Picocli: Recognition of Aliases for Subcommands

Created on 14 Aug 2018 · 6Comments · Source: remkop/picocli

The below mixture of 1 parent command with 1 sub-command with aliases fails to recognize subcommand aliases properly.

INPUT: cb t

Expected output:

Running Collabbook main command!
Create task

Actual output:

Unmatched argument: t
Usage: cb [-hV] [COMMAND]
Collaborate on tasks in your git repo from the terminal.
  -h, --help      Show this help message and exit.
  -V, --version   Print version information and exit.
Commands:
  task  Create task
  note  Create note

MWE

@Command(description="Collaborate on tasks in your git repo from the terminal.",
         name="cb", mixinStandardHelpOptions = true, version="")
public class Collabbook implements Callable<Void>  {

    public static void main(String[] args) {
        CommandLine cmd = new CommandLine(new Collabbook())
                .addSubcommand("task", new CreateTask());

        List<Object> result = cmd.parseWithHandler(new RunAll(), args);
    }


    @Override
    public Void call() throws Exception {
        System.out.println("Running Collabbook main command!");
        return null;
    }
}

@Command(description="Create task", name="task", aliases={"t"})
public class CreateTask implements Callable<Void> {

    @Override
    public Void call() {
        System.out.println("Create task");
        return null;
    }
}
