Is there a good options parser framework/library for command-line programs written in Java? E.g. the equivalent of Python's optparse?

Check these out:
http://commons.apache.org/cli/
http://www.martiansoftware.com/jsap/
And, to roll your own:

Take a look at the Commons CLI project, lots of good stuff in there.

Maybe these
JArgs command line option parsing suite for Java - this tiny project provides a convenient, compact, pre-packaged and comprehensively documented suite of command line option parsers for the use of Java programmers. Initially, parsing compatible with GNU-style 'getopt' is provided.
ritopt, The Ultimate Options Parser for Java - Although, several command line option standards have been preposed, ritopt follows the conventions prescribed in the opt package.

I've used JOpt and found it quite handy: http://jopt-simple.sourceforge.net/
The front page also provides a list of about 8 alternative libraries, check them out and pick the one that most suits your needs.

Yeap.
I think you're looking for something like this: http://commons.apache.org/cli
The Apache Commons CLI library provides an API for processing command line interfaces.

if you are familiar with gnu getopt, there is a java port at: http://www.urbanophile.com/arenn/hacking/download.htm. there appears to be a some classes that do this: http://docs.sun.com/source/816-5618-10/netscape/ldap/util/GetOpt.html, http://xml.apache.org/xalan-j/apidocs/org/apache/xalan/xsltc/cmdline/getopt/GetOpt.html

You might find this meta-article of unhappiness interesting as a jumping off point:

That guy is pretty useless "Commons CLIApparently the oldest of the options here, and doesn't get a lot of respect from commenters, so I didn't really look at this very closely..", but thanks for the link anyway.

Take a look at the more recent JCommander: http://beust.com/jcommander
(I created it, happy to answer questions or take feature requests)

I like your slogan: "Because life is too short to parse command line parameters"

Using it now and loving it! I would like to see automatic parsing of the - and -- for single char vs string arguments. i.e. "h" vs "-h" and "help" vs "--help"

Glad you like JCommander :-) I didn't want to add too much semantic to how the flags are treated, so you just need to add synonyms in the annotations you use:@Parameter(names = { "-h", "--help" })I thought it's a reasonable compromise.
