Android Studio 3.0 - Unable to find method 'com.android.build.gradle.internal.variant.BaseVariantData.getOutputs()Ljava/util/List'

Question

Trying to start a new Kotlin project with Android Studio 3.0 Canary 1 displays this error. Full trace:

Error:Unable to find method 'com.android.build.gradle.internal.variant.BaseVariantData.getOutputs()Ljava/util/List;'. Possible causes for this unexpected error include:

• Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.) Re-download dependencies and sync project (requires network)
• The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem. Stop Gradle build processes (requires restart)
• Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.

In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.

I've tried the first two options and the third-party plugins are left as default.

build.gradle

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    ext.kotlin_version = '1.1.2-3'
    repositories {
        maven { url 'https://maven.google.com' }
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-alpha1'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        maven { url 'https://maven.google.com' }
        mavenCentral()
    }
}

task clean(type: Delete) {
    delete rootProject.buildDir
}

I haven't touched any of these values myself, they're left as default. Creating a non-Kotlin new project does not have this problem.

Answer 1

In my build.gradle changing

ext.kotlin_version = '1.1.2-3'

to

ext.kotlin_version = '1.1.2-4'

fixed this.

You can find the most recent version here.

Answer 2

It worked for me

Using the 8.4.0 version

 classpath 'com.jakewharton:butterknife-gradle-plugin:8.4.0'  

Answer 3

For Java

Just remove

classpath 'me.tatarka:gradle-retrolambda:3.7.0'

downgrade butterknifeversion to 8.4.0

classpath 'com.jakewharton:butterknife-gradle-plugin:8.4.0'

Don't forget to remove

apply plugin: 'me.tatarka.retrolambda'

from app level build gradle.
