Playing around with maven, scala and java I’ve found it useful to have both, java and scala, in one project. After searching for a while I’ve found several sources which helped me solving this point.
Everything which is needed is a standard quickstart project of maven. The folder structure has to be extended by the both directories:
After that you’ve got to add the following lines to the pom.xml of the maven project:
To use scala in the project you’ve got to add an additional repository:
... <repository> <id>scala-tools.org</id> <name>Scala-tools Maven2 Repository</name> <url>http://scala-tools.org/repo-releases</url> </repository> <repository> <id>scala-tools.org</id> <name>Scala-tools Maven2 Repository</name> <url>http://scala-tools.org/repo-releases</url> </repository> ...
Within the dependency-section you’ll need to add the needed library:
After that I had to add the maven-scala-plugin to the build-lifecycle.
After that it was possible to use scala and java in one project (of course in diffrent directories).
Some other people put the maven-compiler-plugin below the maven-scala-plugin to define the order of execution.
If there are any Eclipse-Users outside: There is a m2e-scala connector which connects the lifecycle of the maven-scala-plugin to m2e. This makes the development on Eclipse much easier.
