Description

When stopAtNonOption: false flag is set, the two versions of CliBuilder behave differently. (See GROOVY-8740)

The commons cli version of CliBuilder returns null:

def optCommons = new groovy.cli.commons.CliBuilder(stopAtNonOption: false).parse(['-x'])
if (optCommons) println "Okay" else println "Error"

The picocli version of CliBuilder returns a non-null options object with the "-x" value as a positional parameter:

def optCli = new groovy.cli.picocli.CliBuilder(stopAtNonOption: false).parse(['-x'])
if (optCli) println "Okay" else println "Error"
