create eclipse groovy-java project with maven

Question

I have a Java-Groovy Eclipse project that I build with Maven. I have added the Maven Groovy plugin to the pom.xml such that I can build/test the Java and Groovy sources on the command-line using Maven.

I would like to have some way to automatically generate the Eclipse .project and .classpath files from my pom.xml. If I run mvn eclipse:eclipse it seems to assume that it's a Java project, so there's no way to (for example) run the tests in src/main/groovy from within Eclipse.

I'm using the STS Eclipse distribution, which includes support for Groovy/Grails. All I'm missing is a way to automatically create the appropriate .classpath and .project files.

Thanks!

P.S. I know IntelliJ is better, but I don't have a license

Here is configuration I found that works when Java calls Groovy code and when Groovy calls Java code fitting good within groovy eclipse IDE plugin (nature).

There is no need for additional source folders for groovy. It just works!

Using:

mvn clean install eclipse:clean eclipse:eclipse
