需求： 将一段代码，打成jar包， 使得’随处运行’  
测试代码如下：

import java.io.File;
    import java.io.FileOutputStream;
    import java.io.IOException;
    import java.util.Scanner;
    
    public class FileTest {
        public static void main(String[] args) throws IOException {
            //创建文件
            File file=new File("/home/wang/test-file.txt");
            
            //写入内容
            FileOutputStream out = new FileOutputStream(file, true);
            Scanner scanner = new Scanner(System.in);
            System.out.println("输入一句话： ");
            String str = scanner.next();
            System.out.println(str);
            out.write(str.getBytes());
            out.close();
        }
    }

使用idea的mave打包，步骤如下：

1.  项目结构 —> Artifacts : 点击" + " , JAR —> From module with dependencies

2.  选择Module, 选择Main class , 更改Directory for META-INFO/MANIFEST.MF路径： 选择该模块的根目录（和src同级）即可

3.  build

4.  查看jar包路径： copy path , 在控制台进行验证 \[ 输入: java -jar xx.jar \]
