GWT compilation failed

Question

I am developping a GWT Application and when I was about to compile I got a message "GWT Compilation Failed" without any stacktrace.

Then I've tried something even simpler, like creating the sample application and I've got "Creation of element failed. Reason: Invocation of com.google.gwt.user.tools.WebAppCreator failed".

I did a lot of research and tried a lot of stuff (change folder permissions, deactivate antivirus, changed version of eclipse and gwt, checked windows event logger (found nothing), recreate workspace, remove ClassPath environment variavble...). The most weird thing is that in my personal computer everything works fine, but copying the eclipse folder to my work's computer I get always the same problems.

This is the .log from eclipse.

Does anyone has any ideas about how to fix this?

Please try it again after removing all the generated stub and re-compiling the project again. — Braj
I tried jdk1.6.0_45, jdk1.7.0_51, jdk1.7.0_55, jdk1.8.0_05 and none of them worked. The problem is certainly deeper. Especially because jdk1.8.0_05 and jdk1.7.0_51 works in my personal computer. Another weird thing is that it works if I execute by cmd. — Gigi
Moreover, there is no generated stub. It does not generate anything, for any project (new or old). — Gigi
How did you imported the project into Eclipse. Use Import functionally of Eclipse. — Braj

I removed ClassPath entry from Windows Environment Variables and it did the trick.
