Gradle project sync failing after Google announced the new sdk versioning system

Question

I am getting the following error:

Cannot change dependencies of configuration ':app:api' after it has been included in dependency resolution. 

Updated: I am able to build using com.google.gms:google-services:3.3.0 when data binding is disabled, but this is not a solution for someone that requires data binding to be enabled.

After Google announced the new sdk versioning system (link), I did the following steps:

1. I updated the gradle files as directed to include the gms and firebase version numbers separately. Updated the apply plugin line, updated the classpath. I am still getting the error and dont know the reason.

2. Below are relevant gradle files:

build.gradle (main):

buildscript {     repositories {         google()         jcenter()         maven { url 'https://dl.bintray.com/rvalerio/maven' }         maven { url 'https://maven.fabric.io/public' }     }     dependencies {         classpath 'com.android.tools.build:gradle:3.1.2'         classpath 'com.google.gms:google-services:3.3.0'         classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'         classpath 'io.realm:realm-gradle-plugin:4.3.3'         classpath 'io.fabric.tools:gradle:1.25.1'         // NOTE: Do not place your application dependencies here; they belong         // in the individual module build.gradle files     } }  allprojects {     repositories {         google()         jcenter()         maven { url 'https://jitpack.io' }         maven { url 'https://maven.google.com' }     } } 

build.gradle (Module:app)

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

Firebase dependencies:

//Firebase Dependencies implementation "com.google.firebase:firebase-messaging:15.0.2" implementation "com.google.firebase:firebase-core:15.0.2" implementation "com.google.firebase:firebase-config:15.0.2" implementation('com.crashlytics.sdk.android:crashlytics:2.9.1@aar') {     transitive = true } 

GMS and other dependencies

implementation "com.android.support:recyclerview-v7:27.1.1" implementation "com.android.support:support-v4:27.1.1" implementation "com.android.support:cardview-v7:27.1.1" implementation "com.android.support:design:27.1.1" implementation "com.android.support:support-v13:27.1.1" implementation "com.android.support.constraint:constraint-layout:1.1.0" implementation "com.google.android.gms:play-services-location:15.0.1" implementation "com.google.android.gms:play-services-vision:15.0.1" implementation "com.google.android.gms:play-services-auth:15.0.1" implementation "com.google.android.gms:play-services-maps:15.0.1" 

3. I have pasted the error log on pastebin from android studio 3.1.2 here.

Any help is appreciated!

Answer 1

managed to build against Play Services & Firebase 15.0.0 with data-binding enabled ...my dependencies now look about alike this and it builds again, without any Cannot change dependencies of configuration complaints:

buildscript {      dependencies {          classpath "com.android.tools.build:gradle:3.1.2"          // do not update, because 3.3.1 appears broken         // classpath "com.google.gms:google-services:3.2.1"          // meanwhile, there is version 4.0.2 available         classpath "com.google.gms:google-services:4.0.2"     } } 

one has to reference all the libraries individually. just referencing com.google.android.gms:play‐services and/or com.google.firebase:firebase-core does not work anymore since 15.0.0.

android {      dependencies {          // Play Services 15.0.0         implementation "com.google.android.gms:play-services-base:15.0.1"         implementation "com.google.android.gms:play-services-auth:15.0.1"         implementation "com.google.android.gms:play-services-identity:15.0.1"          // Firebase 15.0.0         implementation "com.google.firebase:firebase-core:15.0.2"         implementation "com.google.firebase:firebase-database:15.0.1"         implementation "com.google.firebase:firebase-firestore:16.0.0"         implementation "com.google.firebase:firebase-storage:15.0.2"         implementation "com.google.firebase:firebase-crash:15.0.2"         implementation "com.google.firebase:firebase-auth:15.1.0"         implementation "com.google.firebase:firebase-messaging:15.0.2"         implementation "com.google.firebase:firebase-config:15.0.2"         implementation "com.google.firebase:firebase-invites:15.0.1"         implementation "com.google.firebase:firebase-ads:15.0.1"         implementation "com.google.firebase:firebase-appindexing:15.0.1"         implementation "com.google.firebase:firebase-perf:15.2.0"         implementation "com.google.firebase:firebase-functions:15.0.0"     } }  apply plugin: 'com.google.gms.google-services' 

also had to edit the Manifest.xml to fix the support library:

<application>      <meta-data         android:name="android.support.VERSION"         android:value="27.1.1"         tools:replace="android:value"/>  </application
