unexpected MissingParameterException when a help-option is supplied

[waacc-gh]

The example from chapter 2.3, extended by an help-option (e.g. -?), fails if just the help-option is supplied:

@Parameters(hidden = true)  // "hidden": don't show this parameter in usage help message
List<String> allParameters; // no "index" attribute: captures _all_ arguments (as Strings)

@Parameters(index = "0")    InetAddress  host;
@Parameters(index = "1")    int          port;
@Parameters(index = "2..*") File[]       files;

@Option(names = "-?", help = true) boolean help;  // <-- added

Called just with "-?" leads to:
Exception in thread "main" picocli.CommandLine$MissingParameterException: Missing required parameter: port

Thanks for the bug report! Investigating...

Tracked it down to over-eager validation. This is now fixed in master.

I released picocli v0.9.6 for this.
Thanks again for the bug report!

Thanks for the fixing quickly.
And thanks for the nice tool - helps me much.
