There isn't a built-in property for the target, but you could do something
in .antrc (which the 'ant' script processes):

for arg in $*
{
  [ "$targetset" ] && {
    echo "Error: Only one of production | test may be specified."
    exit 1
  }
  case $arg in
    production) export ANT_OPTS="$ANT_OPTS -Dtarget=$arg"
                targetset=true
                ;;
          test) export ANT_OPTS="$ANT_OPTS -Dtarget=$arg"
                targetset=true
                ;;
  esac
}

Of course, that's just for *nix (or Win* running *nix-type shells), so if
you're on a straight Win* box, you're on your own :)
