JavaFX not available/not working at runtime for NB modules

[stefanofornari]

Apache NetBeans version

Apache NetBeans 30

What happened

Goal: build a NB module which uses JavaFX for the UI.

Understood solution:

1. add a dependency to org-netbeans-libs-javafx in the module pom
2. add the needed dependencies for JavaFX modules (controls, fxml, etc.) in the module pom with scope provided - NB should provide the classes
3. build the module
4. install JavaFX Library for XXX (Linux/Windows/Mac)
5. install the module

What works:
The module compile and installs, but when it tries to run JavaFX, it runs into exception

I would expect the module to pick the libraries in ext, which are available:

It seems instead these libraries are not available unless declared as compile scope.

Language / Project Type / NetBeans Component

No response

How to reproduce

See https://github.com/stefanofornari/nb-ide-restart/tree/ste/test/for_nb_classloading

Did this work correctly in an earlier version?

No / Don't know

Operating System

Linux

JDK

both OpenJDK 21 and Zulu 21.50

Apache NetBeans packaging

Apache NetBeans binary zip

Anything else

I could not find any useful and updated documentation at least on how JavaFX IMplementation for XXX is supposed to work and how to use it either to build a JavaFX application or a module using JavaFX

Are you willing to submit a pull request?

No

Thanks @musebecuda, but I need something that works out of the box. You may have a look at this: JavaFX Toolkit for NetBeans - let me know if you have any issues.
Maybe we won't have any other choice than creating a plugin that works.
