In case you don't have a plugin to create and attach main artifact for you, there is a more generic solution with Groovy Maven plugin:

    org.codehaus.gmaven
    groovy-maven-plugin
    2.1
    
        
            set-main-artifact
            package
            
                execute
            
            
                
                    project.artifact.setFile(new File(project.build.directory, project.build.finalName + ".zip"))
