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

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?
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.
