    • Component/s: Grape

      Description

      (Issue originally raised as: https://github.com/remkop/picocli/issues/970)

      Consider the following minimal script:

      @Grab('info.picocli:picocli:4.2.0')
      import groovy.cli.picocli.CliBuilder
      
      def cli = new CliBuilder()
      

      Under Groovy 2.5.9, this runs without error; with 3.0.1, however, I see:

      $ groovy cli.groovy 
      Caught: java.lang.NoClassDefFoundError: picocli/CommandLine$ParameterException
      java.lang.NoClassDefFoundError: picocli/CommandLine$ParameterException
      at cli.run(cli.groovy:4)

      Caused by: java.lang.ClassNotFoundException: picocli.CommandLine$ParameterException
      ... 4 more
      

      The jar is definitely downloaded to ~/.groovy/grapes and both versions of Groovy output

      Resolving dependency: info.picocli#picocli;4.2.0 {default=[default]}
      Preparing to download artifact info.picocli#picocli;4.2.0!picocli.jar
      

      when -Dgroovy.grape.report.downloads=true is supplied.
