Hmmm ... wouldn't it be nicer to start going down the Maven path instead of setting all these environment variables? If using this, I would like to have some reference to Ant to be added to the file name. The Maven build only needs one environment variable set (currently ... hopefully this will be removed in the near future and we will be able to run with no environment variables at all)
