-     <answer>
-       <p>There is a problem in some versions of Maven (earlier than 3.0-alpha-1) that prevent Maven from correctly resolving
-          plugin dependencies in a multi-module build (MNG-1323).  This means that if you have multiple
-          modules in your project and the antrun plugin declares a different set of dependencies, only the first
-          declaration found will be used.</p>
-       <p>The workaround for this is to specify the same set of plugin dependencies for all declarations of the
-          antrun plugin.  Another option is to move the plugin dependencies to the project level and set the
-          scope to "provided".  For more information, see MANTRUN-51 and MANTRUN-106.</p>
