Thanks David! It works now!
I still do not understand what this have to do with empty directories?
I just wanted to rename files and not their containing directories - why should I have to think about the "includeEmptyDirs" property?
Again, thanks for your time, Adrian.

This one didn't work because doing mappings with a special tag (as
opposed to the mapper tag using the type attribute) wasn't introduced
until Ant 1.6.2, and Maven still uses Ant 1.5.3.
<!-- this line does not copy anything, only the ${dest.dir} is created (?) --> <ant:mapper type="glob" from="*.*" to="*.*.xml" /> According to the Ant docs, the glob type mapper can have at most one * in the from and the to attributes. Since this contains 2 in each, it makes sense that it doesn't work as desired.
<!--
this line appends ".xml" both to
files and directories (?)
-->
<and:mapper type="glob" from="*" to="*.xml" />
This makes sense because the glob mapper applies itself to everything in
the fileset, and the fileset said to include everything.
Since Ant sees itself as copying the directories with the .xml extension, you can prevent this by simply adding the includeEmptyDirs attribute to the copy element: <ant:copy todir="target" includeEmptyDirs="false"> <ant:fileset dir="src" /> <ant:mapper type="glob" from="*" to="*.xml" /> </ant:copy> The downside here is that it won't copy empty directories if you have any. If you do have empty directories, you would need to create a separate copy task to do this.
Hope this helps, ..David..

Hi all,
I have a ${src.dir} like: src/main/mylang +treeofpackages +file1.xxx +file2.xxx +file1.yyy ...
Now, I want to write a Maven goal to copy this directory structure into a ${dest.dir} while appending an ".xml" extension to all files (but not to directories).
I tried to use:
<ant:copy todir="${dest.dir}"> <!-- this line alone copies the directory structure and files as expected --> <ant:fileset dir="${src.dir}" />
<!-- this line has no effect (?) (from Ant's User Manual) --> <ant:globmapper from="*" to="*.xml" />
<!-- this line appends ".xml" both to files and directories (?) --> <and:mapper type="glob" from="*" to="*.xml" />
<!-- this line does not copy anything, only the ${dest.dir} is created (?) --> <ant:mapper type="glob" from="*.*" to="*.*.xml" />
<!-- this line works as expected :) --> <ant:mapper type="glob" from="*.xxx" to="*.xxx.xml" />
</ant:copy>
Is it possible to write this task using only one <ant:copy> task and without specifying a mapper for each source file extension?
Thanks for your time, Adrian.
