-----------------------------------

             Summary: CliBuilder problem with multi-argument option if last
                 Key: GROOVY-8307
                 URL: https://issues.apache.org/jira/browse/GROOVY-8307
             Project: Groovy
          Issue Type: Bug
          Components: groovy-jdk
    Affects Versions: 2.4.12
         Environment: Ubuntu 15.04
JVM 1.8.0.121 (Oracle)
            Reporter: Alan Hengle


When a multi-argument option is passed as the last option, any arguments after that get absorbed
into it.  As you can see from the cod and examples below, inserting a no-argument option in
between the -m and the parsed arguments causes the problem to go away.

{code:java}
import org.apache.commons.cli.Option

CliBuilder cli = new CliBuilder(usage:"example of using multi-arg value")
cli.with {
    m(longOpt:'multiple-opts', args: Option.UNLIMITED_VALUES, valueSeparator: ';',
        "enter multiple values, separated by ';' (usage: -mval1;val2)")
    a(longOpt:'simple-arg', "simple argument")
    h("help")
}
// cli.stopAtNonOption can be true or false, same result
def opts = cli.parse(args)
if (opts.m)
    opts.ms.eachWithIndex { l,i -> println "$i: $l" }
println "arguments: ${opts.arguments()}"

{code}

Usage:

{code:java}
> groovy clibuilderError.groovy "-mhello;goodbye" arg1 arg2 arg3
0: hello
1: goodbye
2: arg1
3: --
4: arg2
5: arg3
arguments: []
> groovy clibuilderError.groovy "-mhello;goodbye" -a arg1 arg2 arg3
0: hello
1: goodbye
arguments: [arg1, arg2, arg3]
1
{code}
