Signing jars before deployment

[Yo...@gd-ais.com]

Does anyone know of a good way to sign jars before deploying them?  I've
tried writing the following goal:

        <goal name="jar:sign">
                <attainGoal name="jar:jar"/>
                <signjar jar="${maven.build.dir}/${maven.final.name}.jar"
alias="milkshake" storepass="frylock"/>
                <attainGoal name="jar:deploy"/>
        </goal>

Unfortunately, after the jar is signed the deploy goal causes the jar to be
built again, without being signed.  I couldn't seem to find any properties
in the jar plugin reference to help with this, so I was wondering if anyone
has any idea what the best approach to this would be.  Thanks.
