Trying to dynamically build a list of package names

[Chris Stillwell]

I am trying to dynamically build a list of package names to subsequently
feed into a javadoc task.
Here is the task I am trying so far:

  <target name="pkglist">
    <apply executable="echo" type="dir" dest="." output="pkglist.out" >
      <srcfile/>
      <fileset dir="$src" excludes="**/SCCS" includes="com/wcom/nw/**"/>
      <mapper type="identity"/>
    </apply>
    <replace file="dirlist.out" token="${src}/" value=""/>
    <replace file="dirlist.out" token="/" value="."/>
  </target>

This works pretty well with the exception that it includes higher level
directory names that I would like excluded because they are empty and cause
javadoc to terminate.
Example output:

com.wcom.nw                     <-- empty
com.wcom.nw.core                <-- empty
com.wcom.nw.core.lookup
com.wcom.nw.core.lookup.entry
com.wcom.nw.core.service
com.wcom.nw.core.log
com.wcom.nw.tools               <-- empty
com.wcom.nw.tools.browser
com.wcom.nw.service

Any ideas on how to eliminate these empty directories or is there a better
approach that I haven't thought about?


Thanks,

Chris
