> In Groovy 2.5, {{groovy.util.CliBuilder}} is a wrapper that delegates to {{groovy.cli.commons.CliBuilder}}. However, this wrapper doesn't correctly handle the case when the arguments fail to be parsed.
> Here's how it works with the real {{CliBuilder}}:
> {code:java}
> groovy:000> options = new groovy.cli.commons.CliBuilder(stopAtNonOption: false).parse(['-x'])
> error: Unrecognized option: -x
> usage: groovy
> ===> null{code}
> And here's what happens with the wrapper:
> {code:java}
> groovy:000> options = new groovy.util.CliBuilder(stopAtNonOption: false).parse(['-x'])
> error: Unrecognized option: -x
> usage: groovy
> ===> groovy.util.OptionAccessor@6fc3e1a4
> groovy:000> options.arguments()
> ERROR java.lang.NullPointerException:
> Cannot invoke method arguments() on null object{code}
> I get an object that pretends to be {{null}}, but isn't. So I can't determine whether the parsing was successful or not.
