Learning Groovy and Scala I did some spikes and katas with Maven. If you want to quickstart a project either with Groovy or with Scala, you may find my quickstart projects useful.
Scala
For Scala 2.8.1, JUnit 4.8.2, Hamcrest 1.2 and ScalaTest 1.2, clone this Git repository:

Groovy
For Groovy 1.7.6 and JUnit 4.8.2:

Happy coding!
