Hi p2 developers, this is a rough follow-up on a problem I encountered 2015 [1], but didn't receive a reply yet. Then, I abandoned my attempts to use p2ql expressions to allow automatic updates after a rename, but now I have the need again for a different project (SpotBugs, a FindBugs fork).
The problem is this: I have a p2ql expression [2] that is meant to upgrade older versions of FindBugs and SpotBugs: update.matchExp = providedCapabilities.exists(iu | iu.namespace == 'org.eclipse.equinox.p2.iu' && ((iu.name == '@FEATURE_ID@' && iu.version ~= range('[0,@FEATURE_VERSION@)')) || \ (iu.name == 'edu.umd.cs.findbugs.plugin.eclipse.feature.group' && iu.version ~= range('[0,3.0.3)')))) Interestingly, upgrading older versions of FindBugs to SpotBugs works, but updating older versions of SpotBugs to newer versions does *not* (at least not with "Check for Updates"). I have to manually install it. If I do, however, p2 *is* capable of figuring out that this is indeed an udate: > Your original request has been modified. > "SpotBugs" is already installed, so an update will be performed > instead. Can someone enlighten me what I am doing wrong here?
