Replace maven with a shell script

One of the things I find myself trying to instill in a lot of our developers these days is that a little pragmatism can often go a long way.

By popular demand (really!), here’s my trivial shell script that pretends to be maven. For smallish projects and small sizes of your local maven repository, it is orders of magnitude faster than doing an actual maving run, and it has many other advantages over the “real” maven.

Of course, I don’t actually use this script (much). Lately I’ve been using Ant 1.7 with Ivy. Oh, And mod_perl‘s Apache::Test for TripleSoup.
