  * This mojo looks at the dependencies after final resolution and looks for mismatches in your dependencyManagement

- * dependencyManagement. See <a href="https://issues.apache.org/jira/browse/MNG-1577">MNG-1577</a> for more info. This
- * mojo is also useful for just detecting projects that override the dependencyManagement directly. Set ignoreDirect to
