Help with Multi Module JavaDocs

[Andrew Hughes <ah...@gmail.com>]

Hi All,

I am having trouble with javadoc's on my multi module projects. Creation of
the javadoc's takes forever... when I run 'clean install site' I see the
following 'javadoc has not be previously called' log's for every module...

[INFO] ------------------------------------------------------------------------
[INFO] Building module-d

....truncated other reports output...
[INFO] Generating "JavaDocs" report.
[WARNING] Source files encoding has not been set, using platform
encoding Cp1252, i.e. build is platform dependent!

If I have 6 modules [a..f] as above, then javadoc is run 6x6=36 times
in total. Build times are oh so slow when building the site...

My parent pom config with maven 2.2.1 and javadoc v2.5 is as follows...

<reporting>
    <plugins>
        <plugin>
            <artifactId>maven-javadoc-plugin</artifactId>
            <configuration>
                <source>${maven.compiler.source}</source>
                <maxmemory>512m</maxmemory>
					<useStandardDocletOptions>true</useStandardDocletOptions>
                <doclet>gr.spinellis.umlgraph.doclet.UmlGraphDoc</doclet>
                <docletArtifact>
                    <groupId>gr.spinellis</groupId>
						<artifactId>UmlGraph</artifactId>
                    <version>4.6</version>
                 </docletArtifact>
             </configuration>
        </plugin>
    </plugins>
</reporting>


Any idea what I am doing wrong here?

CHEERS :)
