Thomas Neidhart commented on CLI-230:
-------------------------------------
Ok good, it is advised to ask questions first on the user mailinglist
([email protected]) with the prefix [cli].
The warnings you get when using the OptionBuilder are due to the fact that all
methods there are static. The 1.3 release will provide a different way to build
options using a Builder class in the Option class itself.
The problem with the required options list will need a fix though to prevent
such mistakes.

> Affects Versions: 1.2
> Environment: windows jdk1.6.0_21
> Reporter: Alexander Fast
>
> Having some problems setting options as required. Have I misunderstood the
> documentation?
> * In test1() the option is required but also supplied, I expect to get no
> exceptions.
> * In test2() the option is required but *not* supplied, I expect to get an
> exception.
> {code:java}
> public class Testing {
> public static void main(String[] args) {
> System.out.println("Begin test 1");
> test1();
> System.out.println("End test 1");
> System.out.println("Begin test 2");
> test2();
> System.out.println("End test 2");
> }
> private static void test1() {
> String[] args = new String[] { "--foo" };
> Options options = new Options();
> options.addOption("f", "foo", false, "");
> options.getRequiredOptions().add(options.getOption("foo"));
> GnuParser parser = new GnuParser();
> try {
> parser.parse(options, args);
> } catch (ParseException e) {
> // didn't expect to get MissingOptionException here
> System.out.println("ERROR: " + e.getMessage());

> private static void test2() {
