maven依赖查找小工具

## 0.背景 ##

对于项目中引入的依赖，我们可以使用依赖树去分析，查找某个依赖是哪里引入的，但是若是给一份依赖的名单，如何能快速查找那些依赖不在名单呢？一个一个去搜索肯定效率低下。  
尤其产品安全较为严格的项目，每个引入的依赖都是严格限制的，开源软件使用需要申请并分析安全漏洞，版本升级需要重新申请，那么发布的时候如何知道我所使用的就是申请的那些呢？

## 1.解决办法 ##

首先使用命令将依赖打印到文件中

mvn dependency:tree > /tmp/tree.txt

例如一个这样的依赖树

我的匹配名单为

    spring-boot-starter-json-2.2.5.RELEASE.jar
    spring-boot-starter-web-2.2.5.RELEASE.jar

    spring-boot-starter-logging-2.2.5.RELEASE.jar
    logback-core-1.2.4.jar

凡是不在名单中的或者版本号不正确的都打印引入完整路径  
定义树节点

import lombok.Data;
    
    @Data
    public class TreeNode { 
        private String groupId;
        private String artifactId;
        private String version;
        private String scope;
        private TreeNode parent;
        private int length;
    }

中间使用一个map保存父节点，每次按照长度作为key put到map中，则同等长度会覆盖，按照length-1去找找到的一定是直接父级。
