NDK warning on build

When initiating a build on the command line, I am seeing a very old NDK warning. I have `ndk-bundle` installed. There is no `local.properties` file at project root. Log:

```bash
Android-CleanArchitecture git:(master) ./gradlew clean build
To honour the JVM settings for this build a new JVM will be forked. Please consider using the daemon: https://docs.gradle.org/4.1/userguide/gradle_daemon.html.
Daemon will be stopped at the end of the build stopping after processing
Configuration on demand is an incubating feature.

> Configure project :data
NDK is missing a "platforms" directory.
If you are using NDK, verify the ndk.dir is set to a valid NDK directory. It is currently set to /Users/shipit/Library/Android/sdk/ndk-bundle.
If you are not using NDK, unset the NDK variable from ANDROID_NDK_HOME or local.properties to remove this warning.
```

Riproduci l’avviso con ./gradlew clean build e inizia ispezionando la configurazione di build di :data e le impostazioni NDK segnalate. Determina perché la build controlla ndk-bundle nonostante non esista alcun file local.properties; il lavoro è completato quando la build termina senza l’avviso relativo al NDK obsoleto.
