Hi Erlend, that problem depends on some issues about filtering of the Maven Eclipse Plugin that are introduced with the latest versions. Infact in the 2.6 version there is no problem.
Now I think that this plugin could be considered deprecated. We are waiting for the new version that should have all these issues solved but I don't know when it will be released. There are many other projects in the world that exactly have the same problem. I suggest to use the m2Eclipse plugin directly inside Eclipse IDE without invoking the mvn eclipse:eclipse command. m2Eclipse is the most updated plugin with all the these issues solved. I don't use Maven Eclipse Plugin for a long time because I never need to use it. Hope this helps.
