追踪Maven中央仓库中某个包的某个类的变化历史,用于在开发Agent类产品的时候辅助提升开发效率与质量,比如我要通过ASM Hook住dubbo的某个类Foo,但是我不知道这个Foo在所有的版本中都发生了哪些变化,那么我的代码可能只对其中某些版本有效,对另外一些版本就可能会crash,但是所有的版本太多了又不方便全部测试那会是一个很大的工作量,那么使用这个工具就能够追踪类Foo将类Foo发生变化的版本和对应的Class字节码找出来,只需要测试发生了变化的这些类和版本就可以了,基本上能够将工作量缩小一个数量级(属于弱辅助性工具效果有限,手头没更好的就凑活用...)。

所有命令:
主要是track命令:
Usage:
class-version-tracker.exe track -g org.apache.dubbo -a dubbo -c org.apache.dubbo.rpc.protocol.DelegateExporterMap -o output class-version-tracker.exe track -g org.apache.dubbo -a dubbo -c org.apache.dubbo.rpc.protocol.AbstractProtocol -o output class-version-tracker.exe track -g org.apache.dubbo -a dubbo -c org.apache.dubbo.rpc.protocol.dubbo.DubboProtocol -o output class-version-tracker.exe track -g org.apache.dubbo -a dubbo -c org.apache.dubbo.common.extension.ExtensionLoader -o output class-version-tracker.exe track -g com.alibaba -a dubbo -c com.alibaba.dubbo.rpc.protocol.AbstractProtocol -o output class-version-tracker.exe track -g com.alibaba -a dubbo -c com.alibaba.dubbo.common.extension.ExtensionLoader -o output class-version-tracker.exe track -g com.alibaba -a dubbo -c com.alibaba.dubbo.rpc.protocol.dubbo.DubboProtocol -o output
输出结果:
会对给定的类的所有版本按照md5分组,对于每个分组,会使用当前组下的最小的版本作为文件名把类的字节码写到磁盘上,所以输出的这些带版本的class大体上是有序的。
report.json是对结果的一个概况:

支持指定是使用本地mvn配置的镜像仓库还是直接连中央仓库,因为某些镜像仓库有点坑(某里),会有那种版本空洞,冷不丁给你来一下
-
支持中央仓库之外的仓库
