这个问题在这里已经有答案了：

我可以通过cmd运行.jar文件，但不能双击它们（7个答案）
上个月关门了。
我的扫雷器项目在ide中工作得很好，但是当我在eclipse中将is导出为“runnable jar file”并随后执行它时，它就不工作了。我的舱单.mf
我还尝试通过cmd导航到那里，并使用javac minesweeper.jar。
控制台说它找不到命令“javac”。
如果我把cd放入我的文件夹，只做java minesweeper.jar，它会说：“找不到或加载mainclass minesweeper.jar”
这是主方法所在的代码：

我可以通过cmd运行.jar文件，但不能双击它们
当已经有答案的时候再问这个问题。。

运行可运行jar的方法是 -jar 参数，例如。 java -jar Minesweeper.jar . 否则，它假定您指的是classpath环境变量上的类名，您不应该依赖它。
