Lars, one solution is to use the exec task and call the zip system file (I
work on OS X and Linux, your mileage may vary)
<target name="epub-zip">
<!-- We use exec zip because I can't figure out if the builtin zip task
conforms to what ePub expects -->
<!-- Zip the mimetype first without compression as required-->
<exec executable="zip">
<arg line="-X0 ${src_file}.epub mimetype"/>
</exec>
<!-- Then zip the other files into the zip/epub archive -->
<exec executable="zip">
<arg line="-r -X9 ${src_file}.epub META-INF OEBPS"/>
</exec>
</target>
Hope this helps
