

Answer 1

Question: I do not understand why this happens

General Answer: http://www.ihateeclipse.com/

(I may share this opinions and dont think Eclipse should be called a IDE but that wont fix your problem - hence lets proceed with possible workarounds).

Possible Workarounds:

1.) Starting eclipse in clean mode How to run eclipse in clean mode? and what happens if we do so?. (This solved aprox. 80% of my continuously returning 'I messed up my own state' issues I experienced).

2.) If that doesnt help - you would have to stop eclipse, identify the according files (or just any files holding such information) and delete them manually, then restart eclipse. Like I still encounter issues with my "Search Type" (Ctrl+T) and have to delete the files like described here Eclipse type hierarchy not always working (unfortunately I don't know anything about files regarding your current issue - so feel free to downvote my "answer" since its not directly answering your question).

The best things I found about "the full reset" seem to be: http://letsgetdugg.com/2009/04/19/recovering-a-corrupt-eclipse-workspace/ or http://blog.pdark.de/2011/09/02/restoring-a-corrupted-workspace-in-eclipse/ (Note: I haven't verified the described behaviors).

3.) Recreate Workspace - delete any eclipse belongings like the .metadata folder and keep only belongings of your project (e.g. sources, resources etc.). Then create a new eclipse project based on you existing project sources).

4.) If Steps 1-3 failed consider reinstalling Eclipse (include above Step 3 in this process again) or switching to a proper IDE that can at least handle its own state.

5.) I experienced rare cases where in the end such things were triggered by me rather than occurred magically out of nowhere by eclipse - I don't see any possibility on how you could manage that in your case unless you messed around with the eclipse source itself).

Hope this helps - Even thus the SO community is big I experienced way better results asking the eclipse developer community directly when it came to such specific issues (you however oftenly get a link to a open Bug ... that they created because of your question) and ended up "just importing into a new eclipse workspace from existing sources" whenever I experienced such issues lately (It takes me about 5 minutes to checkout our sources, start Eclipse with -clean as default and import existing Maven projects solving any eclipse-only issue - while each of those eclipse-issues can take days to be solved without any further advantage for my daily business)

Answer 2

I don't know if this will help any one but I had the same issue. Some links advised me to delete my metadata, which I did not want to do.

What fixed it for me was:

1. I have multiple eclipse workspaces, I manually closed my eclipse using the System Monitor/Taskbar as it wouldn't let me close as it was hanging.
2. I switched workspaces and it seems to run fine. So I switched back to the one that was hanging and the problem seemed to have gone.

Answer 3

this helped me: delete files "*.snap" under org.eclipse.core.resources in worskpace/.metadata/.plugins/org.eclipse.core.resources/

and share project again (setup SVN settings)

Answer 4

I accidentally checked in target files to SVN. And the target files were huge ans hence it was stuck on reverting resources. Once I deleted those target files from SVN this issue never happened.But JBA's answer is pretty comprehensive so I will mark that as a right answer.

Answer 5

This should work to 100% and helped in my case (no other tried solution worked):

1. Go to "Eclipse > Help > About Eclipse IDE > Installation Details

2. Uninstall the following packages "Subclipse", "Subclipse Integration for Mylyn", "Subversion 1.14 JavaHL", "Subversion Revision Graph", "SVN Client Adapter". pluginsToUninstall

3. Go to the marketplace and install "subclipse" again.

4. Rightclick on your project > Team > Refresh/Cleanup

You are welcome. :)

Answer 6

This worked for me: Go to to your workspace instalation, and manually delete the target directory under your maven projects (dont worry , maven will create another one when compiling). This removed my stuck Eclipse state (thread) in "Revert sources", always at 0%.

Answer 7

I have this same issue, and I just quickly cancel the "Rerverting Resources" task while it's in "waiting" mode when restart Eclipse.
