I've tested this now under Ant 1.6.5, and on two different platforms;
the same bug is present. Can anyone confirm this bad behavior on
their own system? If there are no objections, I think I'll create a
bug report.
For comparison, here is a full script that works correctly (notice
that the only difference is in the "uptodate" command):
<project name="test-uptodate2">
<target name="update-source" >
<touch file="source" />
<echo message="Source updated. Target is out of date." />
</target>
<target name="update-target" depends="check-generate"
unless="generated" >
<delete dir="target" />
<mkdir dir="target" />
</target>
<fileset id="source-files" dir="${basedir}" includes="source" />
<target name="check-generate">
<uptodate property="generated" targetfile="target"
srcfile="source" />
</target>
</project>

uptodate does not seem to handle target directories properly. It
will incorrectly determine that a generated directory with an out-
of-date timestamp is actually up to date. Example script:
<project name="test-uptodate">
<target name="update-source" >
<touch file="source" />
<echo message="Source updated. Target is out of date." />
</target>
<target name="update-target" depends="check-generate"

<mkdir dir="target" />

<fileset id="source-files" dir="${basedir}" includes="source" />
<target name="check-generate">
<uptodate property="generated" targetfile="target">
<srcfiles refid="source-files" />
</uptodate>
</target>
</project>
If, in an empty directory, I do the following:
- ant update-source (to generate the source file)
- ant update-target (to generate the target directory)
- ant update-source (to change the timestamp on the source file)
- ant update-target (to generate a *new* target directory)
On the second "update-target" uptodate incorrectly determines that
the directory is up to date.
If I modify my script to do the following:
<uptodate property="generated" srcfile="source"
targetfile="target" />
it will work as expected.
It also works as expected if I generate a target *file* instead of
a target *directory*.
I'm using Ant 1.6.2 and Java 1.5.0_05.
