compile an run the starter project from github

Ahpuch — Tue, 24 Oct 2023 11:01:57 GMT

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!

There will be a setting somewhere in IntelliJ that needs correcting... I could try to diagnose this, but there is a much nicer way of getting going with the product. The zip approach is probably the hardest way of getting going and isn't what I'd recommend for a new project unless there is a particular reason.

What I'd recommend is following the gradle starter project approach - you'll likely have it working very quickly and its a much more modern approach to building apps.

It's also worth noting we've got 200+ samples using the gradle approach in this git repository.

Does this help? Happy to assist with the zip approach, but its not what I'd recommend if you can avoid it.
