我最近创建了一个简单的tic tac toe程序，我一直试图将它变成一个jar并使用cmd。我设法拿到了罐子，但是当我点击它时没有任何反应。经过更多的研究后，我认为这是一个明显的问题，因为我没有做任何事情，甚至可以找到一个。现在这个显而易见的事情让我很困惑我已经创建了我自己的清单几次只是一个txt，但是这没有用，我读到它会创建它自己的清单，但我找不到任何地方。有人可以澄清这个清单来自或如何创建一个。

您使用的是IDE吗？如果是这样的话，大多数IDE都可以选择直接将Java程序导出为创建了Manifest的jar。您在META-INF / MANIFEST.MF文件中需要的是主路径和类路径中的任何依赖库。
在MANIFEST.MF文件中添加以下内容：
Main-Class: com.example.MainClass
Class-Path: lib/library.jar
使用Main-Class中的main方法和Class-Path中的任何依赖库提供类的完整路径。
现在你可以尝试创建jar了。
答案 1 :(得分：1)
如果要将清单文件添加到jar，则必须使用jar -cfm命令。
例如，您有一个清单文件名Manifest.txt，您希望将该命令添加到您的jar tictactoe.jar中。
jar -cfm tictactoe.jar Manifest.txt *
如果你想提及主类，你必须在清单文件中添加一个条目，如下所示。
Main-Class: <fully qualified name for the class>
同时检查jar文件的默认程序是否已正确配置。
<强>更新
您的Java类不在包中，因此您的清单文件应该是。
Main-Class: TicTacToe
如果您想要一个包中的类，那么在import语句上方的第一行添加包package tictactoe;。清单文件应该是。
Main-Class: tictactoe.TicTacToe
