Hi there !

I just start playing around with maven2-beta-3. As suggested by the docu i created a sample project with

>m2 archetype:create -DgroupId=com.mycompany.app -DartifactId=my-app

acording to
http://maven.apache.org/maven2/plugins/maven-antrun-plugin/usage.html

i edited the pom.xml, so it now looks like:

<project xmlns="http://maven.apache.org/POM/4.0.0"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd";>

         <configuration>

             <echo message="ANT TASK"/>
           </tasks>
         </configuration>
         <goals>
           <goal>run</goal>
         </goals>
        </execution>
       </executions>
     </plugin>
   </plugins>
  </build>

</project>

when i call "m2 install", i get the following stack-trace:


C:\src\mavenTestProject\my-app>m2 install

What am i doing wrong ? Any hints are welcome.
btw, commenting out the line <goal>run</goal> fixes the issue, but the ant-task is not called.

Greeting and thanks,
