Why am I getting a warning when I run my code for the lab?

Question

I keep getting this warning:

WARNING: Loading FXML document with JavaFX API of version 20.0.1 by JavaFX runtime of version 20

Do I need to do anything about it?

Answer 1

TLDR; "Don't worry about it!"

I think the version of SceneBuilder that you downloaded is a tiny bit newer than the version of the JavaFX libraries that we are downloading using Maven.

This (very small) difference in versions between the declared version of the FXML file and the actual version of JavaFX that we are using is very unlikely to pose any problems.
