将Java项目变成可运行的东西[重复]

Question

我在我就读的大学的成像系工作，我们要做的一件事就是在处理票证时不断复制/粘贴这些罐头回复，然后用票证的特定信息填充所有空白处.这足以激发我在空闲时间制作一个 java 项目来生成这些响应并填写所有信息以节省一些时间/练习编码。

在这个项目中有两个类，一个包含我的所有票证信息，另一个运行程序的主要部分（分别为 Ticket.java 和 ThingThatWork.java）。

票务.java

ThingThatWorks.java

package quickResponse;

public class ThingThatWorks {

    public static void main(String[] args) {
        Ticket newTicket = new Ticket();
        boolean imageOrReimage = false;
        String desktopOrLaptop = "";
        imageOrReimage = newTicket.imageOrReimage();
        newTicket.ticketInfo(imageOrReimage);
        
        if(imageOrReimage == true) 
            desktopOrLaptop = newTicket.desktopOrLaptop();
        
        System.out.println();
        System.out.println(newTicket.generateTitle(imageOrReimage));
        System.out.println();
        System.out.println(newTicket.generateMessageBody(imageOrReimage, desktopOrLaptop));
        System.out.println();
        System.out.println("---------------------------");
        System.out.println(newTicket.generateWorkNotes(imageOrReimage));
        
    }

}

我希望能够将其转换为可运行的 JAR 或 .exe 文件，以便在制作票证时可以在工作计算机上运行它。不幸的是，我看的 youtube 视频不清楚，当我从 Eclipse 将项目导出为可运行的 .jar 文件时，它给了我一个非特定的 JNI 错误（发生了一个 JNI 错误，请检查您的安装并重试）和一个非特定的 Java 异常错误（发生了一个 Java 异常）。我不确定我哪里出错了，我也不确定我是否在我的代码中编写了所有我需要的东西来抛出一个 cmd 窗口，让我输入我需要的东西，然后挂在那里足够长的时间让我复制它。

任何帮助，将不胜感激。

编辑：当我意识到我是在 Java 17 中编写它然后通过 Java 8 编译它时，设法让错误消失。我安装了 Java 17，重新导出了程序，现在它在运行时什么都不做，而不是给我错误。

我尝试过的一件事是通过命令行运行它，但无论我做什么，它都会给我错误“无法访问 jarfile”

编辑2：亚当的最初答案最终成为关键，当它编译为java 17时，我试图将它作为java 8运行。在确保我使用的是正确的版本而不是过时的安装后，我设法让程序运行从命令行。

谢谢大家的帮助

Answer 1

好的，编译时尝试以下操作：

1. 打开命令行并使用 cd 命令切换到包含 java 和 class 文件的目录
2. 运行命令

   fsutil 文件 createnew manifest.man 0

   3. 打开创建的清单并添加以下内容：

   清单版本：1.0

   主类：Java程序

   创建者：1.8.0_144（甲骨文公司）

   4. 返回命令行并运行命令

   jar cmf manifest.man Program.jar *.class

   5. 完成。您可以使用命令运行它

   java -jar Program.jar

   或者

   java -cp Program.jar ProgramJava
