I've only used Scala briefly (and then sbt fulfilled my meager needs) but from the rants by people I follow, each one of them shifted between sbt and mvn every 1-n releases over the years, because the one they were currently using annoyed them too much. Then again I guess this goes hand in hand with the old criticism that the various releases are not backwards compatible.
