以上是整个文件直接用idea打开即可

import com.gugugu.maven.Poms;

import java.io.IOException;

/**

**/
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;
