View Full Version : Eclipse startup error - solved.

February 6th, 2008, 12:06 AM
Just wanted to share the solution for a nasty Eclipse error that I had today.

env: Eclipse 3.2, with Pydev, on Ubuntu 7.10, using the java 6 jvm.

Eclipse would fail at startup and advise me to look my workspace/.medata/.log file.

org.eclipse.core.internal.dtree.ObjectNotFoundExce ption: Tree element

This was in relation to one of my source files which was on the file system allright. I tried to move my source file elsewhere but that didn't help.

There was an IBM solution talking about deleting workbench.xml. That didn't help either.

Looking around some more I found a solution at http://forum.ubuntu-fr.org/viewtopic.php?id=183842

which advises to delete the .metadata directory.

I deleted both


and the problem went away. So did my pydev projects though.

I had to reconfigure pydev first. Then I created projects with the same names as previously and I unchecked the 'create default src directory' checkbox each time.

I got all my projects back, including the SVN info. But I did lose any extra configuration at the project and PyDev level.
