Maven Groovy and Java + Lombok

I am trying to add groovy to an existing Java Maven project that leverages Lombok. Unfortunately when I enable the groovy-maven-eclipse compiler with the pom fragment below, my lombok annotated java files fail to compile. As far as I can tell, Lombok is not participating in the compilation of java files at all.

<plugin>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>2.3.1</version>
    <configuration>
        <compilerId>groovy-eclipse-compiler</compilerId>
        <verbose>true</verbose>
    </configuration>
    <dependencies>
        <dependency>
            <groupId>org.codehaus.groovy</groupId>
            <artifactId>groovy-eclipse-compiler</artifactId>
            <version>2.6.0-01-SNAPSHOT</version>
        </dependency>
    </dependencies>
</plugin>

I should also point out that while in eclipse (with m2e) everything works fine. My problem arises when I try to do a mvn package.
