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" } buildTypes {     release {         minifyEnabled false         proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'     } } }  dependencies { implementation fileTree(dir: 'libs', include: ['*.jar']) implementation 'com.android.support:appcompat-v7:27.1.1' implementation 'com.android.support:cardview-v7:27.1.1' implementation 'com.android.support:customtabs:27.1.1' implementation 'com.android.support.constraint:constraint-layout:1.1.0' implementation 'com.google.firebase:firebase-auth:15.1.0' implementation 'com.google.android.gms:play-services-auth:15.0.1' implementation 'com.google.firebase:firebase-database:15.0.1' implementation 'com.google.firebase:firebase-storage:15.0.2' implementation 'com.android.support:design:27.1.1' implementation 'com.android.support:appcompat-v7:27.1.1' implementation 'com.google.android.material:material:1.0.0-alpha1'  //imatges recyclerview implementation 'com.android.support:recyclerview-v7:27.1.1' implementation 'com.github.bumptech.glide:glide:4.6.1' annotationProcessor 'com.github.bumptech.glide:compiler:4.6.1'  // FirebaseUI for Firebase Realtime Database implementation 'com.firebaseui:firebase-ui-database:3.3.0'  // FirebaseUI for Firebase Auth implementation 'com.firebaseui:firebase-ui-auth:3.3.0'  // FirebaseUI for Cloud Storage implementation 'com.firebaseui:firebase-ui-storage:3.3.0'   testImplementation 'junit:junit:4.12' androidTestImplementation 'com.android.support.test:runner:1.0.2' androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2' }  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.

Answer 2

Thought I'd share what fixed this for me now that I|O has started.

I had about the same initial setup as you. To get it working I had to change the following:

• compileSdkVersion to 'android-P'
• Support Libraries to '28.0.0-alpha1'
• include api 'com.android.support:design:28.0.0-alpha1' in the dependencies block.
• SDK Platform update - Android P Preview (latest)
• targetSdkVersion 'P'

I then did the ritualistic 'Invalidate Caches / Restart' and rebuilt the project for good measure.
