Why is butterknife 9.0.0-SNAPSHOT not resolving?

Question

I want using AndroidX library and below is my Gradle setup for Butterknife

 annotationProcessor 'com.jakewharton:butterknife-compiler:9.0.0-SNAPSHOT'

Plugin

apply plugin: 'com.jakewharton.butterknife'

Project Dependency

dependencies {
      classpath 'com.android.tools.build:gradle:3.3.0-alpha09'
      classpath 'com.google.gms:google-services:4.0.1'
      classpath 'com.jakewharton:butterknife-gradle-plugin:9.0.0-SNAPSHOT'
      // NOTE: Do not place your application dependencies here; they belong
      // in the individual module build.gradle files
    }

Project Repository

repositories {
        google()
        mavenCentral()
        maven { url "https://oss.sonatype.org/content/repositories/snapshots" }

First of All, I'd like to acknowledge @intellij-amiya and @Nabster valuable contribution as this answer is based on the ones they provided.

My Gradle setup is as follows

...
apply plugin: 'com.jakewharton.butterknife'
....
dependencies{
    implementation 'com.jakewharton:butterknife:9.0.0-SNAPSHOT'
    annotationProcessor 'com.jakewharton:butterknife-compiler:9.0.0-SNAPSHOT'
}
...

    // Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

    repositories {
        google()
        mavenCentral()
        maven {
            name 'Sonatype SNAPSHOTs'
            url 'https://oss.sonatype.org/content/repositories/snapshots/'
        }
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.3.0-alpha09'
        classpath 'com.google.gms:google-services:4.0.1'
        classpath 'com.jakewharton:butterknife-gradle-plugin:9.0.0-SNAPSHOT'

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

allprojects {
    repositories {
        google()
        jcenter()
        mavenCentral()
        maven {
            name 'Sonatype SNAPSHOTs'
            url 'https://oss.sonatype.org/content/repositories/snapshots/'
        }
    }
}

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