Thanks. This helps. We came up with a solution based on your input...
<target name="main">
<fileset id="fs" dir="${dir}"/>
<condition property="dir_empty">
<length length="0">
<fileset refid="fs"/>
</length>
</condition>
<for param="file">
<path>
<fileset refid="fs"/>
</path>
<sequential>
<echo> This is a file: @{file}</echo>
</sequential>
</for>
<fail unless="dir_empty">${message}</fail>
</target>
The length is not compared to the number of file, but rather the sum of
the length of all the included file. Since we want the directory to be
empty, the length we are testing for is 0. If someone were to test for a
certain number of files, this would not work.
