git bisect实战

这是一个用来重现Maven的MNG-6700的实战项目。将本项目clone到本地，然后分别使用Maven 3.6.0和3.6.1运行mvn compile，你会发现：

Maven 3.6.0

[INFO] ------------------------------------------------------------------------
[INFO] BUILD SUCCESS

这意味着，在Maven的3.6.0和3.6.1之间有某个提交引入了一个bug，导致了MNG-6700。请运用git bisect大法，找到引入bug的commit和责任人。
