            Maven looks for the parent pom first in the reactor of currently building projects, then in this location on
            the filesystem, then the local repository, and lastly in the remote repo.
            &lt;code&gt;relativePath&lt;/code&gt; allows you to select a different location,
            for example when your structure is flat, or deeper without an intermediate parent pom.
            However, the group ID, artifact ID and version are still required,
            and must match the file in the location given or it will revert to the repository for the POM.
            This feature is only for enhancing the development in a local checkout of that project.
