Unable to install EGit plugin on Eclipe Helios
EGit 2.2 requires Eclipse 3.7 or greater, see "What versions of Eclipse does EGit target?" in the FAQ.
If you don't want to upgrade to Eclipse 3.7 or greater yet, you can still install EGit 2.1 from the following update site:
http://download.eclipse.org/egit/updates-2.1
When I use Helios I hava the same problem,Because of the version can't mathch, You can try installing it through the 1.0 version:
http://download.eclipse.org/egit/updates-1.0
It works!
PS:Indigo can work with http://download.eclipse.org/egit/updates-1.3
Engory yourself...
Try installing it through the Helios update site:
http://download.eclipse.org/releases/helios/
It should reference all plugins including EGit.
That being said, robinst's answer (upvoted) points out to a dependency to Indigo (3.7), which could mean Helios (3.6) isn't supported.
