整个夏天，我做了一个小型的文字游戏，但是直到大约两周前，它都没有制作.jar文件。它使用 Page 和 Paragraph 这两个类从.txt文件中读取大量文本行。
我已经在BlueJ中反复运行主类（userMendacious），并且该类始终运行且没有错误。但是，当我尝试将整个项目（包含.txt文件，所有上述类以及一些无关的未使用的.txt文件）导出为.jar文件时，出现“发生Java异常”错误。这是我正在执行的类的代码：
import java.util.*;
import java.io.*;
public class userMendacious {
public static void main (String[] args)
throws FileNotFoundException{
System.out.println ("Loading text...");
File textLoader = new File("C:\\Users\\Gage.Desktop-PC\\Documents\\Finished Games\\userMendacious\\everyPage.txt");//File containing all game text in the form of Pages
Scanner everyPage = new Scanner(textLoader);//Loads pages from everyPage.txt
Scanner interactor = new Scanner (System.in);//Scanner for user input
Scanner cheatHere = new Scanner (new File("cheatHere.txt"));
Page screens[][] = new Page[4][4];//Array storing pages
Boolean won = false;
int x = 0;
int y = 0;
int[] height = new int[4];//stores previously-held y-values on each tab
boolean[][] CRAPTCHASolved = new boolean[4][4];
String[][] CRAPTCHASolutions = new String[4][4];//No cheating now (make code to fill this array with Strings representing CRAPTCHA solutions)
String u = ("left");
String v = ("forward");
String s = ("right");

int failurepoints = 0;

对此感到奇怪的是，A。我知道这不是在BlueJ Terminal中发生的FileNotFoundException，B..jar文件同时导出并在相同版本的Java中运行，并且C.附加类，只有一种方法可以打印出预定的文本行，并且在导出时具有相同的问题。
