错误！ AppGameContainer抛出java.lang.ClassNotFoundException

Question

这是我的代码：

import org.newdawn.slick.*; 
import org.newdawn.slick.state.*; 

public class Game extends StateBasedGame{ 

    public static final String gamename = "Ham Blaster!"; 
    public static final int menu = 0; 
    public static final int play = 1; 

    public Game(String gamename) { 
     super(gamename); 
     this.addState(new Menu(menu)); 
     this.addState(new Play(play)); 
    } 

    public void initStatesList(GameContainer gc) throws SlickException{ 
     this.getState(menu).init(gc, this); 
     this.getState(play).init(gc, this); 
     this.enterState(menu); 
    } 

    //This create the window 
    public static void main(String[] args){ 
     AppGameContainer appgc; 
     try{ 
      appgc = new AppGameContainer(new Game(gamename)); 
      appgc.setDisplayMode(640, 360, false); 
      appgc.start(); 
     }catch(SlickException e){ 
      e.printStackTrace(); 
     } 
    } 

} 

这是它让我的错误：

exception in thread "main" java.lang.NoClassDefFoundError: org/lwjgl/LWJGLException 
    at JavaGame.Game.main(Game.java:28) 
Caused by: java.lang.ClassNotFoundException: org.lwjgl.LWJGLException

所以它让我的类没有发现错误，我试图再次添加罐子，但它仍然给我的错误。 所以请帮助我，我检查图书馆，它告诉我，班级在那里，但不是来源。

从旧LWJGL网站下载一个旧版本lwjgl.jar的，版本2.9.3 http://legacy.lwjgl.org/
