[wildfly-dev] smaller footprints

I have made a start on this split, and I think the solution I am working
on will meet all the use cases, including users that want to cut down an
existing server, and users that want to re-use the jars in their maven
repo using Bill's changes to JBoss Modules. It still needs a bit more
work and a lot of cleanup, however it seems to work:
https://github.com/stuartwdouglas/wildfly/compare/wildfly-build-plugin
So basically the core of it is a maven plugin that builds a Wildfly
distribution, either from scratch or use other distributions as a base.
It also supports building servers that use the new <artifact>
functionality in jboss modules, and cutting down an existing server into
a smaller server with only the specified modules (and their transitive
dependencies).
The way this will work in practice is that each Wildfly sub project will
produce two different server artifacts, one of which is a server without
any jars using artifact references, and a more traditional version with
jars packaged in the module directory. Downstream projects will consume
the smaller version without all the jars, so when a version changes the
download should be less than 5mb rather than larger than 100mb (the
plugin has the ability to turn a server that uses artifact references
into a server that contains the jars in the modules dir).
Basically the upshot is that it should be basically possible to build
whatever configuration of server you want once this is part of our build
process, and we should also be publishing lightweight server artifacts
that use the jars in the maven repo as well as our traditional
'everything and the kitchen sink' build.
It is anticipated that 3rd party projects build on Wildfly would also
use this plugin (I think at the moment the standard approach has been to
copy and modify our ant scripts).
This is still very much a work in progress, so nothing is set in stone
yet and any comments are welcome.
