Using the hivedoc-plugin

To get all your hivemodule.xml's documented just include the following snippet in you pom (assuming a working Maven 2 installation and access to the central repository):

<reporting>
        <plugins>
                 ...
                <plugin>
                        <groupId>ch.marcus-schulte.maven</groupId>
                            <artifactId>hivedoc-plugin</artifactId>
                            <version>1.0.2</version>
                </plugin>
        </plugins>
</reporting>

Make sure to also enable the maven-javadoc-plugin to benefit from automatic links to the javadoc.

If, for some reason, you cannot use the central repository you can download a repo-bundle (including sources) here
