Eclipse plugin install error

Question

I'm trying to install the google plugin for eclipse but the installer keeps telling me :

An error occurred during the org.eclipse.equinox.internal.p2.engine.phases.CheckTrust phase

I've tried firstly to install from internet but then canceled it because of the poor speed. Then I download it and tried to install locally, then I have this problem. I'm using Eclipse 3.7.1 and the google plugin is also for version 3.7.

I've tried also to clean up the configuration folder by deleting anythings has the name equinox but that's no use.

Any suggestions? Thanks!

Here goes the error log:

Answer 1

Ok, I think it's a failure inside Eclipse. Now I've downloaded a clean one and the installation was all ok.

Looks like you're missing a file with the given name. (com.google.appengine.eclipse.core_2.5.1.v201201120043-rel-r37.jar) Try searching for it using your favorite search engine and placing it manually in the specified location. (/home/darkjh/eclipse/plugins/)
