Hi Jon.

As fas as I understand your problem description, the filtering mechanism of the
copy task should help you. Just define tokens to be filtered like this:
<filter token="Version" value="${build.vers}"/>
and copy your source template file into your source tree before compiling with:
<copy tofile="" filtering="on" file=""/>

Have you been looking for this?
