I don't find the answer in the doc nor in the source code of PCEnhancerTask.
Basically, I'm not able to choose the persistence unit from ant task for the build-time enhancer.

The "-p #[pu_name]" stuff is from the command line, not from ant.

Exploring the source code of PCEnhancerTask doesn't helped me.
I'm not sure but it might confirmed it is just not possible :

    protected ConfigurationImpl newConfiguration() {
        return new OpenJPAConfigurationImpl();

No persistence unit as a parameter ?
On the other hand, this method doesn't appears to be called :
What is that getConfiguration() method ?
Can't find it in the class, so it must be from superclass witch is from Ant, so no possibility
to pass the persistence unit ?

    protected void executeOn(String[] files)
        throws IOException { = (dirName == null) ? null
            : Files.getFile(dirName, getClassLoader());
        OpenJPAConfiguration conf = (OpenJPAConfiguration) getConfiguration();
        MetaDataRepository repos = conf.newMetaDataRepositoryInstance();, files, flags, repos, null, getClassLoader ());

Any idea ? I'm totally in the dark ...
