the deploy target is on each of the individual nukes componets.
so once you've executed build.bat/sh in the build directory, then you need to leave that dir and head over to each module that you want to install, starting w/ the nukes dir.
cwd = nukes/build
cwd = nukes/nukes
and the ear will be deployed. i'd imagine that could could start w/ say the bb module and deploy that first, b/c it would just give you a message saying it depends upon nukes.ear - i prefer to just always deploy nukes.ear first to be safe.
