DSL element ‘android.dataBinding.enabled’ is obsolete and has been replaced with ‘android.buildFeatures.dataBinding’.
It will be removed in version 5.0 of the Android Gradle plugin.

实际上就是换一种写法。

原来：

dataBinding {
        enabled true
    }

现在：

buildFeatures{
        dataBinding = true
        // for view binding :
        // viewBinding = true
    }
