Setting up Java development environment

I had too much grief with STS, it stomped all over my repositories (filling them up with maven shit like configs and local sources, everything took hours to do (what with maven pulling down and refreshing stuff all the time), then STS started crashing, went back to Eclipse which was a bit better, but not much. In the end I just jumped to Intellij for Java stuff, works like a charm.
