踩坑记录

1第一次运行，会耗时，因为要下载robo库

但是这个过程漫长到，这一定是一个bug

but no solution yet，just wait，第一次的时间是真的长。

可以参照里面对我的回复，手工先下载jar包。

之后就非常快了

2.配置过时

网上的一些资料配置，完全就是过时的

3.AndroidX的兼容

The given artifact contains a string literal with a package reference 'android.support.v4.content' that cannot be safely rewritten. Libraries using reflection such as annotation processors need to be updated manually to add support for androidx.

不是butterKnife的问题,不知道哪个库出问题了。

android.jetifier.blacklist=shadows

works for me

4.该框架不能支持so的测试

涉及到一个动态库的编译，但是我们这里报错的全是第三方库，尤其类似地图so

都会see 1171 这个单
