Minecraft 1.15.2中的Modded命令在给定参数时总是显示未知命令

Question

我目前正在尝试为1.15.2开发一个简单的Minecraft mod。我试图创建的是一个命令，匿名你的消息，例如在假选举期间。它基本上接受您编写的消息，并将其匿名发送给服务器中的每个人。

下面是处理该行为的命令类的代码：

public class CommandVote {
    public static void register(CommandDispatcher<CommandSource> dispatcher) {
        LiteralArgumentBuilder<CommandSource> builder = Commands.literal("vote").requires(source -> source.hasPermissionLevel(0));
        builder.executes(context -> vote(context))
                    .then(Commands.argument("message", MessageArgument.message()))
                        .executes(context -> voteArgs(context));
        dispatcher.register(builder);
    }

    private static int vote(CommandContext<CommandSource> context) throws CommandSyntaxException {
        ServerPlayerEntity player = context.getSource().asPlayer();
        player.sendMessage(new StringTextComponent("Por favor, introduzca su opcion en la votacion"));
        return Command.SINGLE_SUCCESS;
    }

    private static int voteArgs(CommandContext<CommandSource> context) throws CommandSyntaxException {
        ServerPlayerEntity player = context.getSource().asPlayer();

        player.server.getPlayerList().sendMessage(MessageArgument.getMessage(context, "message"));
        return Command.SINGLE_SUCCESS;
    }
}

谢谢你的提问！这可以更好地作为top函数的主体：

LiteralArgumentBuilder<CommandSource> builder = Commands.literal("vote")
                .then(Commands.argument("number", IntegerArgumentType.integer())
                        .then(Commands.argument("message", MessageArgument.message())
                                .executes(context -> {
                                    System.out.println("Level 3 " + context.getInput());
                                    return Command.SINGLE_SUCCESS;
                                }))
                        .executes(context -> {
                            System.out.println("Level 2 " + context.getInput());
                            return Command.SINGLE_SUCCESS;
                        }))
                .executes(context -> {
                    System.out.println("Level 1 " + context.getInput());
                    return Command.SINGLE_SUCCESS;
                });
dispatcher.register(builder);
