This is, imo at least, ugly. If the consensus is that this would be
something nice to fix in the 1.x tree (not sure if still an issue in
2.x), I'll open a JIRA and start work.
There is a workaround if you have only one required option:
Options options = ...;
Option requiredOption = ...;
requiredOption.setRequired(false);
Option help = ...;
help.setRequired(false);
OptionGroup requiredOptions = new OptionGroup();
requiredOptions.addOption(required);
requiredOptions.addOption(help);
requiredOptions.setRequired(true);
options.addOptionGroup(requiredOptions);
but this doesn't work if you have more than one required option.
