Still getting warning : Configuration 'compile' is obsolete and has been replaced with 'implementation'

I've updated com.google.gms:google-services from 3.1.1 to 3.2.0 and the warning stopped appearing.

buildscript {

    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.0'

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files

    classpath 'com.google.gms:google-services:3.2.0'
    }
}

I have one same Warning caused to com.google.gms:google-services.

The solution is to upgrade classpath com.google.gms:google-services to classpath 'com.google.gms:google-services:3.2.0' in file in build.gradle Project:

buildscript {
    repositories {
        jcenter()
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.0'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
        classpath 'com.google.gms:google-services:3.2.0'
    }
}

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

task clean(type: Delete) {
    delete rootProject.buildDir
}

In Android Studio verion 3.1 dependencies complie word is replaced to implementation

dependencies with Warning in android studio 3.1

dependencies {
            compile fileTree(dir: 'libs', include: ['*.jar'])
            compile 'com.android.support:appcompat-v7:27.1.0'
            compile 'com.android.support.constraint:constraint-layout:1.0.2'
            testImplementation 'junit:junit:4.12'
            androidTestImplementation 'com.android.support.test:runner:1.0.1'
            androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'
    }

dependencies OK in android studio 3.1

    dependencies {
            implementation fileTree(dir: 'libs', include: ['*.jar'])
            implementation 'com.android.support:appcompat-v7:27.1.0'
            implementation 'com.android.support.constraint:constraint-layout:1.0.2'
            testImplementation 'junit:junit:4.12'
            androidTestImplementation 'com.android.support.test:runner:1.0.1'
            androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.1'

    }

Gradel generate by Android Studio 3.1 for new project.
