Program type already present: com.google.android.gms.common.util.VisibleForTesting -':app:transformDexArchiveWithExternalLibsDexMergerForDebug' [duplicate]

Question

I am getting this error whenever I try to run a program in Android Studio 3.1.2.

Program type already present: com.google.android.gms.common.util.VisibleForTesting Message{kind=ERROR, text=Program type already present: com.google.android.gms.common.util.VisibleForTesting, sources=[Unknown source file], tool name=Optional.of(D8)}

My gradle Module app :

buildscript {
repositories {
    google()
    jcenter()

    maven {
        url "https://maven.google.com" // Google's Maven repository
    }
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.1.2'
    classpath 'com.google.gms:google-services:3.2.1'

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

}

allprojects {
repositories {
    google()
    jcenter()

    maven {
        url "https://maven.google.com"
    }
    maven {
        url "https://maven.fabric.io/public"
    }
}

}

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

}

If the issues persists after updating the google play gradle plugin version to latest version, search for the given file in the entire project using the Android Studio File Search and look for the searches with the same package name. The issue was that the file with the same package and file name was present in two different jars (In my case, one jar was of old google analytics services jar which had been manually downloaded and added as a library in the project). Please check image for clarity. We have to resolve this conflict (I had removed my old jar as it was no longer needed) and the project would build.
