maven-plugin-plugin failing in reactor

[Nigel Magnay]

I have a mojo building with groovy. In my pom I have

    <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-plugin-plugin</artifactId>
                <version>2.3</version>
                <dependencies>
                    <dependency>
                        <groupId>org.codehaus.mojo.groovy</groupId>
                        <artifactId>groovy-mojo-tools</artifactId>
                        <version>1.0-beta-2</version>
                    </dependency>
                </dependencies>
                <configuration>
                    <extractors>
                        <extractor>groovy</extractor>
                    </extractors>

                </configuration>
            </plugin>


This all works fine when the plugin is compiled in isolation. However, when
compiled as a module from the parent, it fails with

INFO]
------------------------------------------------------------------------
[INFO] Error extracting plugin descriptor: 'No extractor for language:
groovy'
[INFO]
------------------------------------------------------------------------

Anyone seen this or is it just something for JIRA ?
