Gradle can not find firebase auth ktx library in android

Question

As you can see below, I have encounter this error when I try to download missing files inside firebase auth.ktx library otherwise I can not reach any document written about classes, methods or properties.

this is my Project built file

    ext {
        compose_version = '1.2.0-alpha05'
    }
    dependencies {
        classpath 'com.google.gms:google-services:4.3.10'  // Google Services plugin

Answer 1

The correct download URL is https://maven.google.com/com/google/firebase/firebase-auth-ktx/21.0.2/firebase-auth-ktx-21.0.2.aar

I assume you are getting the wrong URLs because you missed to add the Google repository to your project. Add in your top-level build file build.gradle the following section:

allprojects {
    repositories {
        google()
        mavenCentral()
    }
}
