The project is delta.
I've already installed sbt-1.2.8 on my Mac. However, I can't compile this project by using "build/sbt compile". After I type the command and the error is below:

Error during sbt execution: java.lang.NoClassDefFoundError: scala/reflect/internal/Trees
I'm a newbie to sbt tools. I've tried to change the sbt version in project/build.properties, but it didn't work. Anyone can help me figure this out?
