List the versions of eclipse and plugins used for anyone else who is insteresting in this.
Eclipse 3.6 Helios Service Release 2
Eclipse JGit 0.11.3 -- EGit -- http://download.eclipse.org/egit/updates
A pretty good article for EGit http://www.vogella.de/articles/EGit/article.html

setup the maven home, setting files and local maven repository.
