Android studio 3.0.1 ошибка в сборке gradle

Question

Я реализовал изменение варианта, также представленное на сайте Android Studio, но не могу выяснить проблему.

Error:Cannot set the value of read-only property 'outputFile' for ApkVariantOutputImpl_Decorated{apkData=Main{type=MAIN, fullName=APPCDebug, filters=[]}} of type com.android.build.gradle.internal.api.ApkVariantOutputImpl.
