Just add a <resource> definition to your index for the hbm2ddl jar, then 
  you can use a property to access the repository location.

     <x:property name="filepath" key="hbm2ddl" feature="path"/>

The property "filepath" now contains the location of the hbm2ddl jar 
file and you can use this to construct a <classpath> - for example:

       <classpath>
         <pathelement path="${magic.cache}/${filepath}"/>
       </classpath>

You can also use <x:path> but I need to get the docs in place on that 
first of all.  Basically you can use <x:path> to get a dependency chain 
as a proper ant path object that you can reference using refid.  The 
following example get the build time path for the current project:

     <x:path id="build.path" mode="BUILD"/>
