[cstamas]

And do align them. Max Level is Java 8, but
we had several conflicts, like HttpClient
(used by Wagon but also by Resolver-Transport-Http).

@michael-o on JIRA you mention "Commons CLI must not be touched because the upgrade requires also code changes. See master.". What code changes you mean here?

I found this 4476026 but here parser is changed. Is it necessary? GnuParser is already deprecated (was in 1.3), but imho does not require code change, or I miss somethin?

The migration introduces a slight incompat problem. That is why we did not touch it in 3.x. The previous impl was ugly, now I'd say that it is correct.

@michael-o so this PR is okay?

Yes, this is OK, if all ITs pass and if it is a sole CLI update w/o back porting the code from master. Honestly, I would back port the code from master with a separate issue.

@michael-o so you approve it?
