Maven not executing my Ant target

I'm trying to do something really simple: run an Ant task from Maven. Foolproof, right? Wrong.

Here's my pom:

What am I doing wrong? When I run mvn install, the Ant target never gets executed. Is there a better way to do this? I simply need to copy certain files in my resources directory and the main swf to a local directory so I can test it on my localhost HTTP server.

If you look at the usage site of the maven-antrun-plugin you will see that also a goal is specified in the plugin configuration

        <goals>
          <goal>run</goal>
        </goals>

I suppose you have to add this.
