Android Studio 3.0 Beta 1: Failed to resolve: com.android.support:multidex:1.0.2

Question

After migrating from Android Studio 3.0 (Canary 5) to Android Studio 3.0 (Beta 1), and moving to latest gradle , i.e. \'com.android.tools.build:gradle:3.0.0-beta1\'

Answer 1

If none of the above solutions are working then add mavenLocal() :

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

        mavenLocal()
        google()
    }
}

Answer 2

Move the google() item up to make sure it's before the jcenter().

repositories {
    jcenter()
    google()
}

Answer 3

Update all the gradle dependencies to latest version .. That’s it

Answer 4

if you are in China, Please use

allprojects {
    respositories {
        google()
    }
}

to instead

allprojects {
    respositories {
        maven {
            url 'https://maven.google.com'
        }
    }
}

don't ask me why, I don't want to tell you.... may be 'https://maven.google.com' was selected by GFW?

Answer 5

First you need to clean the project , and then rebuild it.

Build ----> Clean Project

Build ----> Rebuild Project

Answer 6

allprojects {
    repositories {
        google()
    }
}

worked for me instead of

allprojects {
    repositories {
        maven {
            url 'https://maven.google.com'
        }
    }
}
