Add a copyright notice to all files in a directory using Ant

Question

Hi! I want to add a copyright notice to a series of files generated in an Ant build. What's the easiest way to do it?

I thought about using <concat> but I don't understand how to run it on a fileset without concatenating all the files in the fileset.

Thanks!

Answer 1

One option might be to use <concat> but within an antcontrib <foreach> task.

Answer 2

If you only want to selectively add the copyright the use a copy command that replaces @COPYRIGHT@ tokens within the files.

  <copy todir="../backup/dir">
    <fileset dir="src_dir"/>
    <filterset>
      <filter token="COPYRIGHT" value="This text is my copyright!"/>
    </filterset>
  </copy>

Looks like <concatfilter> may be your friend.

<echo message="/* Copyright text */${line.separator}" file="copyright.txt"/>

<copy todir="dest_dir">
  <fileset dir="src_dir"/>
  <filterchain>
    <concatfilter prepend="copyright.txt"/>
  </filterchain>
</copy>
