I have seen that all eclipse plugins in FC24 are installed in /usr/share/eclipse/droplets but eclipse-finbugs is installed under /usr/share/eclipse/dropins and I guess that could the root of the problem

Thanks for the report. Indeed I think the use of droplets is the problem. If I start Eclipse with debugging turned on, I see:

The JDT plugins are in the droplets folder:

This page:

http://wiki.eclipse.org/Equinox/p2/P2_Fragments

says:

P2 director WILL NOT BE ABLE to install things that are in the fragments. This is a limiation of runnable repositories mechanism (so if you have a bunle named a_1.0.0.jar, installed via a fragment, you will not be able to install any a_1.0.0.jar using that installation director.

which I think is saying that plugins in the dropins folder (like FindBugs) can't depend on plugins in the droplets folder (like JDT plugins).

Yes, the fix would be to move findbugs to droplets.

Building right now: http://koji.fedoraproject.org/koji/taskinfo?taskID=14898640

The F24 build has finished (http://koji.fedoraproject.org/koji/taskinfo?taskID=14898640) so could install the new package from there. I also need to update eclipse-findbugs-contrib before submitting an update for F24.

findbugs-contrib-6.6.1-2.fc24 eclipse-findbugs-3.0.1-7.fc24 has been submitted as an update to Fedora 24. https://bodhi.fedoraproject.org/updates/FEDORA-2016-43cd70e410

I downloaded the rpm and tested it and works fine. Thanks for the fast support

You're welcome! Can I check one thing though - do some of the icons in the FindBugs views show up as red blocks for you?

eclipse-findbugs-3.0.1-7.fc24, findbugs-contrib-6.6.1-2.fc24 has been pushed to the Fedora 24 testing repository. If problems still persist, please make note of it in this bug report.

It is true what you mention that some of the icons in the findbugs are shown as red blocks instead of using the normal icons

Thanks for confirming. I just wanted to check it's the same for you as it is for me. I don't think the functionality is affected by this though. I'll get the icons fixed in a subsequent update.
