Add a build step to a Play 2.0 (scala/sbt) project

Question

I'm writing a Play 2.0 project in Scala, and I need to run a command-line tool before SBT starts deciding what to compile (the command will create/replace a .scala file in the project with one generated from some data). I'm a complete novice in SBT, and some quick time on Google didn't turn up anything promising. How should I do this?

Answer 1

For creating sources prior to compilation, have a look at source generators:
