Failed to resolve: com.google.firebase:firebase-core-ktx:

Image link containing screenshot of the error I am using Kotlin for my android app. I am unable to finish my Gradle Build due to this error : Failed to resolve: com.google.firebase:firebase-core-ktx:

I tried all possible solutions available on stackoverflow. I have already downloaded the latest google play services from the SDK manager. I placed maven{url...} in my all repositories, yet can't fix this error. Even tried adding version specification in my implementations. Please help me with this!!

This below is my build.gradle file :-

buildscript {
    ext.kotlin_version = "1.4.21"
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath "com.android.tools.build:gradle:4.1.1"
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
        classpath 'com.google.gms:google-services:4.3.4'

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

allprojects {
    repositories {
        jcenter()
        maven { url "https://maven.google.com" }
    }
}

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

These are the dependencies added to the code :-
