It sure would be nice, but since it isn't you're left doing it the long, and
complicated, way. That is, creating additional targets with dependencies and
conditions to get the desired conditional behavior. The property can be set as
follows.
<target name="mod_classdir.check">
<condition property="mod_classdir.exists">
<available file="${mod_classdir}" type="dir"/>
</condition>
</target>

Subject: Re: fileset fails when base dir is missing
That's a clever hack, but it won't work well in my situation, since some
of the filesets may be rooted in directories that cannot be created.
Wouldn't it be nice if the <fileset> tag had an attribute that allowed you
do say, "It's OK if it doesn't exist"? Something like this:
<fileset dir="somedir" if-base-dir-is-missing="ignore">...</fileset>
Anyone else have a good idea?
