What exactly is this target supposed to accomplish?  When would classes be compiled by eclipse and not picked up by the compileaction/compilemodel targets?

<target name="copyclasses" depends="init,groovy.copyactions" description="Copy the classes that were compiled by eclipse">
        <!-- TODO check how the groovy eclipse plugin works, does it compile? -->
        <copy todir="${classes.model.dir}">
            <fileset dir="classes/main">
                <include name="**/*.class" />
            </fileset>
        </copy>
        <copy todir="${classes.action.dir}">
            <fileset dir="classes/hot">
                <include name="**/*.class" />
            </fileset>
        </copy>
    </target>
