Jar Finder

一、这是什么？解决了什么问题？

• 用于把Jar包转换为Maven的GAV坐标来精简项目依赖

比如是通过逆向的方式分析出一个闭源的Java应用发行版的API来使用，一般这种情况下依赖的Jar包会分为两类，其中一类是此应用本身的依赖包，比如这个应用它依赖到了Apache的一些包，通常会以一堆Jar包的形式放在应用安装目录下一个名为lib的文件夹内，这个时候我们可以选择把这个lib文件夹囫囵个儿拷贝到我们自己的项目中然后把整个lib文件夹添加到依赖，虽然也能够跑起来，但是这有一些弊端，为了避免依赖丢失，这些Jar包我们得提交到仓库，通常情况下会有几百兆甚至上G，这要了老命了，或者更好的方式是既然我们知道这些Jar包都在Maven中央仓库中存在，那么我们直接把他们加入到pom.xml中即可，让Maven构建的时候从中央仓库中下载，但是问题来了，我们如何快速的将这些jar包转为Maven的dependency呢？这个工具就是干这个用的。

• 找出一堆Jar包中哪些是在Maven中央仓库上的，哪些是在自定义的包

比如我们要逆向分析一个Java应用，找到了与这个Java应用相关的一堆Jar包，但是这些Jar包中哪些是有分析价值的呢？公共的依赖包对于逆向分析的帮助不大（我们看了半天才发现是一个公共包岂不是日了狗），应用自己的Jar包对我们的帮助会比较大，而通常情况下应用自己的Jar包是不会托管到Maven仓库中的（当然也有一些例外），我们可以借助此工具大致把有分析价值的包区分出来。

二、下载安装

release页面下载或者自己go get仓库编译

三、使用示例

查找给定的jar包在Maven仓库中的GAV：

jar-finder.exe find --jar ./test_data/commons-lang3-3.8.jar

结果：

查找给定文件夹下的jar包在仓库中的GAV：

jar-finder.exe find -d ./test_data

在查询的时候并将结果输出为pom.xml的形式：

jar-finder.exe find -d ./test_data --pom pom.xml

pom.xml的数据样例：

<?xml version="1.0" encoding="UTF-8"?>
