Failed to resolve: android.arch.lifecycle:extensions:1.0.0-alpha1 android studio 3.0

I am building a project in android studio 3.0 with android plugin 'com.android.tools.build:gradle:3.0.0-alpha1' and gradle version gradle-4.0-milestone-1-all.zip.

Used maven repo as well:

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

Also, Using android Room persistence and lifecycle in my project. Already declared below dependencies in my app gradle file:

compile "android.arch.lifecycle:extensions:1.0.0-alpha1"
compile "android.arch.persistence.room:runtime:1.0.0-alpha1"
annotationProcessor "android.arch.lifecycle:compiler:1.0.0-alpha1"
annotationProcessor "android.arch.persistence.room:compiler:1.0.0-alpha1"

When Sync and build the project it's showing below error:

Failed to resolve: android.arch.lifecycle:extensions:1.0.0-alpha1

Am I missing something or any other solution for this issue.

    annotationProcessor "android.arch.persistence.room:compiler:$room_version" // use kapt for Kotlin

    // optional - RxJava support for Room
    implementation "android.arch.persistence.room:rxjava2:$room_version"

    // optional - Guava support for Room, including Optional and ListenableFuture
    implementation "android.arch.persistence.room:guava:$room_version"

    // Test helpers

You require latest gradle version 'com.android.tools.build:gradle:3.0.0-alpha2' and Studio Version 3.0+ to use Room

Add in app/gradle file

compile "android.arch.lifecycle:extensions:1.0.0-alpha4"
compile "android.arch.persistence.room:runtime:1.0.0-alpha4"
annotationProcessor "android.arch.lifecycle:compiler:1.0.0-alpha4"
annotationProcessor "android.arch.persistence.room:compiler:1.0.0-alpha4"

add maven to project based gradle

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

it will compile easily

you can change "https://maven.google.com" to "https://dl.google.com/dl/android/maven2/" to solve the problem.

I have fixed the issue by updating my app build.gradle file like below:

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-alpha2'
        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

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

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

Actually had to remove the maven repository from buildscript repositories and added to allprojects repositories as shown above. Also you can keep the maven repository at both places but must include in allprojects repositories to fix the issue.
