How to import Room Persistence Library to an Android project

It's possible to find the dependencies on the example codelab for the new architecture components.

Root :

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

For Room:

  implementation 'android.arch.persistence.room:runtime:1.0.0-alpha1'  annotationProcessor 'android.arch.persistence.room:compiler:1.0.0-alpha1'

For Lifecycle dependencies:

  implementation 'android.arch.lifecycle:extensions:1.0.0-alpha1'  annotationProcessor 'android.arch.lifecycle:compiler:1.0.0-alpha1'

Adding Rxjava2 objects as result for our queries:

  implementation 'android.arch.persistence.room:rxjava2:1.0.0-alpha1'

Test migrations:

  testImplementation'android.arch.persistence.room:testing:1.0.0-alpha1'

On your project root build.gradle you have to add Google's maven repository:

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

And then on the build.gradle of the Module you should add:

compile 'android.arch.persistence.room:runtime:1.0.0-alpha1'annotationProcessor 'android.arch.persistence.room:compiler:1.0.0-alpha1'compile 'android.arch.lifecycle:extensions:1.0.0-alpha1'annotationProcessor 'android.arch.lifecycle:compiler:1.0.0-alpha1'compile 'android.arch.persistence.room:rxjava2:1.0.0-alpha1'testCompile'android.arch.persistence.room:testing:1.0.0-alpha1'

Add this if you want to use RxJava2 Publisher and Flowable objects as a result of your queries

compile 'android.arch.persistence.room:rxjava2:1.0.0-alpha1'

And finally add also this dependency to test migrations

testCompile'android.arch.persistence.room:testing:1.0.0-alpha1'

Update: The libraries are still marked as Alpha1 so I guess the version number will be updated soon, maybe using 1.0.+ until there is a final version could be a good idea have been updated and as definded on the documentation you can use room 1.1.1 using this dependencies:

dependencies {   def room_version = "1.1.1"   implementation "android.arch.persistence.room:runtime:$room_version"   annotationProcessor "android.arch.persistence.room:compiler:$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   testImplementation "android.arch.persistence.room:testing:$room_version"}

open build.gradle(Project: projectName) and add this lines if it doesn't exist.

This enables access to google repository

allprojects {repositories {    jcenter()    google() }}

next open build.gradle(Module:app) and add this two lines to existing dependencies

For Java

def room_version = "1.1.0"implementation "android.arch.persistence.room:runtime:$room_version"annotationProcessor "android.arch.persistence.room:compiler:$room_version"

For Kotlin

paste this line outside of the dependencies or android scope at the top where kotlin plugins are applied

apply plugin: 'kotlin-kapt'

add this lines to dependencies

def room_version = "1.1.0"implementation "android.arch.persistence.room:runtime:$room_version"kapt "android.arch.persistence.room:compiler:$room_version"

to keep yourself updated with the recent dependencies version visit mvn repository for room

here you will find the latest version.
