I have an sbt project which I ran "gen-idea" to setup to work with Intellij 12.4. In one project is my main code an the other project has my macro code. When trying debug my macro via a test file by following http://docs.scala-lang.org/overviews/macros/overview.html but throws:
error: scala.reflect.internal.MissingRequirementError: object scala.runtime in compiler mirror not found.

I have checked to ensure that in my class path that ALL jars from SCALA_HOME/lib/ are included and they are. Btw this is with Scala v2.10.2
As we figured out at #scala, the documentation was missing the fact that one needs to provide the -Dscala.usejavacp=true argument to the JVM command that invokes scalac. After that everything worked fine, and I updated the docs: http://docs.scala-lang.org/overviews/macros/overview.html#debugging_macros.
