Gradle Plugin 3.0 Output Apk directory not available

[md]

Android Studio 3.0 definitely is an improvement.

But Gradle Plugin 3.0 broke my builds.

We have all seen: 

https://developer.android.com/studio/build/gradle-plugin-3-0-0-migration.html

But the section: "Modifying variant outputs at build time may not work"

Includes the following snippet:

android.applicationVariants.all { variant ->
     variant.outputs.all {
        outputFileName = "MyCustomApkFileName.apk"
   }
}

So how do we configure the output directory where "MyCustomApkFileName.apk" is finally placed?

No solutions offered in the release.
