LinuxQuestions.org - Java + Ant - multiple Jar update

I have a single file that I wish to place in multiple, existing Jar files. The problem is that the number of Jar files will be growing significantly and I do not wish to copy-and-paste the Ant script pieces each time one appears.

The update I am currently using is this (roughly):

Code:

<jar jarfile="${my.jar.file.1}" update="true">

  <fileset file="${my.extra.info}" />

</jar>

<jar jarfile="${my.jar.file.2}" update="true">

  <fileset file="${my.extra.info}" />

</jar>

I would hate to reinvent the wheel and create a custom Ant task for this, so I would like to know if there is some way to do something similar to this (I could not find anything after Googling for a little while):

Code:

<jar update="true">

  <jars dir="${my.jar.dir}" includes="**/*.jar" />

  <fileset file="${my.extra.info}" />

</jar>
