I wonder where I can get an RC1 build of the contrib jar. If it's a jar file, I wonder why you're supposed to build it yourself using mvn.
Edit: Don't have to build it. It's included in the zip file on the download page. The new clojure-contrib-1-2.0.jar is just significantly smaller than the version 1.1 and older.
Edit2: It appears you can indeed build on Windows if you skip the maven tests: mvn package -Dmaven.test.skip=true
Whether skipping maven tests is a good/bad thing I don't know.
