task to delete nonmatching files?

My build script currently has a task in it that copies files from one
directory to another changing the extension, using a file mapper.  This works
great.  Now the problem I have is that if I delete a file in the source
directory I'd like to have ant delete the file in the destination directory
the next time it builds, but only for files that are missing because it'd get
really expensive to delete all the files and do a full rebuild.  Has someone
already done this, or do I need to write my own task?

I see, it should work for general trees.  Upon first look it seemed that 
it'd only work if the files were in the same directory, which I also 
need.  Thanks.

I'm not sure what you mean. The way it currently works is that they're in
different subdirs under the base directory, just because that's the way I
assumed you'd be doing it -- there's nothing special about that fact. If
that's not case, then you'd just set your source and destination directory
properties to point to where they do exist (ie., in my example ${src.dir}
and ${dest.dir}). I assume the subdir hierarchy of the copied files is
kept, since you didn't mention flattening it.

Thanks.  What about if the files are in different trees?

Oops, unused var -- you can get rid of it.

Didn't write you a task, since it's faster for me to do it in Javascript
(anything to avoid doin' the dishes :)

 <property name="src.dir" location="src"/>
 <property name="dest.dir" location="dest"/>
 <target name="sync">
   <fileset dir="${dest.dir}" id="chkfiles">
     <include name="**/*.ship"/>
   </fileset>
   <pathconvert pathsep="," property="chkfiles" refid="chkfiles">
     <map from="${dest.dir}" to=""/>
   </pathconvert>
   <script language="javascript"> <![CDATA[
     importClass(java.io.File);
     importClass(java.util.StringTokenizer);
     var srcdir = projname.getProperty("src.dir");
     var destdir = projname.getProperty("dest.dir");
     var files = projname.getProperty("chkfiles");
     var filesep = projname.getProperty("file.separator");
     var st = new StringTokenizer(files, " ,");
     while (st.hasMoreTokens()) {
       var filename = st.nextToken();
       var pos = filename.indexOf('.');
       chkfilename = filename.substring(0, pos);
       chkfilename = srcdir.concat(chkfilename).concat(".orig");
       var chkfile = new File(chkfilename);
       if(!chkfile.exists()) {
         filename = destdir.concat(filename);
         showit = projname.createTask("echo");
         showit.setMessage( "Deleting leftover file: " + filename );
         showit.execute();
       }
     }
     ]]>
   </script>
 </target>

$ ant sync
sync:
     [echo] Deleting leftover file: C:\TEMP\dest\dir1\c\foo.ship
     [echo] Deleting leftover file: C:\TEMP\dest\dir2\b\baz.ship

(Change the extensions to what yours really are, and change the "showit"s
to deletes.)
