Can't find Android Support Repository in SDK Manager

Question

Under Tools, select Android SDK Tools and Android SDK Platform-tools and update.

Once updated, restart your SDK Manager. Android Support Repository will now be available under Extras.

As of today, the android support libraries are now available through Google's Maven repository. reference: https://developer.android.com/topic/libraries/support-library/setup.html

by adding maven section in repositories tag in build.gradle of project.

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

kehers answer worked before but now that library has been renamed to:

Local Maven repository for Support Libraries and its also under Extras.

I also faced the same problem. You should update your Android SDK Tools and Android SDK Platform-tools. That will bring the option of Support Repository.
