Scala & Maven – POM Example

Today, there is no waffle about what Scala or Maven is. This is just the plain configuration to build Scala projects with Maven. If you want more detailed information check Maven for Beginners at scala-lang.org or browse through the documentation of the Scala-Maven-Plugin.

By the way,the configuration works as well if you want to mix Java and Scala within a single project. Just place your scala files in src/main/scala and your Java files in src/main/java (or the src/test equivalents). Maven will do the rest for you.

Enjoy!
