[MNG-6135] Maven plugins and core extensions are not dependencies, they should be resolved the same way as projects.

**[Christian Schulte](https://issues.apache.org/jira/secure/ViewProfile.jspa?name=schulte77)** opened **[MNG-6135](https://issues.apache.org/jira/browse/MNG-6135?redirect=false)** and commented

Due to a bug in the Maven resolver, plugin and core extensions were resolved incorrectly: the direct `test` and `provided` dependencies were ignored.

Ironically, this fix breaks some plugins because direct `test` dependencies now take precedence over transitive `compile` one: see MNG-5739
(we know only one case where `provided` case has an impact: MPLUGIN-296, and in this only case, the new behaviour is more consistent than the previous)
