Data-binding went stuck after Android Studio 3.1 Canary 6+ (updated 12.21.2018)

I have updated all in Canary 6 of AS 3.1, see here, including data-binding to v2.

Now, something will stuck in wrong, that a lot standard "android:xxxx" cannot be bound, also some customized bind-adapters either.

See here

Cannot find the setter for attribute 'android:onClick' with parameter type lambda on android.widget.TextView.

Cannot find the setter for attribute 'android:onViewAttachedToWindow' with parameter type lambda on android.widget.ScrollView.
