Warning: configuration 'compile' is obsolete and has been replaced with 'implementation' and 'api'.

Question

Problem :

I have already replaced every occurrence of a compile by implementation in the project's build.gradle, but I am still facing below warning :

“Warning: configuration 'compile' is obsolete and has been replaced with 'implementation' and 'api'”

I also tried to look for a "compile" in a whole project but no match was found. So what is the cause of the warning?

Answer 1

I have updated my com.google.gms:google-services from 3.1.1 to 3.2.0 and a warning stopped appearing.

Please find below code for your reference :

 

buildscript {

repositories {

        google()

        jcenter()

    }

    dependencies {

        classpath 'com.android.tools.build:gradle:3.1.0'



    // NOTE: Do not place the application dependencies here; they belong

    // in a individual module build.gradle files



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

    }

}

OR

I encounter same problem without using com.google.gms:google-services. A solution solving this kind problem is as follows:

1. Please check your build.gradle files of all projects and modules. Or you can just global search with key word 'compile' to find where is a cause of  this warning.

2. If above method is unable to solve your warning, then use a  CLI Command,  ./gradlew assembleDebug -d > gradle.log
need to print detail debug information to the file named gradle.log or any else, as a information is too much. Then search the word "WARNING" to find a position in a gradle.log, usually by this way you can find what dependence or plugin causing the warning.

Answer 2

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'
    }
}

 or You can do this way : Follw the below steps

1) Use the new dependency configurations in gradle file Replace ‘compile’ with an ‘implementation’

dependencies {
    compile 'com.android.support:support-v4:27.0.3'
}

this should be like :

dependencies {
    implementation 'com.android.support:support-v4:27.0.3'
}

2) And Replace ‘testCompile’ with an ‘testImplementation’.

testCompile 'junit:junit:4.12'

this should be like :

testImplementation 'junit:junit:4.12'

3) For library replace compile with api

4) Upgrade classpath com.google.gms:google-services to classpath ‘com.google.gms:google-services:3.2.0’ in file in build.gradle (Use latest one)

5) File -> Invalidate Cache
