Maven: share sources between projects

I have two projects which are child of a common parent project. There is also a generator project and a corresponding maven plugin project for the generator. Also, both child projects are using the same input file, which is used for the code generation:

parent: pom
  child1: jar
    src/main/generator/input.gen
  child2: jar
    src/main/generator/input.gen
  generator: jar
  generator-plugin: maven-plugin

The generator plugin is an in-house made Maven plugin:

@Mojo(name = "generate", defaultPhase = LifecyclePhase.GENERATE_SOURCES, threadSafe = true)
public class GeneratorPlugin extends AbstractMojo {
    @Parameter(required = true, readonly = true, defaultValue = "${project}")
    private MavenProject project;
    @Parameter(required = true, defaultValue = "${project.basedir}/src/main/generator/input.gen")
    private File         input;

   ...

}

Currenlty, this input.gen is duplicated in src/main/generator/input.gen of both child1 and child2. This is a problem. I would like to have just one version of input.gen.

How should I structure my projects and how should I refer to this shared copy in <configuration><input>...</input></configuration> for the generator-plugin plugin in the pom of the two child projects?

My take would be (not tested):

  • Put input.gen into a shared dependency in src/main/resources
  • Modify the generator to accept classpath resources as input instead / in addition to files
  • Add the shared dependency with input.gen as provided scope to prevent it from ending up in the final product

The Maven Remote Resources Plugin might be what you're looking for.

Here is an example.
