Build Identifier: I20080617-2000

After I installed subclipse plug in 1.6, on my eclipse ganymede version 3.4.0 on my suse linux enterprise desktop 11, I can not uninstall the subclipse plugin nor can I install another plugin. I cannot even add projects to the eclipse environment !

The only thing that works now, is that I can run eclipse IDE, but nothing works after that. Whatever I do, I get the same error "Nullpointer Exception error" ... The error log file is given below:

Reproducible: Always

Steps to Reproduce:
1. Uninstall Subclipse.
2. Install some other plugin.

Which Eclipse download did you get? What is the name of the file?

Comment 2 Prakash Rangaraj

Does Subclipse 1.6 is supported on Eclipse 3.4?

Comment 3 Thomas Hallgren

Subclipse supports Eclipse 3.2+ according to their download page at http://subclipse.tigris.org,

I got the eclipse available from the opensuse repository for opensuse 11.3. It is eclipse 3.4.0 (ganymede).

Even if it is not supported, it should still be uninstall-able from the eclipse plugins. I guess.   :)

We no longer provide support for 3.4.x
