Unable to import Room database for use in Android app

I am working on developing an Android app through android studio and I am trying to implement a Room database. I was using https://developer.android.com/training/data-storage/room for instructions as well as https://medium.com/mindorks/using-room-database-android-jetpack-675a89a0e942, however I was unable to properly import it in. Trying import androidx.room.*; returns cannot resolve symbol 'room'. I was unable to find a solution to this issue.

I have tried:

Project Gradle File:

allprojects {
    repositories {
        jcenter()
        google()
    }
}

App Gradle File:

dependencies {
    implementation 'androidx.appcompat:appcompat:1.2.0'
    implementation 'com.google.android.material:material:1.2.1'
    implementation 'androidx.constraintlayout:constraintlayout:2.0.4'
    implementation 'androidx.legacy:legacy-support-v4:1.0.0'
    testImplementation 'junit:junit:4.+'
    androidTestImplementation 'androidx.test.ext:junit:1.1.2'
    androidTestImplementation 'androidx.test.espresso:espresso-core:3.3.0'

    def room_version = "2.2.6"
    implementation "android.arch.persistence.room:runtime:$room_version"
    annotationProcessor "android.arch.persistence.room:compiler:$room_version"
}

Edit: I have also tried this without success, as well as using room_version as 1.0.0

def room_version = "2.2.6"
implementation "androidx.room:room-runtime:$room_version"
annotationProcessor "androidx.room:room-compiler:$room_version"

Edit: While gradle syncing, I found that it got stuck on Download room-runtime-2.2.6.pom... for 10-15 minutes, and once it completed it showed the warnings:

Unable to resolve dependency for ':app@debugUnitTest/compileClasspath': Could not resolve androidx.room:room-runtime:2.2.6.

Clicking show details did not direct it anywhere

You need to use androidx dependencies. you already using using androidx artifact so you have to use same for Room. Also its mentioned in docs.

def room_version = "2.2.6"
implementation "androidx.room:room-runtime:$room_version"
annotationProcessor "androidx.room:room-compiler:$room_version"
