How can I make the test jar include dependencies in Maven?

Question

I have a project with src/main/java and src/test/java structure, and I managed to use maven-jar-plugin to build a jar of the test branch. However, I want to package the test

I had a similar problem with integration tests I need to run on Hadoop. Our integration tests are located in the test folder of a separate integration test module, so what is required is a test-jar-with-dependencies to make our life easier.

I'm using the assembly plugin as mentioned by Michael-O. My assembly descriptor is located in src/main/assembly/test-jar-with-dependencies.xml and is a modification of the standard jar-with-dependencies descriptor that's part of the plugin:

    test-jar-with-dependencies
    
        jar
    
    false
    
        
            /
            true
            
            true
            true
            test
        
    

This assembly relies on the test-jar being created as part of the module build. So I added the following to the module's pom.xml:

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


    org.apache.maven.plugins
    maven-assembly-plugin
    
        
            src/main/assembly/test-jar-with-dependencies.xml
        
    
    
        
            package
            
                single
