project from another, maven requires a minimum set of elements to be specified
  in each project's pom.xml.

   - [modelVersion] tells maven which version of the object model this project
       is compliant with (to support future legacy concerns)

   - [artifactId] tells maven what the artifact name is for this particular
       project. Each project should have a distinct artifactId.
