Android Studio 4.1 Canary：Firebase Crashlytics 破坏了 android 项目编译

Question

UPDATE: This is fixed in Crashlytics Gradle plugin version 2.0.0-beta04 .

Been trying to remove the soon to be deprecated Fabric Crashlytics SDK from the project I'm working on in favour of the new Firebase Crashlytics SDK. Unfortunately I'm having trouble compiling afterwards. I keep getting the following exception:

Gradle sync failed: No such property: scope for class: com.android.build.gradle.internal.variant.ApplicationVariantData

Here's the stacktrace:

Answer 1

This is now fixed in Crashlytics Gradle plugin version 2.0.0-beta04.

So upgrade the project build.gradle file with:

...
dependencies {
        classpath "com.android.tools.build:gradle:$gradle_version"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath "com.google.firebase:firebase-crashlytics-gradle:2.0.0-beta04"
    }
...

Answer 2

This problem seems to occur when using the new Android Studio 4.1 Canary. The only workaround I've found is to go back to using the Android Studio 4.0 Beta, don't forget to also adjust the Android gradle plugin version to com.android.tools.build:gradle:4.0.0-beta02.

If you are playing around with Jetpack Compose and need 4.1 I guess you will have to disable Crashlytics until this is fixed either in Android Studio or the Crashlytics plugin.
