When I started programming in Scala I was naturally looking for a suitable IDE. Due to former experience and preference, I disregarded Eclipse and tried Netbeans with its Scala plugin but could not get it running properly. I had more luck with IntelliJ IDEA, that is it worked. But it is performing sluggishly and has a lot of bugs. In particular, many compiler errors are not found by IDEA, and some things it marks as errors are none. Scala’s complex type system is not all well implemented, so syntax completion is no help, either. That the Scala compiler itself runs at turtle speed was merely the last drop in my barrel of discomfort. As it was, working productively was impossible. Therefore, I decided to switch to a regular editor and simple-build-tool, something I saw mentioned everywhere people asked for good Scala IDEs.
