PIRC機器人代碼中我在做什么錯？

Question

我不斷收到這個錯誤

從下面的代碼。

import org.jibble.pircbot.*;
import org.jsoup.*;
import org.jsoup.helper.*;
import org.jsoup.nodes.*;
import org.jsoup.select.*;
import java.io.*;

public class MyBot extends PircBot {
    public MyBot() {
        this.setName("^MonstaBot^");
    }
    public void onMessage(String channel, String sender, String login, String hostname, String message) {
        if(sender.equalsIgnoreCase("monstarules") && message.equalsIgnoreCase("!quit")){
            quitServer("Good bye!");
        }
        if(message.equalsIgnoreCase("!pc.babel")) {
            String playerList = new String();
            Document doc = null;
            try {
                doc = Jsoup.connect("http://aos075.aloha.pk:34886/").get();
                String text = doc.html();
                FileWriter fw = new FileWriter("temp1.txt");
                fw.write(text);
                fw.close();
                BufferedReader br = new BufferedReader(new FileReader("temp1.txt"));

                for(int i = 0; i < 103; ++i)
                br.readLine();
                text = br.readLine();
                text = text.trim();
                text = text.replaceAll("<br>", "").replaceAll("<p>", "").replaceAll("</p>", "");
                text = text.replace("Hello! Welcome to the status server for aloha.pk tower of babel. ", "");
                int stlg = text.length() - 1;

                for(int i = (stlg - 22); stlg > i; i++) {
                    String tw = "" + text.charAt(i);
                    playerList = playerList + tw;
                }
                sendMessage(channel, playerList);
            }
            catch (IOException e) {
                e.printStackTrace();
            }
        }
    }
}

由於某種原因，我覺得這非常簡單。 我寫的有效的原始代碼是：

import java.io.*;
import org.jsoup.*;
import org.jsoup.helper.*;
import org.jsoup.nodes.*;
import org.jsoup.select.*;

public class Scraper {
    public static void derp() throws IOException {
        String playerList = new String();

        Document doc = null;
        try {
            doc = Jsoup.connect("http://aos075.aloha.pk:34886/").get();
        }
        catch (IOException e) {
            e.printStackTrace();
        }
        String text = doc.html();

        FileWriter fw = new FileWriter("temp1.txt");
        fw.write(text);
        fw.close();

        BufferedReader br = new BufferedReader(new FileReader("temp1.txt"));

        for(int i = 0; i < 103; ++i)
        br.readLine();
        text = br.readLine();
        text = text.trim();
        text = text.replaceAll("<br>", "").replaceAll("<p>", "").replaceAll("</p>", "");
        text = text.replace("Hello! Welcome to the status server for aloha.pk tower of babel. ", "");
        int stlg = text.length() - 1;

        for(int i = (stlg - 22); stlg > i; i++) {
            String tw = "" + text.charAt(i);
            playerList = playerList + tw;
        }
        System.out.print(playerList);
    }
    public static void main(String[] args) throws IOException {
        derp();
    }
}

原始代碼有效，但是，每當我嘗試使其成為一種方法並將其插入到botcode中時，我總是會收到錯誤，並且在糾正它們時，嘗試調用!pc.babel的觸發器時， !pc.babel彈出更多!pc.babel 。 誰能幫我理解錯誤？

此錯誤是鍵java.lang.NoClassDefFoundError: org/jsoup/Jsoup 。 這意味着Jsoup JAR不在您的應用程序類路徑上。 您如何啟動和運行您的機器人？ 這與您啟動和運行原始代碼有何不同？
