This is due to two separate issues. The first is that the plugin expression
evaluator wasn't processing command line properties first and there is a field
in the help plugin called "plugin" which interferes with the field in the
plugin descriptor configuratino called "plugin". The command line was being
processed first so this wasn't a problem anymore. The plugin plugin should
block field names/setters that are the same as elements in the default plugin
descriptor.
The second problem is that the plugin manager and lifecycle executor have been
changed so much that most of the methods the help plugin needs are no longer
there. The help:describe mojo is a chunk of core logic in a plugin. Something
like this could probably be way smaller and in the embedder which would be
useful to IDE integration pieces.
