We've recently implemented a Maven builder for Anthill Pro -- it's not released yet but will be part of version 2.1. We will probably implement a Maven builder for Anthill OS sometime soon as well. In the meantime, check out how some people have gotten Maven builds to work with Anthill in the past -- http://lists.urbancode.com/pipermail/anthill/2002-December/000543.html
Cool! Thanks Maciej!
