Has anyone had problems with scala code-completion in IDEA when using sbt?

Question

I recently switched to sbt (which I completely dig) and as soon as I started to compile and run tests from sbt, code completion in IDEA seems to come and go... very strange.

Answer 1

I've seen similar behavior in Netbeans IDE, when one of the libraries (Lift in particular) was depending on Scala 2.7.7 (not Scala 2.8). When scala-lang library 2.7.7 was on a class-path, that was somehow breaking the Scala support in Netbeans at all.

So check your PATH system variable, and the classpath.
