       project. Each project should have a distinct artifactId.

   - [version] tells maven what release of this artifact we're trying to produce.
       The fact that a project has a distinct pom.xml should indicate a separate
       release cycle that is also distinct to that project, so a concrete version
       declaration is required.

   - [name] tells maven what the user-friendly name of this project is. The name
