How to create multiple new symbolic links using apache ant from a fileset?

The symlink task in ant either create a single, record existing, recreate existing, or delete a single symbolic link. I want to create symbolic links to all the files within a given directory within a different directory.

The simplest way to achieve it (in terms of coding) is with the help of antcontrib's For task

<for param="file">
  <path>
    <fileset dir="${src.dir}" includes="*"/>
  </path>
  <sequential>

    <basename property="@{file}.basename" file="@{file}">
    <symlink link="${dest.dir}/${@{file}.basename}" resource="@{file}"/>
  </sequential>
</for>

If you don't want the dependency on ant-contrib, you may try the following (Note: I did not test it at all):

  1. Create a couple of links manually in ${dest.dir}.
  2. Run in ${dest.dir}.

Now you have a template properties file that you will recreate with your build instructions:

<pathconvert pathsep="${line.separator}" property="file.list">
  <fileset dir="${src.dir}" includes="*"/>
</pathconvert>
<echo message="${file.list}" file="${file-list.file}" append="false"/>

Now massage the file with regexp filter

<copy file="${file-list.file}" tofile="${dest-dir}/.link.properties">
  <filterchain>
    <tokenfilter>
      <!-- I leave regex as an exercise to the reader -->
      <replaceregex pattern="..." replace="..." flags="..."/>
    </tokenfilter>
  </filterchain>
</copy>

Finally do symlink-recreate.

<symlink action="recreate">
  <fileset dir="${dest.dir}" includes=".link.properties"/>  
</symlink>
