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

Please follow this as same (sequentially) in build.gradle (project: projectName) and issue will be gone

buildscript {

repositories { // keep same this order
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.1.3'

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

allprojects { // keep same this order
    repositories {
        google()
        jcenter()
    }
}

task clean(type: Delete) {
delete rootProject.buildDir
}
