An example SBT project which uses macros (Scala 2.10, SBT 0.13)
To verify that everything works fine, do sbt run.
Note that currently SBT doesn't support recompilation of macro clients if the dependencies of the macro implementation have changed - macro clients are only recompiled when the macro definition itself is: sbt/sbt#399.
Huge thanks to Paul Butcher (https://github.com/paulbutcher/ScalaMock/blob/typemacros/project/Build.scala) and Adam Warski (https://github.com/adamw/scala-macro-debug) whose SBT projects I used as prototypes for this one.
