Sharing src/test classes between modules in a multi-module maven project

Question

I have a multi-module Maven project. For the sake of this example, consider two modules:

• data
• consumer

Modul

Answer 1

Your Consumer project depends upon your Data project, therefore we are happy that Data must be built prior to Consumer. As a result, using the techniques suggested in the comments, I would ensure your Data project contains all the test code that you wish to share and configure the POM to produce a test JAR:

  org.apache.maven.plugins
  maven-jar-plugin
  2.2
  
    
      
        test-jar
      
    
  

Your Consumer project would then depend upon both the normal Data JAR artifact, plus the additional test-jar artifact, with test scope of course:

  com.foo
  data
  1.0
  test-jar
  test

I've used this approach on many occasions and it works well.
