I ran into this last week, and found a fix for it. I'll try to update
the guide to use a more recent version of maven-plugin-plugin.
For the time being here's a snippet from my POM:
...
<prerequisites>
<maven>2.0.10</maven>
</prerequisites>
<build>
<pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-plugin-plugin</artifactId>
<version>2.5</version>
</plugin>
</plugins>
</pluginManagement>
<plugins>
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-plugin-plugin</artifactId>
<!-- Add the Ant plugin tools -->
<dependencies>
<dependency>
<groupId>org.apache.maven.plugin-tools</groupId>
<artifactId>maven-plugin-tools-ant</artifactId>
<version>2.5</version>
</dependency>
</dependencies>
</plugin>
</plugins>
</build>
<dependencies>
<dependency>
<groupId>org.apache.maven</groupId>
<artifactId>maven-script-ant</artifactId>
<version>2.0.10</version>
</dependency>
</dependencies>
