* What went wrong:
Execution failed for task ':childgit:app:transformClassesWithProfilers-transformForDebug'.
> java.lang.NullPointerException (no error message)
* Try:
这个问题比较难搞，因为看不到任何错误，也不能通过清除无效缓存，或者重启电脑、或者重新编译、或者--info 或者--,或者--debug,或者--stackflow 或者--忘记了或者查看idea.log/或者查看项目目录错误文件或者修改gradle版本来辨别问题，不过又一个关键的信息，它出现的错误所处gradle任务为childgit:app:transformClassesWithProfilers
关键词profilers剖析，我最近做了一个操作就是分析oom,但是特么没分析出来只看到了内存暴涨和字符串飙升，也没有具体错误，后面发现日至控制台有一个红色的东西告诉我在哪一行才找到错误的。。。
所以根据这个任务名百度了一下发现也有人提问。但是我特么是犹豫了很久才选择百度的，因为着实没有具体错误信息啊，不知道百度应该如何百度了，就纠结了1个多小时啊，以后无解了，就谷歌提了问。然后躺了一下 然后决定百度看看

最后解决办法是取消勾选
