[xwiki-devs] m2eclipse and xwiki-commons

Hello devs, I just finished porting my XWiki development environment from Windows 7 to Ubuntu 12.04. I am now able to build all projects from the command line without errors. I'm working with the master branch from Git. I have Eclipse Juno installed with plugins that include m2eclipse (the version from the Eclipse update site) and AJDT. I am now trying to import the entire xwiki-commons Maven project into Eclipse. Just as happened under Windows (which I never asked about, since I was still trying to get command line builds to work), there are three Maven goals (plugins) in the xwiki-commons projects that fail to map to Eclipse plugins -- aspectJ-maven-plugin, maven-antrun-plugin, and maven-remote-resources-plugin. Can anyone give me some hints on how to resolve these mapping problems? Googling for answers about this hasn't yielded anything that I can understand :-) --Gary
