[M2] Managing Project License

[Rémy Sanlaville]

I am trying to manage the project license in our development.

1) I would like to add a report in order to indicate in which files the
license header is missing.
I tried with maven-checkstyle-plugin (cf.
http://maven.apache.org/plugins/maven-checkstyle-plugin/tips.html)
but It did not worked. The build success but the checkstyle report is
empty...

 <reporting>
   <plugins>
     <plugin>
       <groupId>org.apache.maven.plugins</groupId>
       <artifactId>maven-checkstyle-plugin</artifactId>
       <version>2.2-SNAPSHOT</version>
       <configuration>

<configLocation>${basedir}/src/main/config/checkstyle.xml</configLocation>

<headerLocation>${basedir}/src/main/config/LICENSE.txt</headerLocation>
       </configuration>
     </plugin>
   </plugins>
 </reporting>


2) I wonder if it possible to automatically add the license header if it
missing in a file.
