     | Specifies a repository mirror site to use instead of a given repository. The repository that
     | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
     | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.

 * <li>Download and Cache: If Maven finds the artifact in a remote repository, it downloads it and stores it in the local repository for future use.</li>
 * </ol>
 * <p>By caching artifacts in the local repository, Maven minimizes the need to repeatedly download the same artifacts, thus optimizing the build process.</p>
