Java – only one parameter is required in Apache commons cli?

• Java

I just want to know if there is any method in the Apache commons cli library that specifies that a parameter must be provided?

For example I have 2 command line arguments, but must provide one (no more or no less)? I want IP or MSISDN, but not both, not both:

OptionBuilder.hasArg(true);
OptionBuilder.withDescription("Bla bla");
OptionBuilder.isrequired(false);
commandLineOptions.addOption(OptionBuilder.create("ip"));

OptionBuilder.hasArg(true);
OptionBuilder.withDescription("Bla bla");
OptionBuilder.isrequired(false);
commandLineOptions.addOption(OptionBuilder.create("msisdn"));

Thank you.

Solution

It looks like you want a required OptionGroup with two mutually exclusive option values Add the option group to commandlineoptions
