gradle - Failed to resolve: com.google.android.material:material:1.0.0-alpha1

Question

So I'm following the official documentation to add the Material Components library to my project https://github.com/material-components/material-components-android/blob/master/docs/getting-started.md

But it throws me the following error "Failed to resolve: com.google.android.material:material:1.0.0-alpha1"

I've tried installing the repository and sync project that Android Studio suggest to no avail.

My project config

buildscript {

repositories {
    google()
    jcenter()
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.1.2'


    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
    classpath 'com.google.gms:google-services:3.2.1'
}
}

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


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

and the app config

apply plugin: 'com.android.application'

android {
compileSdkVersion 27
defaultConfig {
    applicationId "mlluell.eftremp"
    minSdkVersion 21
    targetSdkVersion 27
    versionCode 1
    versionName "1.0"
    testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"

        minifyEnabled false
        proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
    }
}

apply plugin: 'com.google.gms.google-services'

Answer 1

Instead of:

implementation 'com.google.android.material:material:1.1.0'

Use:

   implementation group: 'com.google.android.material', name: 'material', version: '1.1.0-alpha05'

And it works.
