Odd, it seems to work for me. This is a brand new machine since my old was bricked, so I don't have any leftover caches or anything. Did you muck with the project/build.sbt file to change the version or add more plugins?

During the initial build, there was an "out of memory" problem. My machine has only 4 GB. I'll give it another go and report back here. Thanks for responding.

[tomjridge]

I've increased memory to 6GB. I still get a "java.lang.OutOfMemoryError: PermGen space" when compiling, but compiling again succeeds and the application now runs. Thanks for your help.

[lihaoyi]

Did you give your jvm more memory? Just because your machine has 4gb doesn't mean it'll use it. I think it defaults to 256mb or 512mb or some relatively small quantity like that
