This is the idea that I had implemented in CJAN as an Ant Task. You defined
${local.repo} and ${remote.repo} and then did a get of say velocity (the
latest was the default to get, or you could specify a version), check it
out and steal it for jjar. This is exactly what I was wanting to do, and I
believe the example I have in the cjan directory does what you are talking
about. You just need to plug in jjar as the backend, I think.
