Delete task should be failing for UNC path that does not exist
The following reduced test case shows the problem. I've tested this with Ant
1.7.1 and JDK 1.4.2_19
=======================
<project name="delete-UNC-test">
<property name="out.parent.dir"
value="\\my-unc-path-that-does-not-exist\tmp"/>
<delete dir="${out.parent.dir}" verbose="true"/>
</project>
=======================
Can anyone help me with this?

It doesn't fail when the directory exists or does not exist.
However, when the directory does exist, it is not deleted.
It should either succeed and deleted the directory, or fail if it can't
delete the directory or the directory does not exist.
However, it's succeeding for all cases.

Does it fail when the directory does exist?
Try printing out "out.parent.dir" and see what it is equal to:
<echo message="out.parent.dir = "${out.parent.dir}""/>
Maybe the backslashes are being misinterpreted somehow.
Another possibility has to do with the way UNC paths work. Ant may not
be playing so friendly with them. It could be that Ant is receiving
the message that the path exists before it tries a delete, but then
when it tries a delete, it gets the deletion failed message. I am not
a Windows developer, so I can't say for certain what is going on.
You might want to try the <available> command to test for the
directory before doing the delete as a workaround.

The manual is right, and my memory is faulty, that's all ;-) I think I
always use quiet="true"... --DD

According to the Ant Manual,
In relation to the quiet attribute of the delete task..
"If the specified file or directory does not exist, do not display a
diagnostic message (unless Ant has been invoked with the -verbose or
-debugswitches) or modify the exit status to reflect an error. When
set to "true",
if a file or directory cannot be deleted, no error is reported. This setting
emulates the -f option to the Unix *rm* command. Setting this to "true"
implies setting failonerror to "false". "
Going by the first line of this, Ant should fail if the specified file or
directory does not exist, no?

I think that's true of any dir, not just UNC ones. --DD

You need to set failonerror="true" to kill the build when the delete
fails. Of course, Ant is depending upon the OS to give it a "proper"
exit value from the delete command. I can't say for certain whether
UNC paths might be cause problems in this respect.
BTW, why are you using UNC anyway. Normally, you don't do things in
Ant outside of the ${basedir}.

Hey guys,
I had made a mistake in my test script to see if it failed when trying to
deleted a directory that does exist.
It does indeed fail, likely due to access permissions, as I cannot delete
the file through explorer either.
However, I'm still curious as to why delete is silent when the UNC path
passed to it does not exist?

UNC paths are so troublesome...
You could try with <property location=""> instead of using the value attribute.
If that doesn't work, you could force the script user(s) to map it to
a drive letter.
If that doesn't work, resort to <exec> using the DOS "cmd" shell as
executable and using a DOS command to delete the dir (if you use
absolute UNC paths, you're likely Windows only, no? If not, the os
attribute of Exec can restrict the <exec> for a specific OS like
windows).
