Subject RE: When is unless/if checked?
Date Thu, 15 Apr 2004 10:16:25 GMT
the order of execution is
- perform the "depends" targets
- check for if/unless
- perform the target according to the check

the if/unless attribute requires the name of a property, not a value.
So use 
   if="name" 
instead
   if="${name}"
(which could be  if="value"  :-)
