Trouble updating Eclipse plugins

Question

I just installed some extra repos and now I'm trying to Check for Updates but I keep getting an error that I can't seem to get past and can find nothing about it in the google.

Cannot complete the install because one or more required items could not be found.
Software being installed: EGit Mylyn 1.3.0.201202151440-r (org.eclipse.egit.mylyn.feature.group 1.3.0.201202151440-r)
Missing requirement: EGit Mylyn 1.3.0.201202151440-r (org.eclipse.egit.mylyn.feature.group 1.3.0.201202151440-r) requires 'org.eclipse.mylyn.team_feature.feature.group 3.5.0' but it could not be found

I'm at a bit of a loss here. Anyone know how to fix this?

Answer 1

You are missing a Mylyn feature. Make sure you have the Mylyn update site in your list of software update sites and you should be good.

Answer 2

I had similar issues with Mylyn in the past that could only be solved by first uninstalling all Mylyn plugins, then updating the remaining plugins and installing all Mylyn plugins again (which is okay, as your settings remain the same).

@Francis: And that was not caused by missing update sites. I think the underlying issue is more that most Mylyn connectors use a very narrow version range for their "host" plugins and updating a "mixture" of different Mylyn connectors then can get P2 into believing that the update cannot be done, although just updating all to the latest version is a valid solution. Not sure whether to blame Mylyn or P2 then...
