Gradle project sync failing after Google announced

问题:

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!

回答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

The issue with data binding and the 3.3.0 version of the google-services plugin has been reported here: https://issuetracker.google.com/issues/79122163

As of today, the bug is in the "assigned" state.

回答3:

UPDATE I could compile also with

dataBinding.enabled false

In android configuration and version 3.3.0

ORIGINAL

Same problem here with google-services:3.3.0, which is the last version, but according to docs version 3.2.1 should be used. I've been able to compile with the following

 ext {
    kotlin_version = '1.2.41'
    firebaseCore = '15.0.2'
    authentication = '15.1.0'
    cloudFirestore = '16.0.0'
    cloudStorage = '15.0.2'
    crashlitics = '2.9.1'
    googleServices = '15.0.0'
    supportLibrary = '27.1.1'
    facebookSdkVersion = '4.31.0'
    twitterSdkVersion = '3.1.1'
    firebaseUI = '3.3.1'
}
 dependencies {

    classpath 'com.android.tools.build:gradle:3.2.0-alpha12'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"

    classpath 'com.google.gms:google-services:3.2.1'
}

回答4:

This issue seems to have been resolved by using the new google-services release (4.0.1 as of today). Below is the relevant versions that will resolve the stated issue:

In your project build.gradle files:

dependencies { 
classpath 'com.android.tools.build:gradle:3.1.3'
classpath 'com.google.gms:google-services:4.0.1' }

In your app build.gradle files:

//Firebase Dependencies
implementation "com.google.firebase:firebase-messaging:17.0.0"
implementation "com.google.firebase:firebase-core:16.0.0"
implementation "com.google.firebase:firebase-config:16.0.0"
implementation 'com.google.firebase:firebase-perf:16.0.0'

...} apply plugin: "com.google.gms.google-services"

Databinding is set to true as well:

dataBinding {
    enabled = true
}

Android Studio version: 3.1.2

Thank you all for providing various ways you can get around the problem, such as the answer by @Kyle and the medium post link that shows you how to use firebase without google services.

回答5:

Just downgrade your GooglePlay services dependency to 3.2.1 :)

classpath 'com.google.gms:google-services:3.2.1'

回答6:

While not a great solution, I followed the recommendation from a Googler mentioned on the bug tracker.

I am using

com.google.gms:google-services:3.3.1

I have enabled databinding

`dataBinding.enabled true`

I removed the plugin reference from the app gradle script

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

And followed the recommendations from this Medium post to include all of the necessary Google Service string values.

My app builds successfully and everything works as expected.

回答7:

Everything worked after I added the google() maven inside the allProjects block in my project build.gradle like this:

buildscript {
    repositories {
        jcenter()
        mavenCentral()
    }
    dependencies {
        ...
    }
}

repositories {
    ...
}

// You need to add the google maven in this block.
allprojects {
    repositories {
        jcenter()
        google()
    }
}
