Android Studio 3.1.2 : Failed to resolve: runtime

Question

I have recently updated my Android Studio to 3.1.2 . After the update I tried opening the existing project and was shown multiple gradle errors while compiling the project.

Answer 1

Add maven { url 'https://maven.google.com' } as first entry in allprojects/repositories in top level build.gradle

like this:

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