JCommander

This is an annotation based parameter parsing framework for Java.

Here is a quick example:

public class JCommanderTest {
    @Parameter
    public List<String> parameters = Lists.newArrayList();

    @Parameter(names = { "-log", "-verbose" }, description = "Level of verbosity")
    public Integer verbose = 1;

    @Parameter(names = "-groups", description = "Comma-separated list of group names to be run")
    public String groups;

    @Parameter(names = "-debug", description = "Debug mode")
    public boolean debug = false;
}

and how you use it:

CommanderTest jct = new JCommanderTest();
String[] argv = { "-log", "2", "-groups", "unit", "a", "b", "c" };
new JCommander(jct, argv);

Assert.assertEquals(jct.verbose.intValue(), 2);
