Error:Failed to resolve: runtime Open File

here is build.gradle(Project) file:

   // Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

    repositories {
        google()
        jcenter()

    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.1'
        classpath 'com.google.gms:google-services:3.2.0'


        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com" // Google's Maven repository
        }
    }
}

Answer 1

Based on the answer in Android Studio 3.1.2 : Failed to resolve: runtime, try changing the order of imports in build.gradle project file as

allprojects {
    repositories {
        google()
        maven {
            url "https://maven.google.com" // Google's Maven repository
        }
        jcenter()

    }
}

This worked for me.

Answer 2

allprojects {
    repositories {
        google()
        maven {
            url "https://maven.google.com" // Google's Maven repository
        }
        jcenter()

    }
}

You must place google() as the 1st line. Reminder First line. I hope it will help you.

Answer 3

This is very weird and took me almost 4-5 hours to fix. But, it turns out you need to put google() at the top and jcenter() at the bottom of repositories in build files for all modules. Maven can go in between and it'll be fixed.

Answer 4

This worked for me

repositories {
    google()`Goolge repo`
    jcenter()
    maven {
        url 'https://maven.google.com/ `Google maven repo`
        name 'Google'
    }

}
