flavorDimensions gradle error - Android Studio 3.0 Canary 1

I would like to upgrade my project to Android Studio 3.0 Canary 1 and the gradle:3.0.0-alpha1 plugin, however I have a problem with the correct definition of flavors for included projects.

I followed the official migration guide from Google: https://developer.android.com/studio/preview/features/new-android-plugin-migration.html

In my main app build.gradle I defined the "myflavor" flavorDimensions, as recommended by the migration guide:

android {
    flavorDimensions "myflavor"

    productFlavors {
        dev {
            dimension "myflavor"
            minSdkVersion 21
        }
        prod {
            dimension "myflavor"
            minSdkVersion 16
        }
    }

    buildTypes {
        debug {
            signingConfig signingConfigs.debug
        }

        release {
            debuggable false

            signingConfig signingConfigs.release

            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
}

dependencies {
    compile project(':util')
}

In my included :util module (producer), I tried to include it withouth a definition of flavorDimensions, productFlavors and buildTypes. I get the following gradle error:

Error:Could not resolve all dependencies for configuration ':app:prodDebugCompileClasspath'.
  Cannot choose between the following configurations on project :util:
    - debugApiElements
    - releaseApiElements
  All of them match the consumer attributes:

        - Found com.android.build.gradle.internal.dependency.AndroidTypeAttr 'AndroidTypeAttr{name=Aar}' but wasn't required.

        - Required myflavor 'ProductFlavorAttr{name=prod}' but no value provided.

        - Found com.android.build.gradle.internal.dependency.AndroidTypeAttr 'AndroidTypeAttr{name=Aar}' but wasn't required.

        - Found com.android.build.gradle.internal.dependency.VariantAttr 'VariantAttr{name=release}' but wasn't required.
        - Required myflavor 'ProductFlavorAttr{name=prod}' but no value provided.
        - Required org.gradle.api.attributes.Usage 'for compile' and found compatible value 'for compile'.

When defining the same flavorDimensions, productFlavors and buildTypes in :util as in the main :app, I get the following error message:

Error:Could not resolve all dependencies for configuration ':app:prodDebugCompileClasspath'.

What is the correct way to include my :util lib without getting the error?

From https://issuetracker.google.com/issues/65867056:

You should have only one buildScript block in the root build.gradle. If you are using Composite builds, this is not currently supported by our plugin due to limitations in Gradle.

EDIT: I guess this now works for latest versions of gradle

I got around this by using gradle 4.3 (with Android Studio 3.0)

To use it with Android Studio 3.0:

  1. Download the binary here: https://gradle.org/releases/
  2. Configure local gradle binary in Android Studio, under preferences...

enter image description here

  1. Then in your gradle file replace compile with either implementation or api depending on your requirements.

ALSO: make sure that your external modules (i.e util) have the same flavors as your App or you will get the error outlined in here: Gradle 4.0 Unable to find a matching configuration
