Could not get resource for Android Architecture Components

Question

I applied to my project Android Architecture Components, by adding this lines to build.gradle:

// Android Architecture Lifecycle
compile "android.arch.lifecycle:runtime:1.0.0-alpha1"
compile "android.arch.lifecycle:extensions:1.0.0-alpha1"
annotationProcessor "android.arch.lifecycle:compiler:1.0.0-alpha1"

// Android Architecture Room
compile "android.arch.persistence.room:runtime:1.0.0-alpha1"
compile "android.arch.persistence.room:rxjava2:1.0.0-alpha1"
annotationProcessor "android.arch.persistence.room:compiler:1.0.0-alpha1"

It worked, but after updating Android Studio to Canary 3 version I'm still getting this error while compiling

Error:org.gradle.api.resources.ResourceException: Could not get resource 'https://jitpack.io/android/arch/lifecycle/runtime/1.0.0-alpha1/runtime-1.0.0-alpha1.pom'.

Error:org.gradle.api.UncheckedIOException: Could not HEAD 'https://jitpack.io/android/arch/lifecycle/runtime/1.0.0-alpha1/runtime-1.0.0-alpha1.pom'. Received status code 401 from server: Unauthorized

... other poms from library with the same error.

I tried restarting Android Studio, uninstalling app and of course clean-rebuild.

You need to add the new public Maven repo that Google is using to your build.gradle file.

For example, you could add it to the allprojects closure in the top-level build.gradle file:

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

Then, all of your modules (e.g., app/) will know to look there in addition to other places for the artifacts.

From your error message, it would appear that Android Studio is only looking in jitpack.io.
