Android Studio build.gradle warning message

After i have successfully updated to Android Studio 3.1 Canary 9 i am getting warning message as

Warning:Configuration 'compile' is obsolete and has been replaced with 'implementation'.
It will be removed at the end of 2018

I know this warning will not cause any problem in my project at least for now. But i want to remove it totally so that there will be no problem in future at all. But after reviewing my build.gradle file i cannot find any line of code which has invoked this warning at all.

Here is my build.gradle file

apply plugin: 'com.android.application'

android {
    compileSdkVersion 27
    defaultConfig {
        applicationId "app.project.virtualdiary"
        minSdkVersion 21
        targetSdkVersion 27
        versionCode 1
        versionName "1.0"
        testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
    }
    buildTypes {
        release {
            minifyEnabled false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
}

dependencies {
    implementation 'com.google.firebase:firebase-auth:11.8.0'
    implementation fileTree(dir: 'libs', include: ['*.jar'])
    implementation 'com.android.support:appcompat-v7:27.0.2'
    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'
    implementation 'com.android.support:support-v4:27.0.2'
    implementation 'com.android.support:support-vector-drawable:27.0.2'
}


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

The problem lies in apply plugin: 'com.google.gms.google-services'

The Google Services plugin is adding a dependency on behalf of you. Hopefully they fix it in the future.

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.

Good luck

I agree with Niklas. I changed the compile to implementation, but the warning was gone only after the change in the build.gradle(Project: .....)

before:

 dependencies {
        classpath 'com.android.tools.build:gradle:3.1.0'
        classpath 'com.google.gms:google-services:3.0.0'
    }

after:

dependencies {
        classpath 'com.android.tools.build:gradle:3.1.0'
        classpath 'com.google.gms:google-services:3.2.0'
    }

first select :

1. Build
2. Clean Project then Build
3. make Project in Android studio

When AndroidManifest.xml package name was different from build.gradle package name i get this error

> Configuration 'compile' is obsolete and has been replaced with > 'implementation'. It will be removed at the end of 2018

Java compile error

Change the "compile" to "implementation". this problem will be fixed! it works on my computer.
