Problems with Java11

[Philipp0205]

Hello,

we update the Java Version of our Project from 8 to 11. This class seems to be missing: com.sun.javafx.css.converters.SizeConverter.

How can I fix this? Thanks!

[elegantShock2258]

can you share your .fxml? do you have javafx11 here ( this is a common problem) , have you imported jfoenix using maven or jar or some other package manager?

I used maven to import the Java 9+ Version of JFoenix. Is there a common fix?

Oh, have you downloaded JavaFX lib? Please notice that jfx is not included in jre.
