Android buildTypes vs. productFlavors error

Question

Decided to switch to from Android gradle plugin 3.5.x to gradle plugin 4.10 with Gradle 6.5 and stuck with mistake.

Here's my build.gradle

defaultConfig {

    applicationId "com.example.myapp
    targetSdkVersion targetSdkVersionVar
    multiDexEnabled true
}

flavorDimensions "version"

productFlavors {
    kitkat {
        sourceSets { "src/android/kitkat" }
        dimension "version"
        minSdkVersion minSdkKitkat
        targetSdkVersion targetSdkKitkat
        versionNameSuffix "-kitkat"
    }
    nougat {
        sourceSets { "src/android/nougat" }
        dimension "version"
        minSdkVersion minSdkNougat
        targetSdkVersion targetSdkVersionVar
        versionNameSuffix "-nougat"
    }
}

Before that, when I was using gradle-tools v 3.x - it was working really fine.

Any thoughts, ideas, hints, clues?

Answer 1

It seems that issue you have is that your main project uses your library that has flavor dimensions, and your app doesn't know which one to use. You should Use missingDimensionStrategy in the defaultConfig block to specify the default flavor. For example :

missingDimensionStrategy 'dimension', 'flavor1', 'flavor2'

Please check this link for more details.

Answer 2

Following to @Chriki's comment tried to formulate minimal reproducible question and suddenly found a solution. Magic was in statement:

android {
    ...
    dynamicFeatures = [":app"]
}

Whenever I have commented this line, everything works.

P.S. Here are should be hateness radiation to gradle logs/debug messages, actually absense of those logging/messaging. In the end I spent nearly a week trying to find a solution and in the end found by accident.

If @Chriki would post answer I will reward bounty to him.
