Kotlin: Android Studio 3.0 – Unable to find method ‘com.android.build.gradle.internal.variant.BaseVariantData.getOutputs()Ljava/util/List’

Question or issue of Kotlin Programming:

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

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

gradle-wrapper.properties

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.

How to solve this issue?

Solution no. 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.

Solution no. 2:

It worked for me

Using the 8.4.0 version

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

Solution no. 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.

Solution no. 4:

This is a known issue in Android Studio Preview 3.0:

If you see this error, it’s possible you have a pre-existing version of the Kotlin plugin that is incompatible with the new Android Plugin for Gradle that’s in Android Studio 3.0. The solution is to delete the old Kotlin plugin.
Open your project-level build.gradle file and locate ext.kotlin_version. It should be 1.1.2-4 (or higher). If it shows an older version, you need to delete the old Kotlin plugin so it does not obstruct the version included with Android Studio 3.0.
On Windows, it should be located at
C:\Users\user_name\AndroidStudio_version\config\plugins\Kotlin\
On Mac, look in
~/Library/Application\ Support/AndroidStudio_version/Kotlin/

Solution no. 5:

In my case, the issue was caused because we were applying butterknife-gradle-plugin. Upgrading to 8.8.1 didn’t fix the issue, but removing it certainly did.

The build.gradle belongs to the application, so I don’t even know why we are using that plugin (I’m new to the project)

Solution no. 6:

Update your kotlin version to the latest:

ext.kotlin_version = '1.1.2-4' //currently it's the latest version

Then you may face some more errors, so before syncing again, make sure that your buildToolsVersion is “26.0.2” or higher.

Hope this helps!
