Can't build project with Android Studio 3.0 + DataBinding + Kotlin

Question

I have a huge project with databinding, kotlin, dagger. I spent a few days trying to build it using several stackoverflow's solutions and decided to ask it personally.

I assume some of third party libraries uses databinding because adding this line doesn't help.

kapt 'com.android.databinding:compiler:3.0.0' 

Android Studio says:

'androidProcessor' dependencies won't be recognized as kapt annotation processors. Please change the configuration name to 'kapt' for these artifacts: 'com.android.databinding:compiler:3.0.0'.

What I've tried and it didn't help:

   kapt {     generateStubs = true } 

in local.properties: kotlin.incremental=false

another SO solution didn't help:

kapt ('com.android.databinding:compiler:3.0.0'){         force = true     }

I just tried with similar build.gradle settings in a new and fresh kotlin project and it builds. Unfortunately I couldn't use all your libs and your exact setting but maybe it's just a matter of order. Here is my

build.gradle

apply plugin: 'com.android.application' apply plugin: 'kotlin-android' apply plugin: 'kotlin-kapt' apply plugin: 'kotlin-android-extensions'  kapt {     generateStubs = true }  android {

testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"          multiDexEnabled true     }     buildTypes {         release {             minifyEnabled false

At least I can verify with this test that

kapt 'com.android.databinding:compiler:3.0.0'  

is working for me. Maybe try it in a new project too and check if this works and then slowly apply your other libs one by one. Hope that gets you on track!
