gradle-5.1.1之大坑 -groovy-all:2.4.

最近在执行gradlew build命令时，总是出现如下bug，虽然不影响编译运行。但是作为一个严谨的人一定要查到原因

* What went wrong:
Execution failed for task ':app:lint'.

Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

百度了下，几个都是说设置lintOption，我试了下没卵用。还有说设置maven库的。都没用。不得不说百度真没用，好多问题都找不到好的解释，越查越乱。
最后当然是解决了，很明显吗，问题是获取这个groovy-all:2.4.15失败了，为什么失败呢？我猜是gradle - 5.1.1的bug。网站上能下载下来，但是构建的时候就是不行。那我就下载下来放目录下吧

放了后运行还是一样的错误，特么的。
我看了下gradle4.10.1的目录，咦？这个下面是有的。好吧，那我降下gradle版本吧，然后就行了。
