andromda*-3.4-SNAPSHOT-sources.jar files contain no source or resource artifacts, only the pom.xml file. I debugged through the maven-source plugin, trying multiple configurations (resources, includedFiles, etc). Each time, the proper values were fed into the maven-archiver dependency classes, but nothing was output.
For sync to maven central repository after release, we must include the sources and javadoc jar files.
Andromda 3.4-SNAPSHOT as of 8/2/10
