    Description

      After update from Groovy 2.5.x to 3.0.0, scripts using picocli are failing with the following error:

      NoClassDefFoundError: picocli/CommandLine$ParameterException

      Here's a small example showing the problem:

      import groovy.cli.picocli.CliBuilder
      
      def cli = new CliBuilder(name: 'cliTest.groovy')
      cli.h(type: Boolean, longOpt: 'help', usageHelp: true, required: false, 'Show usage information')
      cli.c(type: String, longOpt: 'config', required: true, args: 1, 'Path to config file (required)')
      def opts = cli.parse(args)
      opts || System.exit(1)
      if(opts.h) {
        cli.usage()
        System.exit(0)
      }
      
      println(opts.c)
      

      Running this with Groovy 2.5.7 works:

      % ~/tmp/groovy-2.5.7/bin/groovy ./cliTest.groovy -c data/config_prod.yaml 
      data/config_prod.yaml

      But with 3.0.0, it does not:

      % ~/tmp/groovy-3.0.0/bin/groovy ./cliTest.groovy -c data/config_prod.yaml
