Why wlappc ANT task forces aways the generation of the EJB classes ?

Question

I've got a problem with the ANT task "wlappc" witch interfaces Weblogic compilator.
In fact, I would like to execute the ebj compilation only when needed (if the deployment descriptor or a class changed for example).
It seems that this is the default behavior and the 'forcegeneration' option of the wlappc Ant task can change it (the doc is below).
forceGeneration :
Forces generation of EJB and JSP classes. Without this flag, the classes will not be regenerated unless a checksum indicates that it is necessary.
So I wrote :
<wlappc source="${descriptors}/CommandeEntities" output="${build}/CommandsEntities.jar" keepgenerated="true" verbose="true" forcegeneration="false">
     <classpath refid="ejb.classpath"/>
</wlappc>
but I got the folowing result :
ejbjar:

BUILD SUCCESSFUL
All the classes witch hasn't changed has been checked and regenerated. The compliler says "Recompiling because no previous hashes found".
But why ? It could be besause it creates a different working directory each time I execute this ant task ? Is this working directory configurable ?
Would you have any idea of what's happening ?
Thanks.

You can find this in the 'org\apache\tools\ant\taskdefs\defaults.properties'
file of %wl-home%\server\lib\ant\ant.jar

I mean the definition of "wlappc" not the help for wlappc???thx.
i.e.
where can i find the sentence list below:
<taskdef name="wlappc" classname="weblogic.ant.taskdefs.j2ee.Appc"/>
I mean which files this "taskdef" is being in .
