grouper-ws build script does not copy grouper/lib/custom

Hello,
I notice an error when doing some tests with Grouper's WebService. This was in Tomcat's catalina.out when Grouper is starting when I accessed the WebService status page :

Grouper error: Cant process property hooks.group.class in resource: grouper.properties, the current value is 'ca.umontreal.dgtic.grouper.hooks.GroupUniqueExtensionHook', which should be of type: edu.internet2.middleware.grouper.hooks.GroupHooks, java.lang.RuntimeException: Problem loading class: ca.umontreal.dgtic.grouper.hooks.GroupUniqueExtensionHook

We added a Group Hook in the Grouper API in Grouper's .../api/lib/custom (groupUniqueExtension.jar) and included it in grouper.properties :
hooks.group.class=ca.umontreal.dgtic.grouper.hooks.GroupUniqueExtensionHook

After rebuilding the web service (using ant dist or ant quick) I did a search in the web service's dist folder and the groupUniqueExtension.jar file wasn't found. I figured this was the problem since the WS tried to load a class that doesn't exist. I tried to copy it in the WebService's lib folder (WebService/build/dist/grouper-ws/WEB-INF/lib/) and the exception is gone.

Building the UI doesn't have that problem, since the whole lib/custom folder (containing the Hook jar file) is copied and the hook is working properly.

My question :
Should the jar be copied automatically in the WS's lib folder ? As far as a I know the whole lib/custom folder isn't copied in the web service.
or
Should I copy it manually ? It doesn't sound practical but my test showed that it worked
or
Should I edit grouper.property to remove the hook in the WebServices ? I don't think so since we wouldn't want WS transaction to create groups with the same extension.

Thank you all
