 * When {@code --plugins} option is enabled (or by default), upgrades plugins known to fail with Maven 4:
 * <ul>
 *   <li><strong>maven-exec-plugin</strong>: Upgrades to version 3.2.0 or higher</li>
 *   <li><strong>maven-enforcer-plugin</strong>: Upgrades to version 3.0.0 or higher</li>
 *   <li><strong>flatten-maven-plugin</strong>: Upgrades to version 1.2.7 or higher</li>

  maven occur, the maven inheritance model must be pinned against a particular
  modelVersion. This is required so that a change from modelVersion 4.0.0 to
  4.1.0 doesn't cause compatibility problems with users who have not upgraded
  their projects. It also allows for a certain amount of legacy support into the
  future. Therefore, we should rename this file from pom.xml in the maven-core
