Rob--are you using Ant 1.7? Somehow when this first
came through I went brain dead and didn't give you the
easy answer.
<!-- condition: -->
<resourcecount count="0" refid="fs" />
Note that a pre-1.7 compatible way of testing the
number of files returned might start:
<pathconvert refid="fs" property="countme" pathsep="">
<mergemapper to="x" />
</pathconvert>
<!-- plus condition: -->
<length length="0" string="${countme}" />
HTH,
Matt
