[GROOVY-8307] CliBuilder problem with multi-argument option if last

• Type: Bug
• Status: Open
• Priority: Major
• Resolution: Unresolved
• Affects Version/s: 2.4.12
• Component/s: groovy-jdk
• Environment: Ubuntu 15.04; JVM 1.8.0.121 (Oracle)

Description

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 code and examples below, inserting a no-argument option in between the -m and the parsed arguments causes the problem to go away.

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()}"

Usage:

> 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]
