ClassNotFoundException: Didn't find class “android.databinding.DataBinderMapper”

Question

I am using android\'s data binding library for views in a library project

i have added the following line in my root gradle file

classpath \'         


        

Answer 1

I had the same problem, but I solved it removing

classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'

from the global build.gradle and removing

apply plugin: 'android-apt'

from the local build.gradle, then it worked like a charm.

It seems it was a mixed problem with Butterknife too. Pretty weird.
