我有2个类，第一个是Main，第二个是Config 这是Main类的代码：

package me.whispereq.colorCodes;
import org.bukkit.command.CommandExecutor;
import org.bukkit.plugin.java.JavaPlugin;
public class Main extends JavaPlugin implements CommandExecutor{
    public static Main instance;
    public static void s(String mg){
        System.out.println(mg);
    }
    public void onEnable(){
        instance = this;
        s("=======================================");
        s("         CHAT MANAGER MAIN");
        s("Loading Plugin chat manager by the whispereq");
        s("=======================================");
        getCommand("helpchat").setExecutor(new Config());
        saveDefaultConfig();
    }
    public static Main getInst(){
        return instance;
    }
}

Config类中的代码：

package me.whispereq.colorCodes;
import java.util.List;
import org.bukkit.Bukkit;
import org.bukkit.command.Command;
import org.bukkit.command.CommandExecutor;
import org.bukkit.command.CommandSender;
import org.bukkit.event.player.AsyncPlayerChatEvent;

public class Config implements CommandExecutor {
    public boolean onCommand(CommandSender s, Command cmd, String label, String[] args) {
        if ((cmd.getName().equalsIgnoreCase("helpchat")) && (args.length == 0)){
            s.sendMessage("§6-----------------------------");
            s.sendMessage("§cCommands:");
            s.sendMessage(" §7/help");
            s.sendMessage("§cFunctions");
            s.sendMessage(" §7Swear words replacement, blankfields");
            s.sendMessage(" §7Color codes, swear repl character,");
            s.sendMessage(" §cPlugin Includes COnfig File!");
            s.sendMessage("§6-----------------------------");
        }
        else if (args.length > 0){
            s.sendMessage("§4/help");
        }
        return false;
    }
    public static void onChat(AsyncPlayerChatEvent e){
        List<?> swear = Main.getInst().getConfig().getList("swearwords");
        String replacement = Main.getInst().getConfig().getString("sword-char");
        String warn = Main.getInst().getConfig().getString("sword-msg");
        List<?> blanks = Main.getInst().getConfig().getList("blankfields");
        String bfmsg = Main.getInst().getConfig().getString("use-msg");
        List<?> colors = Main.getInst().getConfig().getList("colorcodes");
        String cuse = Main.getInst().getConfig().getString("coloruse");
        if (e.getMessage().contains((CharSequence) swear)){
            e.getMessage().replace((CharSequence) swear, replacement);
            e.getPlayer().sendMessage(warn + Bukkit.getServerName());
        }
        else if (e.getMessage().contains((CharSequence) blanks)){
            e.getMessage().replace((CharSequence) blanks, "");
            e.getPlayer().sendMessage(bfmsg);
        }
        else if (e.getMessage().contains((CharSequence) colors)){
            e.getMessage().replace((CharSequence) colors, "§");
            e.getPlayer().sendMessage(cuse);
        }
    }
}

Config.yml文件：

###########################
#     Color Codes List    #
###########################
# Character, word #
colorcodes:
  - '&'

coloruse: §6You have used§4§l ColorCodes§6.

# swear word repalcement: char, word,
# sentence, or other things, with it will
# be replaced the serar word.
# INFO: you can make a swear word an
# BLANK FIELD.

请帮助我，这是一个大项目，我不知道它为什么不起作用。谢谢大家！ 〜whispereq

2 个答案:

答案 0 :(得分：3)

第一个错误表明，有两个或更多插件与主类具有相同的路径（相同的包+相同的类名） - Bukkit需要那些主类路径是唯一的。

第二个错误 - 该命令未添加到plugin.yml文件中，因此getCommand（）方法抛出了NullPointerException。

答案 1 :(得分：0)

第一个错误通常表示有多个具有相同名称的插件。

第二个错误指​​向Main.class中的第15行。 NullPointerException表示您使用的某个对象是null。

确保检查了所引用的每个对象，并确保它们不为空。
