maven排查冲突jar包

1. 问题描述

使用maven可以非常方便的管理我们项目的各种依赖，但是也存在着一些问题。当我们在pom.xml文件中引入新的jar包，那么该jar包依赖的其它jar包也会自动被下载。如果这些自动下载的jar包和项目中已存在的jar包版本不一致，那么就会造成jar包版本的冲突。

2. 解决方法

我们可以使用mvn命令来排查项目中存在版本冲突的jar包。

首先，在命令行跳转到当前项目路径（如果使用Idea等工具，可以直接在终端Terminal中运行mvn命令），为了便于查找我们可以把依赖关系写入一个临时文本文件tree.txt。
```
mvn dependency:tree -Dverbose > tree.txt
```

然后，打开生成的tree.txt文件，全局搜索”conflict”关键字，即可找到版本冲突的jar包。
