Allgemeines
Installation
Download von https://gluonhq.com/products/javafx/
zip-Paket entpacken, Laufwerk oder Ordner beliebig
In IntelliJ Idea
1. File -> Project Structure -> Libraries
Den lib Ordner des entpackten JavaFX einbinden.
2. In Edit Configurations VM Options eintragen:
Linux/MAC:
--module-path /path/to/javafx-sdk-15.0.1/lib --add-modules javafx.controls,javafx.fxml
(Padangabe anpassen)
Windows:
--module-path "\path\to\javafx-sdk-15.0.1\lib" --add-modules javafx.controls,javafx.fxml
(Padangabe anpassen)
Troubeshooting
module javafx.base not found
> Prüfen, ob in Run > Run Configuration > VM Options
der Pfad zum lib-Verzeichnis von JavaFX richtig gesetzt ist.
