That has not been my experience at all. SBT has always worked correctly for me.
When was the last time you used Scala and/or SBT? I know a lot of the tools in the Scala ecosystem were unstable prior to Scala 2.8. However, now they have become pretty good. Even the, previously notoriously bad, Eclipse plugin has become good.
~6 months ago. I'd certainly say the eclipse plugin has improved a lot, it's better than the intellij one now. It is still quite a ways away from good though.
