I'm getting an Access denied error to your build log , and I didn't use it, but I'll try to answer you.

As announced here :

The Android Gradle Plugin 3.0.0-alpha3 was also released through maven.google.com.

You can try to fix it by adding Google's Maven Repository here like this :

buildscript {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-alpha3'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

Make sure that the repositories section includes a maven section with the " https://maven.google.com " endpoint. For example:

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

As commented here , this version doesn't exist in Bintray JCenter:

com.android.tools.build.gradle latest version is 2.5.0-alpha-preview-02, there is no 3.0.0-alpha3

Also be sure to update build tools to the latest version as suggested in this related question :

Update your build tools from SDK manager

I add links to samples using the new sdkmanager command line here .

I would need a sample project reproducing the issue to check my suggestions.
