Hello.
First of all, those are the examples from ant documentation:
Copy a directory to another directory
<copy todir="../new/dir">
<fileset dir="src_dir"/>
</copy>
Copy a set of files to a directory
<copy todir="../dest/dir">
<fileset dir="src_dir">
<exclude name="**/*.java"/>
</fileset>
</copy>
<copy todir="../dest/dir">
<fileset dir="src_dir" excludes="**/*.java"/>
</copy>
Copy a set of files to a directory, appending .bak to the file name on the fly
<copy todir="../backup/dir">
<fileset dir="src_dir"/>
<globmapper from="*" to="*.bak"/>
</copy>
Secondly, here is the whole documentation about copy task.
