I just got started with Scala/LiftWeb/Sbt developing, and I\'d like to import a Sbt project in IntelliJ Idea. Actually, I managed to import my project in two different ways:
I just went through all this pain. I spend days trying to get an acceptable environment up and have come to the conclusion that ENSIME, SBT and JRebel are going to be my development environment for some time. Yes, it is going back to Emacs, but ENSIME turns it into a bit or an idea with refactoring, debugging support, navigation, etc. It's not nowhere near as good as Eclipse (Java), but unless the scala plugins work better it's the best we have.
Until the Scala development environments get up to snuff (Eclipse or IntelliJ) I'm not going to bother. They're just way too buggy.
See the discussion on the lift site.

Within that thread, there is a link to a HOWTO for IntelliJ, but although it kinda works, there are many issues that render it a little less that useful.
