When opening a project in Android Studio, an error occurs, what should I do?

Question

Java

In general, I can not understand what's the matter, what he requires of me. The project is written in Java

This is what the compiler says: ERROR: No signature of method: com.crashlytics.tools.gradle.CrashlyticsPlugin.findObfuscationTransformTask() is applicable for argument types: (java.lang.String) values: [Debug]

Answer 1

The project and IDE have incompatible versions of the Crashlytics plugin.
