as I wrote earlier I had a problem with the anttask not finding my classes (since separation
of classes/mappinfiles). I'm now using the java task to run the main method of SchemaExport.
To make things easier I added a switch to the commandline where one can specify the
directory which holds the mappingfiles. The switch loads all mappingfiles (ending with .hbm.xml)
to the hibernateconfiguration.
The ant target for creating the ddl would look like:
</target name="createdatabase">
<java classname="net.sf.hibernate.tool.hbm2ddl.SchemaExport" fork="yes">
<arg value="--mappingdir=dir/to/mappingfiles/"/>
<arg value="--quiet"/>
<arg value="--properties=build/hibernate.properties"/>
<classpath refid="classpath"/>
</java>
</target>
Later I might change the ant-task schemaexport as well to have a classpath (which looks like the cleaner solution).
Maybe somebody finds that interesting and will apply that to the hibernate source. This is a patch against
the latest hibernate source from today (a.k.a 2.0.2).
