I am not able to add the GitHub repository of Youtube video extractor for exoplayer, implementing in android studio project.

build.gridle(abc app)

buildscript {
    repositories {
        google()
        jcenter()

    }

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

allprojects {
    repositories {
        google()

        maven { url "https://jitpack.io" }

When I'm trying to add the "Implementation 'com.github.HaarigerHarald:android-youtubeExtractor:v1.7.0'", I don't know why showing the below error -
