I am getting this error when installing EGit:
Cannot complete the install because one or more required items could not be found. Software being installed: EGit Import Support 2.0.0.201206130900-r (org.eclipse.egit.import.feature.group 2.0.0.201206130900-r) Missing requirement: EGit Import Support 2.0.0.201206130900-r (org.eclipse.egit.import.feature.group 2.0.0.201206130900-r) requires 'org.eclipse.team.core 3.6.100' but it could not be found
I suppose it requires the base team module to be added to Eclipse but i cannot find the download.
The "EGit Import Support" feature requires Eclipse 3.8, 4.2 or higher. Just deselect the checkbox, and installing should work.
See here about the feature: http://wiki.eclipse.org/EGit/New_and_Noteworthy/2.0#Support_for_Eclipse-SourceReferences_manifest_headers
