Command block doesn't have permission for my Bukkit command

How do I allow command blocks to do this command?



Code:

Code:

package me.bukkit.Roboi;

import org.bukkit.Bukkit;
import org.bukkit.ChatColor;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;

public class RSayCommand implements CommandExecutor {
  
    public static String color(String string) {
        return ChatColor.translateAlternateColorCodes('&', string);
    }

    public boolean onCommand(CommandSender sender, Command cmd, String label, String[] args) {
  
    if (cmd.getName().equalsIgnoreCase("rsay")) {
        if (!sender.hasPermission("r.say")) {
            sender.sendMessage(ChatColor.translateAlternateColorCodes('&', "&cNo permission!"));          
        }
        String myString = "";
        for(int i = 0; i < args.length; i++){
            String arg = args[i] + " ";
            myString = myString + arg;
        }

 

@Roboi Just check if the sender is a player, like this:

Code:Java

if (sender instanceof Player && !sender.hasPermission("r.say")) {
