I'm on a project where we use NetBeans (6.8). We use several different web services, which we have added as web service references, and Netbeans auto-generates the Ant wsimport scripts for us. Very handy, with one drawback: The web service clients are recompiled every time ant is invoked. This slows down the build process considerably and has caused the number of sword-related injuries, maimings and deaths to skyrocket.

Normally, I'd fix this by changing the wsimport element from

<wsimport 
    sourcedestdir="${build.generated.dir}/jax-wsCache/PonyService"
    destdir="${build.generated.dir}/jax-wsCache/PonyService"
    wsdl="${wsdl-PonyService}" 
    catalog="catalog.xml" 
    verbose="true"/>

to

<wsimport 
    sourcedestdir="${build.generated.dir}/jax-wsCache/PonyService"
    destdir="${build.generated.dir}/jax-wsCache/PonyService"
    wsdl="${wsdl-PonyService}" 
    catalog="catalog.xml" 
    verbose="true">
    <produces dir="${build.generated.dir}/jax-wsCache/PonyService" />
</wsimport>

But I can't, 'cause this part of the Ant script is auto-generated. If I right-click the PonyService web service reference and select Edit Web Service Attributes ⇒ wsimport options, I can add attributes to the wsimport element, but not child elements.

So: How do I add the produces child element to wsimport other than hacking the auto-generated Ant script?

Or more generally: How do I make the NetBeans-generated wsimport not recompile the web service clients every time I build?
