使用约束布局2.0.0-beta2时，已经定义了属性失败，构建失败

Question

[当我使用com.android.support.constraint:constraint-layout:2.0.0-beta2我收到以下构建错误。

如果使用com.android.support.constraint:constraint-layout:2.0.0-alpha2，则不会出现任何错误。

为什么会出现这些错误？如何摆脱这个？

[我看到app：alpha在https://androidstudio.googleblog.com/2019/05/constraintlayout-200-beta-1.html中重命名为android：alpha
