Problem starting Eclipse

[prady]

Hi All,

I am having trouble starting Eclipse. It was working fine until last week I tried installing a plug-in. I get following message every time I try to start Eclipse- "An error has occurred. See the log file /home/user/workspace/.metadata/.log."

Following are contents of the log file.

!ENTRY org.eclipse.core.resources 2 10035 2009-03-26 17:20:01.894

I have already wasted quite a lot of time on this. I have tried apt-get purge to remove all and re install everything. I have tried reinstalling JDK and JRE. I have tried starting eclipse with sudo. Nothing seems to work. Anyone has any suggestions?

Thanks in advance!

It looks as if Eclipse has lost track of some resources in your existing workspace. Try (from a command line):
eclipse -clean

If that doesn't work, you might be able to close all open windows, close all perspectives, save & exit and restart.

If that fails, try creating a new workspace and bringing your work in.

Thank you for replying.. and well. I am stumped. eclipse -clean worked the first time I tried it. I looked up the command and found this page

http://www.eclipsezone.com/eclipse/forums/t61566.html

I changed my eclipse.ini , eclipse won't start. I decided to revert the changes and provide clean argument every time I want to start the program. Now even that does not work.

I think you have a hang of what is happening here.. Can you think of why the reverted changes won't work? What can be done to correct it?
