Pom.xml的依赖自动生成

1.第一种用引入jar包的方法

以上是整个文件直接用idea打开即可

 import com.gugugu.maven.Poms;

 import java.io.IOException;

 /**
  * @author Administrator
  * @data 2020/2/22 - 13:50
  **/
 public class PomTest1 {
     public static void main(String[] args) throws IOException {
         Poms.getPomXMl("E:\\后端笔记\\常用工具\\数据校验\\lib");//jar包的位置
     }
 }

2.第二种:测试类解决

无需其他jar包,只需要测试类,

 import com.alibaba.fastjson.JSONObject;
 import org.dom4j.Element;
 import org.dom4j.dom.DOMElement;
 import org.jsoup.Jsoup;
 import org.junit.Test;

 import java.io.File;
 import java.io.FileInputStream;
 import java.io.FileNotFoundException;
 import java.io.IOException;
 import java.util.jar.JarInputStream;
 import java.util.jar.Manifest;
