Short code for Antrun Maven plugin

<build>
  <plugins>
    <plugin> <artifactId>maven-antrun-plugin</artifactId>
      <executions> <execution> <phase>initialize</phase>  <goals><goal>run</goal></goals> <configuration> <tasks>
        <echo>  *** Hello from Ant! ***  </echo>
      </tasks> </configuration> </execution> </executions>
    </plugin>
  </plugins>
</build>

To use Ant tasks not included in the Ant jar, like Ant optional or custom tasks, you need to add the dependencies needed for the task to run to the plugin classpath and use the maven.plugin.clas­spath reference if needed.
