What is the best way of parsing many complex command-line arguments in Java?

Question

I have used getopt in Python and was hoping there would be something similar in Java.

Please give a reason why your answer is better than the others.

I like this one so far as it was quite easy to get up and running with a simple download. The 50 line demo is all I needed to get started, and I easily found that I could parse POSIX-style or GNU-style. – Liam Oct 16 '08 at 11:00

this is a horrible answer, Java Simple Argument Parse (JSAP) is a much better library. This is a hideous library and is really deprecated. – Jan 05 '10 at 22:15
So, how is JSAP better than Commons CLI? The only differences I see are: 1. Extensible type handlers (Commons CLI plans to make them extensible, but currently only a fixed set is supported), 2. ability to default values from configuration files. – Chris Jester-Young Jan 05 '10 at 22:20

I use Jewelcli and it's quite good.

You can also find a discussion of different available libraries here.

Look at Java Simple Argument Parser. Very mature and feature complete argument parser for Java. JSAP
