How to compile mixed (Java and Groovy) project?

Question

I have a project (Java Swing application), in which I want to mix Java and Groovy.

I can compile and run the project without problems inside IntelliJ Idea.

But I can't compile it with Maven:

1. In src/main/groovy I define a Groovy class GroovyClass .
2. In src/main/java there is a Java class, which uses GroovyClass .
3. When compiling the project with Maven, I get the message [ERROR] ...\\JavaClass.java:[13,47] error: cannot find symbol .

How can I change the pom.xml file in order to be able to compile and package the application using Maven?

Add the groovy-eclipse compiler maven plugin to your pom.xml

Instructions are on the plugins page at https://github.com/groovy/groovy-eclipse/wiki/Groovy-Eclipse-Maven-plugin
