   * known limitations are notably that:

     1. plugin goal execution in a child is usually simply appended (at end): you can't try to insert in the middle of pre-existing inherited executions,

     2. append happens at plugin level first, then goal level, independently from phases.
        This means for example that adding pluginA:goal2 to pre-existing (pluginA:goal1, pluginB:goal) will lead to (pluginA:goal1, pluginA:goal2, pluginB:goal)

 Notice that before Maven 3.1.0, with logger created by Maven, some code used to pass logger from class to class because it could not create a new logger:

 the project level, and the user level. On the site level you can configure maven for all users
