Hi,

Based on a brief discussion with Angela, here's the current build

(Yeah, I use a desktop.)

Here's the result with tests disabled (mvn clean install
-Dmaven.test.skip=true):

Test times are dominated by core, spi2jcr and ocm, and build times by
standalone.

One way we could make the builds faster (IMHO it should always be
faster to build the project than to fix even a simple bug...) for
typical development is to define a set of profiles like "with-spi",
"with-ocm" and "with-standalone" that would be on by default, but that
you could disable in your local Maven settings if you're not working
on those components. We still have the Hudson build to flag any global
build failures.

The formation of the JCR Commons subproject should help the build
times somewhat. I'll also try to look at ways to speed up the
standalone build. It's mostly dependent on moving lots of bits around,
but perhaps there are some extra copies that we could avoid.

BR,
