I recently (this morning, 2/19/09) checked out a clean copy of the source from the trunk. Although using maven from the command line built everything fine (I needed to include -U,) importing into Eclipse has problems that I believe are related to this error displayed in the "console" of eclipse.
2/19/09 10:35:09 AM EST: Build errors for sling-builder; org.apache.maven.lifecycle.LifecycleExecutionException: Internal error in the plugin manager executing goal 'org.apache.felix:maven-scr-plugin:1.0.8:scr': Mojo execution failed. Has anyone else seen this or something similar? I'm using Eclipse: Version: 3.4.0 Build id: I20080617-2000 (which is Ganymede) on ubuntu linux with jdk 1.6 installed. It's worth nothing that there are several other errors, that may be rooted in the confusion between which version of org.osgi.framework.Constants to use. Specifically eclipse has problems when compiling org.apache.sling.launchpad.base.impl.Sling.java in the launchpad base project. Furthermore, scala scripting really seems to "fall off the curve", but I haven't explored if this is related to the other problems. However, this all seems to be related to Eclipse as: % mvn -U clean install at the top level of the trunk works fine. -- Langley
