I'm using the J2EE bundle of Eclipse Kepler, and I'm working with Git.
I'm also using git-extension as a UI to git, and I wouldn't trade it for anything else, so for me egit is just an annoyance that brings information that I don't want on my screen.
How can I permanently remove it from eclispe ?
It's easiest to just disable EGIT from automatically managing your projects at import via Window - Preferences - Team - Git - Projects:
This will stop new projects from being managed, but projects that were imported before the change will still need EGIT to be disabled manually for the project. You can just right click -> Team -> Disconnect and they will no longer be managed by EGIT.
