Fixing LICENCE and NOTICE for binary distributions
as Vladimir reported in  we have problems of our binary distributions.
Short version of the story:
- we are missing some entries in LICENSE, in my opinion we should cite
every other ASLv2 licenced project that is not of property of ASF (like
Plexus), but we are currently skipping them
- we are not handling correctly some hidden (shaded/relocated) dependencies
- some of our direct dependencies of Maven Core messed with their LICENSE,
so the data that we can download automatically (from Maven central) is not
consistent with other sources (websites for instance)
Please follow up on JIRA for the detailed discussion about every single
I have also started a branch for the fixes, but it is only a playground for
me currently as we should decide how the LICENSE/NOTICE/.license files
should look like before actually doing this.
I have experience of this kind of discussions in Apache BookKeeper project
and we came out with this doc  and a Pull request validation script that
validates as much as possible those rules.
I am tyring to understand our dependencies and our packaging of licensing
material, in order to come with a complete proposal.
