onCommand does not work

Hi Guys, I have a small problem. I want to trigger something when someone writes "/cw". But everytime I try it out is says the command doesn't exist, anyone knows why?

Code:

public boolean onCommand(CommandSender sender, Command cmd, String commandLabel, String[] args)
     {
         if(sender instanceof Player)
         {
             Player player = (Player) sender;
             player.sendMessage("hi");
             String command = cmd.getName();
             String[] arguments =  null;
             String helpMessage = "ChangeWeather is activ. Try out rain/sun.";
             if(command.equals("cw") && args.length > 0)
             {
                   //What to do
             }
         }
         return true;
     }

 

@Zero9195: you probably typed something like /Cw or /CW ..
cmd.getName() needs to be lowercased. In addition you plugins.yml must contain this command.

Code:

plugin.yml
..
..
commands:
    cw:
        description: This does something useful
        usage: |
            /<command> syntax - Desribe me

---

String command = cmd.getName().toLowerCase();
if (command.equals("cw") && args.length > 0) {
    // do something
} else if (command.equals("cw") && !args.length) {
    // show help
}

 

To fix the capitalization issues, use .equalsIgnoreCase().

 

Thanks, didn't Know about the Plugin.yml
