[rules-dev] building Drools non-networked

When building Drools, Maven seems to pull a lot of stuff in from the networked repos when I build Drools. Even a "mvn clean" pulls down info from the net. Is there an easy way to build in a non-networked environment? I.e. can you preload the dependencies, or build without Maven? I'm not looking to rewrite the build process; I'm just wondering if it's possible without substantial work. reid
