"...the use of Ant and Maven as project files..."

This is what I want most from a Java IDE. I find IDEs project configuration complex, arbitrary, inscrutable, and un-diffable (making version control on the project files mostly useless).

Eclipse and IntelliJ make some effort to work with Maven and Ant, but tend to get out of sync in hard to debug ways.

Android Studio (Google's fork of IDEA) was awful at the beginning but is on the right track to getting quite good with Gradle.
