Pb with copy and present selector

[etienne_frejaville <et...@coface.com>]

Hello,

I'm trying desperately to overwrite files from a source directory if they exist in a target directory.
The source and target directory have not the same hierarchy, source is flat and directory has sublevels.

Example of hierarchy:

root/source/A.html
root/source/B.html
root/source/C.html
...

root/dest/x/A.html
root/dest/y/B.html
root/dest/y/C.html
...


and I want that the names of the files to copy are obtained from dest and copied from source to dest, i.e :

root/source/A.html copied on root/dest/x/A.html
root/source/B.html copied on root/dest/y/B.html
root/source/C.html copied on root/dest/y/C.html
....

In shell, it's easily done like that:

cd root/dest
for i in */*.html
do
 cp ../source/`basename $i` $i
done

With ant, I've tried:

(launched from root directory) :

		<copy todir="dest" verbose="true">
			<fileset dir="source">
			   <present targetdir="dest">
                                <mapper type="regexp" from="(.*)\\(.*).html$$" to="\2.html"/>
                           </present>
			</fileset>
		</copy>

But it doesn't copy anything.
Actually, I'm quite puzzled with fileset and mappers.
 
Any idea? I've found very little literature on that subject.

As a corollary question, is there any tool that allows debugging such tasks, showing what is matched on each task .?

Thanks in advance.
