Gradle DSL method not found: 'runProguard'

The error appears when running Android Gradle:

Gradle DSL method not found: 'runProguard'

to fix it open app/build.gradle and fix this part as such:

    buildTypes {
        release {
            // runProguard false // not supported            

             minifyEnabled false            

             proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'

        }
    }
