maven项目中pom.xml快速生成

项目引用的jar包数了一下将近100个，直接引用其他项目的pom文件自然也不适合。所以有了下面的代码，把使用到的jar包放在文件夹中，运行一下，自动生成。

1.  
   import java.io.File;
2.  
   import java.io.FileInputStream;
3.  
   import java.io.FileNotFoundException;

14.  
    File dir = new File("F:/lib"); //需生成pom.xml 文件的 lib路径
15.

    e.printStackTrace();

    }

    }

生成之后可能会引用一些依赖，不想要这些依赖的话可以在pom.xml加上这些就不引用依赖了

 <exclusions>
            <exclusion>
                <groupId>*</groupId>
                <artifactId>*</artifactId>
            </exclusion>
     </exclusions>
