Hi, i try to run the starter project sample from github (https://github.com/Esri/java-zip-starter-project)
I followed the instructions from https://developers.arcgis.com/java/install-and-set-up/
so finally the single Java Class App compiles without errors or warnings.
But if i run the the App i get a noclassdeffounderror:
Fehler: Hauptklasse com.mycompany.app.App konnte nicht gefunden oder geladen werden
Ursache:
(in englisch: error: main class com.mycompany.app.App could not be found or loaded,
cause: java.lang.NoClassDefFoundError: javafx/application/Application)
i found the Application Class in the javafx.graphics.jar and this jar is also in the build path:

so why doesn't the app start?
any help is appreciated
thank you!
