文件的路径如下:

package com.tellidea;
public class Temp{
public static void main(String args[]){
System.out.println(args[0]);
}
}

直接vim myjar.jar 打开jar包,查看里面的内容:

MANIFEST.MF文件的内容:

---------------------------------------------------------------
Here it is in one line:
jar cvfe myjar.jar package.MainClass *.class
where MainClass is the class with your main method, and package is MainClass's package.
Note you have to compile your .java files to .class files before doing this.
