我遵循了大约 10 个不同的教程,但似乎没有一个能奏效,我的可运行 jar 文件无法正常工作。
当我在 Eclipse 中运行游戏时,我的游戏运行良好,并且我能够将其制作成一个可运行的 jar 文件,该文件仅在一两天前工作并且没有更改太多代码。当我尝试运行 .jar 时,我的屏幕底部会弹出一个 java 图标,但随后什么也没有发生。
这是我的启动器无法打开(如果我在没有启动器的情况下运行它工作正常),无论我使用终端还是 Eclipse 打开都没有错误。

如果有帮助,我正在使用mac...
这是我采取的确切步骤的屏幕截图
我收到了一些警告(我认为它们只是因为未使用的变量,当我能够让我的 .jar 工作时,我早些时候收到了这条消息)
这似乎是我屏幕的顶部以及底部的 java 图标,但没有其他任何反应。
-谢谢
