How to echo the empty directories of a fileset ?
Hello. If I do something like this:
<copy todir="${destination.dir}" verbose="true" >
<fileset dir="${projects.dir}/" >
<include name="*" />
</fileset>
</copy>
and projects.dir has some empty directories, then those directories
will be copied to destination.dir .
Is this normal behavior? (It seems strange to me that a fileset would
contain empty directories)
And if that's the case, how can I echo the empty directories of a
fileset? I am familiar with this:
<pathconvert refid="my.fileset" property="my.files.list"> pathsep=","/>
<echo message="${my.files.list}"/>
But it only prints the files of the fileset, not the directories.
Regards,
Bruno

Isn't there a new task named resourcecount. Maybe you could use this in conjunction with a test and if the resourcecount is 0 then echo it is empty. Or am I missing what you are trying to do?

I meant possible in a straightforward, direct way. As I suspected, I
guess its not possible: it seems this knowledge that <fileset> has of
empty directories is kinda of a hidden thing that only <copy> (and
perhaps a few other tasks) can make use of.
That being the case, I would rather not try to workaround this quirk,
I'll rather use the other resource types instead, which hopefully are
"purer" in behavior. I took a better look at them, and it seems
wrapping a <fileset> around a <resources> removes the quirky behavior
(ie, keeping the hidden empty directories), so that's good enough for
me.
Thx anyway,
Bruno

Anything is possible... :) Off the top of my head nothing simple
springs to mind. The easiest thing would probably be to write a
custom selector (you can script them, if memory serves) to select
directories with no children.
A hack would be to copy a structure without including empty
directories, then compare for relative paths that exist in the source
structure and not the target structure, but that seems a little heavy
to me in terms of processing required.

The copy code is fine and is just to exemply how I found this fileset behavior.
What I want to know is exactly what the title says, how can I echo the
empty directories of a fileset? That is possible, right?

If you simply want to copy a fileset and not get empty directories,
<copy> has an includeemptydirs attribute which defaults to true.
