Piotr Repetowski commented on CLI-189:
--------------------------------------

This is not a bug. First you should add help option to the group:
\\
\\
{code}
DefaultOptionBuilder obuilder = new DefaultOptionBuilder();
Option help = obuilder.withLongName("help").create();

group.withOption(help);

// Your code
{code}
\\
Kind regards.

>  parser.setHelpTrigger("--help");
>  parser.parseAndHelp(args);
