Describe the bug
Until about 1-2 months ago i can use nativescript without problem, today i try to build an old project and i receive this error:

• Where:
  Build file '[cut]\platforms\android\app\build.gradle' line: 33

• What went wrong:
  A problem occurred evaluating project ':app'.

Plugin with id 'com.android.application' not found.

So i tried to build an "hello world" project and i receive the same error. What happened? In these 2 months i start to coding in Native Android Studio. Is possible i changed something?

Beginne mit dem gemeldeten Fehler in platforms/android/app/build.gradle in Zeile 33 und überprüfe dann die Versionen der NativeScript- und Android-Komponenten anhand von tns info oder package.json. Reproduziere den Fehler sowohl im alten Projekt als auch in einem neuen Hello World-Projekt. Als erledigt gilt die Aufgabe, wenn der Android-Build das application plugin auflöst und erfolgreich abgeschlossen wird.
