How can the checkstyle plugin be configured to fail the build?

[Andrew Moores]

Hello

I want to make my build fail if there are any checkstyle errors in my code.  I 
have added the following to my pom:

<build>
  <plugins>
    <plugin>
      <groupId>org.apache.maven.plugins</groupId>
      <artifactId>maven-checkstyle-plugin</artifactId>
      <configuration>
          <failOnViolation>true</failOnViolation>
      </configuration>
    </plugin>
  </plugins>
</build>

When I execute mvn checkstyle:check my build fails when I have a checkstyle 
error.

When I execute mvn install the build does not fail.  Reading the plugin pages I 
expected my build to fail for the intall goal as well, what else do I need to 
add to the POM to make the build fail?

I am running Maven 2.0.5.

Thanks
Andrew
