Question

Introduction: I asked this question on the P2-forum already but I couldnt get any answer yet and this question is very important to me since it is blocking my work completely

I am in the need of patching the current Mylyn-Context.Core Feature, so I checked out the plugin org.eclipse.mylyn.context.core (3.6.1), created a fix and updated the version to 3.6.2.
Afterwards I created a feature-patch project which patches org.eclipse.mylyn.context_feature in version 3.6.1.v20110728-0200.
I added my patched plugin to the dependencies of the feature.

When I export a p2-repository (inlcuding the feature with the plugin that needs the patch) I get a folderstructure that looks correct. All features and plugins are there with the right version.

When I am installing the patch, P2 doesn’t complain about missing requirements and installs without errors.

Now the problem is that within the plugins folder of eclipse there is only org.eclipse.mylyn.context.core in version 3.6.1…. but not 3.6.2 hence my plugin isnt working.
The strange part is, that the patch-feature is installed but it doesnt complain about a missing bundle (the patched 3.6.2).

I compared the contents.xml to a patch from the Oracle OEPE Tools and it looks like everything is correct.

Can someone help me out here. I am trying to fix this since two weeks without getting any step further.

Thanks in advance
Marc

P.S. I added the generated content.xml from the generated P2-Repository

Answer 1

Found the same issue from bugzilla.

In a word, you are trying to patch a feature not including the plug-in. You should patch “org.eclipse.mylyn_feature”.
