Description

with the following configuration...

DefaultParser parser = new DefaultParser();
 Options opts = new Options();

Option pager = Option.builder(null)
 .longOpt("cmd")
 .hasArg()
 .numberOfArgs(Option.UNLIMITED_VALUES)
 .build();

opts.addOption(pager);

 
This works as long as the value of cmd is a single value.

$ myApp --cmd='less'

The following does not work, as soon as we add options to less

$ myApp --cmd='less -XFR'
Exception in thread "main" com.cevaris.ag4j.cli.AppArgsException: org.apache.commons.cli.UnrecognizedOptionException: Unrecognized option: -XFR

The following works, as long as we use a space to separate option & value, rather than using an =

$ myApp --cmd 'less -XFR'  # works
$ myApp --cmd='less -XFR'  # fails

Attempted to use .valueSeparator() with no luck.
