Description

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.

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() {

        String[] args = new String[] { };

        Options options = new Options();
        options.addOption("f", "foo", false, "");
        options.getOption("f").setRequired(true);

        GnuParser parser = new GnuParser();
        try {
            parser.parse(options, args);
        } catch (ParseException e) {
            // expected to get MissingOptionException here
            System.out.println("ERROR: " + e.getMessage());
        }
    }
}
