classNotFoundException: jfxtras.scene.control.CalendarTimeTextField

I want to use jfxtras CalendarTimeTextField in my JavaFX application.

I added jfxtras-common-17-r1.jar and jfxtras-controls-17-r1.jar in classPath. I added the CalendarTimeTextField in SceneBuilder.

I saved the FXML in SceneBuilder and refresh the project in Eclipse (2023-06).

Eclipse VM arguments:

--module-path "C:\Program Files\Java\openJDK\javafx-sdk-20.0.1\lib" --add-modules=javafx.controls,javafx.graphics,javafx.base,javafx.fxml,javafx.web,javafx.swing --add-exports=javafx.controls/com.sun.javafx.scene.control.inputmap=ALL-UNNAMED

After running the application in Eclipse, I get a ClassNotFound Exception

ClassNotFoundException: jfxtras.scene.control.CalendarTimeTextField

I use openJDK20.0.1, JavaFX20, JavaFX Scene Builder 20.0.0

Any ideas what's going wrong?

Thanks GGK

Checked it by myself. The jfxetra libraries aren't configured in run configurations -> Dependencies Tab

added there and it runs.
