how to ship all license.txt files

[torsten . reinhard]

Hi, 

when we ship our product, we have to ship also all used 3rdParty licenses.
Is there a way to detect the license.txt files automatically?
Extract those files from all dependencies, for example?

Or do I have to enumerate all licenses in my pom.xml

  <licenses>
    <license>
      <name>....</name>
      <url>.....</url>
    </license>
  </licenses>

These plugins are NOT what I´m looking for:

1) http://code.google.com/p/maven-license-plugin/

2) http://mojo.codehaus.org/rat-maven-plugin/

thanx for any advice, 

Torsten
