Update AS/Kotlin now get data binding build error

I updated to AS 2.3 today after updating to Kt 1.1 recently. Now I get errors on DataBindingInfo.java. Any tips? Also, just realized, build tools were updated to 25.

Hi I have similar error before, add this line to your build.gradle
apply plugin: ‘kotlin-kapt’
it works for me

Ok thanks.
BTW I also needed to do ‘rebuild project’ before error went away
