How to fix Plugin with id ‘com.github.dcendents.android-maven’ not found. in android studio

In top level build.gradle dependencies, paste this classpaths.
I wonder why cant i’ve seen this method in websites.
Anyway, I fixed it using this way.

dependencies {
    //YOUR DEPEDENCIES
    classpath 'com.github.dcendents:android-maven-plugin:1.2'
    classpath 'com.jfrog.bintray.gradle:gradle-bintray-plugin:1.2'
    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}
