java - 制作一个 jar list 。它从哪里来，我自己做吗？

Question

我最近创建了一个简单的 tic tac toe 程序，我一直在尝试将其放入 jar 中，并使用 cmd。我设法拿到了 jar ，但是当我点击它时什么也没有发生。经过更多研究后，我认为这是一个明显的问题，因为我没有对此做任何事情，甚至可以找到一个问题。现在这个 list 的事情真的让我很困惑，我已经多次创建了自己的 list 作为一个txt，但这不起作用，我读到它会创建它自己的 list ，但我在任何地方都找不到它。有人可以澄清一下这个 list 来自哪里或者如何创建一个。

list 文件:

主类:Tic_Tac_Toe.TicTacToe

Answer 1

如果您想将 list 文件添加到 jar 中，则必须使用 jar -cfm 命令。

例如，您有一个名为 Manifest.txt 的 list 文件，您希望将其添加到命令将是的 jar tictactoe.jar 中。

jar -cfm tictactoe.jar Manifest.txt *

如果您想提及主类，您必须在 list 文件中添加一个条目，如下所示。

Main-Class: <fully qualified name for the class>

还要检查 jar 文件的默认程序是否正确配置。

更新

您的 Java 类不在包中，因此您的 list 文件应该在包中。

Main-Class: TicTacToe 

如果您希望该类位于包中，请在导入语句上方的第一行中添加包package tictactoe;。 list 文件中应该是。

Main-Class: tictactoe.TicTacToe
