Android Studio 3.2.1 with new dataBinding import doesn't compile

How can I resolve this issue?
I installed a new Android Studio on my macOS and I would Like import dataBinding e to follow a tutorial about this technology. But when I import the dependencies and build the following error is shown.

databinding {
enabled = true
}
