* <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>
