Patch Set 1:

these build problems were caused by a failed download of the findbugs-maven-plugin, by default Maven will not retry the download. This can be fixed by either wiping the workspace (means .m2 repository) or by using the -U command line parameter which will enforce retrying the download on the next build. I reconfigure the egit build to use this -U option.

Now we run into test problems since the egit.core tests seem not to be able to find the mockito jars, I am currently investigating why.
