Crashlytics could not find the resource file generated by Google Services. You may need to execute the :processGoogleServices Task

Question

I took back an old android project that hasn't been updated since more than 1 year and I tried to set it up with the current google librairies.

But I can't figure out how to solve one issue:

My application has 4 variants: devDebug, devRelease, prodDebug and prodRelease. Building the project is only working on *Debug ones. Release variants are producing this error:

Crashlytics could not find the resource file generated by Google Services. You may need to execute the :processGoogleServices Task.Please check your Firebase project configuration (https://firebase.google.com/docs/android/setup).

The application was already registred to firebase and the google-services.json file is already present (I also re-downloaded to be sure).

Some code inside the root gradle file:

dependencies {
        classpath 'com.android.tools.build:gradle:4.1.0'
        //apt : https://bitbucket.org/hvisser/android-apt
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'
        classpath 'com.google.gms:google-services:4.3.4'
        classpath 'com.google.firebase:firebase-crashlytics-gradle:2.4.1'
    }

allprojects {
    repositories {
        google()
        jcenter()
        maven {
            url 'https://jitpack.io'
        }
        maven {
            url 'https://maven.google.com/'
            name 'Google'
        }
    }
}

Some code of the app gradle file:

apply plugin: 'com.android.application'

        prod {

    }
}

    implementation 'com.google.firebase:firebase-crashlytics:17.3.0'

    // other libraries...
}

apply plugin: 'com.google.firebase.crashlytics'

configurations {
    cleanedAnnotations
    compile.exclude group: 'org.jetbrains', module: 'annotations'
}

Any hints are welcome.

Thanks.

The error is literally telling you what to do.

In terminal run:

./gradlew :app:processProdReleaseGoogleServices

or

./gradlew :app:processDevReleaseGoogleServices
