For interrested readers, you can get background information about this Maven's choice on Sonatype blog [1]. I've been thinking on something similar for a while but didn't find time to write down a plan / implement it. So, I think you're right Torsten : this is the path to follow. One thing we have to handle carefully is behavior difference form upstream Maven binary release : - right now, in Debian, Maven 2 is using a different set of version plugins than upstream Maven 2 tarball so it cause confusion to user - maybe we'll have to provide multiple version of core plugins ? just to ensure we stay compat with upstream... - Maven 3 will be be better on this by setting less plugin in super-pom and forcing user to explicitly set plugins version in its pom So, regarding Maven 3, there is less static version inside super-pom [2] except for some important plugins of default lifecycle [3]. Maven 3 compatibility-notes explicitly : "Given the threat of non-reproducible builds imposed by automatic plugin version resolution, this feature is scheduled for removal as far as plugin declarations in the POM are concerned. Users of Maven 3.x will find it output a warning when missing plugin versions are detected to encourage the addition of plugin versions to the POM or one of its parent POMs. The Enforcer rule requirePluginVersions can be used additionally check for missing plugin versions in the POM."
