I'm trying some databinding with kotlin. but the BR.class is not generating any variables related to the data class. I have included the databinding library too. Any reason how this is happening?

mainBinding.setVariable(BR.temp, temp)

BR.temp gives unresolved reference

Do you have

kapt "com.android.databinding:compiler:$"

in your dependencies?

im currently using

kapt 'com.android.databinding:compiler:3.0.1'

Do you have data binding enabled in all your modules?

The main reason for error was incorrect setters in the data class which prevented two way data binding and hence the build was not completed.
