[m2] maven-jdepend-plugin:FATAL error, NullPointerException

Hi,

I want to use the plugin for jdepend in maven 2.

With google I found

http://mojo.codehaus.org/jdepend-maven-plugin/howto.html
http://www.ibiblio.org/pub/packages/maven2/maven/maven-jdepend-plugin/1.5/

I added ibiblio to my pom

   <pluginRepositories>
     <pluginRepository>
       <id>ibibliorepo</id>
       <name>ibiblio repo</name>
       <url>http://www.ibiblio.org/pub/packages/maven2</url>
  	  <layout>legacy</layout>
     </pluginRepository>
   </pluginRepositories>

and added the plugin to the pom

   <reporting>
       <plugin>
         <groupId>maven</groupId>
         <artifactId>maven-jdepend-plugin</artifactId>
         <version>1.5</version>
         <configuration>
         </configuration>
       </plugin>
     </plugins>
   </reporting>

It downloaded the jar and pom:
