adding subversion revision to manifest

[Torsten Curdt <tc...@apache.org>]

I've come up with a simple maven plugin that adds
the subversion revision to the manifest. So with


     public static Map getJarRevisions() throws IOException {
         final String[] jars = System.getProperty 
("java.class.path").split(
                 System.getProperty("path.separator"));
         final Map revisions = new HashMap(jars.length);
         for (int i = 0; i < jars.length; i++) {
             final JarFile jar = new JarFile(jars[i]);
             final Manifest manifest = jar.getManifest();
             final String revision = (String)  
manifest.getMainAttributes().getValue("Revision");
             revisions.put(jars[i], revision);
         }

       return revisions;
     }

You know *exactly* what jars are in your path.
Only add it to your maven.xml like this:

   <postGoal name="jar:jar">
     <attainGoal name="revision:add"/>
   </postGoal>

It is currently available at:

  http://people.apache.org/~tcurdt/maven-revision-plugin.tgz

It's for maven1 but just wraps a simple class
so a version for maven2 should be pretty straight
forward.

If people think this is useful I am sure we can
improve it and put it somewhere properly.

Hi -

Is this available as a Maven2 plugin?

Thanks,
