I see that it upgrades from commons-cli 1.2 to 1.4

 

Code snippet…

I’m dynamically trying to build default command line options for my scripting framework.

This works in 2.4

 

        // validate the option

        Integer slen = map.opt.length() // short opt length

        Integer llen = map.longOpt.length() // long opt length

        if (slen > 1 || llen == 1 || (slen == 0 && llen == 0)) {

            log.warn "invalid cli opt definition [$config]"

            return

        }

        if (slen) {

            if (builder.options.getOption(map.opt)) {

                log.warn "opt already used [$config]"

                return

            }

        }

        if (llen) {

            if (builder.options.getOption(map.longOpt)) {

                log.warn "longOpt already used [$config]"

                return

            }

        }

        // add the option

        Map builderOption = [:]

        if (llen > 0) {

            builderOption.longOpt = map.longOpt

        }

        if (slen > 0) {

            builderOption.opt = map.opt

        }

        if (map.argName) {

            builderOption.args = 1

            builderOption.argName = map.argName

        }

        builder."${map.opt ?: '_'}"(builderOption, map.desc)  // problem is here
