Re: How to hide output of an -- DON'T use spawn=true
Oops,
Look like the "spawn" attribute route won't work :-)
With "spawn=true" the <exec> task does NOT "block" and
wait for the executable to finish. I need to have the
script proceed only after the execuatable is finished,
so we down to the <redirector> and/or moving to 1.6.3

Ninju: I wrote the redirector stuff a year ago and to
my chagrin only just discovered that refid'd
redirectors do not work! A huge bug that will be
fixed in CVS within the hour, and will be in Ant 1.6.3
. I will post an example after the bug is fixed.
Thanks,
Matt
