When I go to a directory and make a jar file in command prompt, it works correctly. But, when I am in dir1 and make a jar file from dir2, it makes the jar file in dir1 and the jar file has error :
当我转到目录并在命令提示符下创建一个jar文件时,它可以正常工作。但是,当我在dir1并从dir2制作一个jar文件时,它会使dir1中的jar文件和jar文件出错:
couldn't find main class.
找不到主要班级。
I thought it works if I change current directory by java code. If it works from command prompt, it will be correct in java code.
如果我用java代码更改当前目录,我认为它有效。如果它在命令提示符下工作,它在java代码中是正确的。
C:\Users\username\Desktop>jar cfe Main.jar Main F:\Java\Files\Main.class
C:\Users\username\Desktop>java -jar F:\Java\Files\Main.jar
Error: Could not find or load main class Main

You are specifying that the Main.jar be generated in the current directory. Include the full path of the jar file when you are generating it:
您指定在当前目录中生成Main.jar。生成时包括jar文件的完整路径:
C:\Users\username\Desktop>jar cfe F:\Java\Files\Main.jar Main F:\Java\Files\Main.class
