Databinding unresolved after move to Gradle Kotlin DSL build scripts

Question

I had a working build, including databinding, but after migrating my Gradle build scripts to Kotlin DSL, I now have unresolved symbol errors for every use of import androidx.databinding.DataBindingUtil

My build.properties.kts contains the following:

plugins {
    id ("com.android.application")
    kotlin ("android")
    kotlin ("android.extensions")
    id ("de.mannodermaus.android-junit5")
}

android {
    lintOptions.isAbortOnError = false

    compileSdkVersion(28)
    defaultConfig {
        // ...
    }
    buildTypes {
        getByName("release") {
            isMinifyEnabled = false
            proguardFiles (getDefaultProguardFile("proguard-android-optimize.txt"), "proguard-rules.pro")
        }
    }
    dataBinding.isEnabled = true

    sourceSets {
        getByName("main").java.srcDir("src/main/kotlin")
        getByName("test").java.srcDir("src/test/kotlin")
    }
}

dependencies {
    // ...
}

Is dataBinding.isEnabled = true the right way to enable databinding, or do I need to do something else? (I know I could 'fix' this by going back to Groovy, but that feels a bit too much like giving up!)

Answer 1

This is how i enabled dataBinding in kotlin gradle file :

dataBinding {
    isEnabled = true
}

Voila ;)

hope this help someone

Answer 2

android {
    ...

    buildFeatures {
        dataBinding = true
    }
...

Answer 3

and for ViewBinding you can use :

viewBinding.isEnabled = true

Answer 4

EDIT: in 2019 databinding.isEnabled = true was the correct way to enable databinding.

Please now refer to the accepted solution for the right way to do this.

The problem turned out to be in my file naming. While migrating to Kotlin DSL, I had inadvertently renamed the gradle.properties file to gradle.properties.kts. After renaming the file I now have a fully functional build again!

Answer 5

You can use it like this:

android {

  buildFeatures {
         dataBinding = true

         // for view binding:
         // viewBinding = true
    }
}
