Probably the state-of-the-arg is args4j:

  https://args4j.dev.java.net/

It uses Java 5 annotations to setup the argument parsing:

  public class SampleMain {

    @Option(name="-r",usage="recursively run something")
    private boolean recursive;

    @Option(name="-o",usage="output to this file",metaVar="OUTPUT")
    private File out = new File(".");

    @Option(name="-str")        // no usage
    private String str = "(default value)";
  ...

I'm usually not a big fan of reflection, but it may make sense to take advantage of it in a case like this, and just import args4j into our command line tools.

args4j is provided under the MIT license.
