Fair enough, my mis-understanding - I thought you were talking about
the whole remote-resources config rather than just the version in
plugin management. To be honest the main reason I didn't want to put
it back at that time was that it was during the vote for
commons-parent-6 and I didn't want it held up for something that I
believe we had decided not to use. I guess the fact that I screwed up
that release makes it quite funny.

But thats not what happened with remote-resources which you put into
commons-parent - which caused duplicate LICENSE and NOTICE files and
garbage in the NOTICE file. I've tested this change on commons Chain,
both with the normal setup and by deleting the NOTICE/LICENSE file and
configuring the remote-resources plugin. Both worked OK. I think we
should put it in - if down the road a problem appears then fixing it
and doing a release is not that big a deal.

So at the moment three people (Jochen, Rahul and myself) think it
should go in and one (Dennis) is against - I'll leave it a while for
other opinions, but if the majority agree then I'll commit it.

Despite all recent argument, it is appreciated and I hope I haven't
upset you too much.

I assume your talking about removing the ".txt" extensions from the
NOTICE and LICENSE files. Firstly at least some of us think its more
(windows) user-friendly to keep them. Secondly using Validator as an
example - it currently has three working build systems - ant, m1 and
m2 - so renaming the files to make m2 more easily means fixing the ant
and m1 builds as well - and correcting at least one other build is
going to apply to most other components as well, unless we wait until
all are on m2. I think we need working m2 builds to encourage
components to make the switch (and I've done quite a bit to help with
that) and so a less invassive solution is needed which I proposed in
MRRESOURCES-31. Its not maven were working against with this issue -
its the apache-jar-resource-bundle. I believe that if the maven team
does MRRESOURCES-31 and the dependencies meta-data (i.e. poms) get
fixed so the contents of the NOTICE file are good - then I think you'd
have a better chance of persuading commons to adopt remote-resources.
It doesn't then leave much argument against using it - or at least
making it available in commons parent.
