Description

I want to ad check if Options which marked as Required are available or not 

My use case is to have a method like below in CommandLine class

boolean hasAllRequiredOptions()

 Check below given expected code, (code kept uncompiled purposefully)

import org.apache.commons.cli.*;

public class CLITester {
    public static void main(String[] args) throws ParseException {

        Options options = new Options();
        options.addRequiredOption("p", "print", false, "Send print request to printer.")
                .addRequiredOption("g", "gui", false, "Show GUI Application")
                .addOption("n", "nothing", true, "No. of copies to print");

        CommandLineParser parser = new DefaultParser();
        CommandLine cmd = parser.parse(options, args);
        if (!cmd.hasAllRequiredOptions()) { // I want to have method like this which will check if all required options are available

            HelpFormatter formatter = new HelpFormatter();
            formatter.printHelp("CLITester", options);
        }
    }
}
