Android Studio 4.1 Canary：Firebase Crashlytics中断了android项目的编译

Question

[尝试从我正在研究的项目中删除即将弃用的Fabric Crashlytics SDK，以支持新的Firebase Crashlytics SDK。不幸的是我在以后编译时遇到麻烦。我不断收到以下异常：

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

这里是堆栈跟踪：

[使用新的Android Studio 4.1 Canary时似乎会出现此问题。我发现的唯一解决方法是回到使用Android Studio 4.0 Beta，别忘了还要将Android gradle插件版本调整为com.android.tools.build:gradle:4.0.0-beta02。

如果您正在玩Jetpack Compose，并且需要4.1，我想您必须禁用Crashlytics，直到在Android Studio或Crashlytics插件中修复此问题为止。
