Android google services plugin version conflict

Question

I recently upgraded Android Studio to 3.1 and I am tuck with version conflict problem.My Gradle version is 4.4 and Andoid plugin version is 3.0.0. I tried changing it to 3.1.1.It gets reverted back to the previous version mumber. It is getting confusing for me,so your help is needed. When syncing I get the following message in the Build.

Version Conflict:

Please fix the version conflict either by updating the version of the google-services plugin (information about the latest version is available at https://bintray.com/android/android-tools/com.google.gms.google-services/) or updating the version of com.google.android.gms to 11.4.2.

build.gradle/app

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

Move this line at last apply plugin: 'com.google.gms.google-services'

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "com.globemaster.samples"
        minSdkVersion 16
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        multiDexEnabled true
        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'])
    //
    //
}
apply plugin: 'com.google.gms.google-services'

At the bottom of the (app)build.gradle script and rebuild the project.

Note:- I think that it has to do something with referencing dependencies that have not yet been created. Something like calling a variable before you even declare it

Answer 2

请在您的应用程序构建gradle.file中添加以下代码

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

Answer 3

I hope this will work for you

Change your classpath to 3.1.1

classpath 'com.android.tools.build:gradle:3.1.1'

And apply plugin after dependencies in app gradle file

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