Android Studio 3 + Gradle 4.0 + shrinkResources + libraryProject = Unable to find a matching configuration in project

I've problems to migrate my project to the newest Gradle 4.0 + Android Studio 3 version, which gives me all kind of errors. Little by little I managed to sort them all out except this one.

    Could not resolve all dependencies for configuration ':app:forGoogleCoverageRuntimeClasspath'.

In order to nail down the problem:

I've created a minimum app project from Android Studios project assistant
added an empty library module which I then add to my app dependencies.
added one flavorDimensions and 2 productFlavors
added 3 build types and let one build type inherit from another
let the inherited build type enable shrinkResources

The last step produces the mentioned error, which is similar to this question: Gradle 4.0 Unable to find a matching configuration

Has anybody an idea what's the matter here or an solution to this problem? I'll file a bug report too.

My complete gradle file:

apply plugin: 'com.android.application'

apply plugin: 'kotlin-android'

android {
    compileSdkVersion 25
    buildToolsVersion "25.0.2"
    defaultConfig {
        applicationId "gradletest.test"
        minSdkVersion 16
        targetSdkVersion 25
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }

    flavorDimensions "store"

    productFlavors {
        forAmazon {
            dimension "store"
        }

        forGoogle {
            dimension "store"
        }
    }

    buildTypes {

        debug {
            debuggable true
            minifyEnabled false
        }

        release {
            minifyEnabled true
            debuggable false
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }

        coverage.initWith(buildTypes.debug)
        coverage {
            testCoverageEnabled true
            minifyEnabled true
            shrinkResources true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }


}

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile "org.jetbrains.kotlin:kotlin-stdlib-jre7:$kotlin_version"
    compile 'com.android.support:appcompat-v7:25.3.1'
    testCompile 'junit:junit:4.12'
    compile 'com.android.support.constraint:constraint-layout:1.0.2'

    implementation project(':mylibrary')
}

Solution

Possible workaround is create in all modules missing buildTypes, but it's crazy messing code when Google planed create a sollution for it. More info in: https://issuetracker.google.com/issues/62170415 as me (but deleted by moderator) and you mention.

But there is second (same but much cleaner) solution: add this to your top project build.gradle

subprojects {
    afterEvaluate {project ->
        if (project.hasProperty("android")) {
            android {
                buildTypes {
                    YOUR_MISSING_BUILD_TYPES {
                       BUILD_TYPE_PARAMS_OR_EMPTY
                    }
                }
            }
        }
    }
}

EDIT: 2017-07-12

It's finally fixed in classpath 'com.android.tools.build:gradle:3.0.0-alpha6'. You can use new DSL: https://issuetracker.google.com/issues/62241369

android {
  buildTypeMatching 'staging', 'debug'
  productFlavorMatching 'color', 'blue', 'cyan'
}

Don't forgot to remove above workaround before build project!

EDIT: 2017-07-18

There is official documentation: https://issuetracker.google.com/issues/62241369

To resolve this error, you need to specify which build type from "mylibrary" the Android plugin should match to the app's "staging" build type. You can do this with the buildTypeMatching property in the app's build.gradle file, as shown below:

// Add the following to the consumer's build.gradle file.
android {
    ...
    // Tells the Android plugin to use a library's 'debug' build type
    // when a 'staging' build type is not available. You can include
    // additional build types, and the plugin matches 'staging' to the
    // first build type it finds from the one's you specify. That is,
    // if 'mylibrary' doesn't include a 'debug' build type either, the
    // plugin matches 'staging' with the producer's 'release' build type.
    buildTypeMatching 'staging', 'debug', 'release'
}

EDIT: 2017-09-06

buildTypeMatching has been removed from AS beta 4.
now use matchingFallbacks.
