 -----------------------------
 Even though this plugin tries to be compatible with every Maven version there are some known limitations with specific versions. Here is a list that tries to outline the current state of the art:
 
-| Maven Version               | Plugin Version  | Notes                              |

 Starting with Maven 3.1.1 any plugin version is currently compatible. Only known exception is for Maven 3.3.1 and Maven 3.3.3 where the plugin version 2.1.14 is not working properly.
