[gatein-dev] Build update

[Matt Wringe]

I think the real issue is that we are preforming releases on our own
developer machines. This is not a very reproducible or auditable process
(ie developer can specify profiles or options during the build, local
maven repo may have some dirty jars, sources may not not be exactly what
has been committed, ...). 

Having a release system in place would solve a lot of these issue. We
should really use something like hudson, and all that we need to do to
release product or a component is to click a button and let the system
take care of the rest. This would ensure that the maven repo is properly
configured, that the correct profiles are specified, that the release
version is properly specified, etc..

Of course it is always possible to have it working by selecting the good profiles in the release plugin and on the command line, however it is error prone and it is hard to figure out by looking at the build what should be used.

Obviously we need to address developer productivity and we do provide a way to perform a build that saves the most time we can when it is activated in a simple manner.
