The Java IDE download of Eclipse - it's just the base IDE with all the Java addons. The editor is fantastic, I hate the rest of the design paradigm but I also hate IntelliJ's - it never clicked with me.

The quality of all the other addons are variable from amazing to trash (because there is a commercial version they'd rather you bought).

That was always the problem with Eclipse foundation - the struggle between what's free in the IDE and what's commercial and how to drive spenders towards the commercial solutions.
