Cannot resolve external dependency com.android.tools.build.gradle:4.0.1 because no repositories are defined.

Answer 1

In your buildscript block you have to add the repositories also.
Something like:

buildscript {
    repositories {
        google()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.0'
    }
}

Answer 2

It is probably 2 years too late, but for me the solution was adding

allprojects {
repositories {
    jcenter()
    google()
}

at the end of build.gradle file with buildscript
