Axel,
Sorry, but it’s not possible for us to generate Ant scripts for our packaging. We used to use Ant in earlier versions of ME, but since Ant can’t follow Eclipse links properly we had to abandon it in order to enable greater project flexibility that our users were demanding.
When actually packaging applications to go to QA or production, we recommend that you pull them directly from your source repository, recompile and then package them using Ant or the build tool of your choice.
