How to fix the dependencies of a Maven JavaFX project ? (VsCode) - json

Question

I have tried several ways to make the UI of a board game and JavaFX seems to be easiest option. So I created a new Java project using Maven in VsCode with a JavaFX archetype. But now that I copied my java files and Maven dependencies, it seems that there are conflicts with some libraries. I get errors like :
"The package javax.swing is not accessibleJava(268436910)", or
"The type com.fasterxml.jackson.databind.ObjectMapper is not accessibleJava(16778666)"
Here is my pom.xml :
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

I haven't modified my files to use javafx yet, so some libraries will be replaced, but others won't, such as Json libraries. In any case, I hope it can help someone in the same situation.
I looked for version conflicts, but mvn dependency:tree is successful :

I also looked for answers on the net but that's a very specific topic, so haven't found anything yet. That's why I'm asking you guys. I'm not very experienced so I hope I gave enough information

Sorry if I'm late to answer, I forgot to post this. I found the answer with the help of #jewelsea. I was missing these lines in my module-info.java :
requires com.fasterxml.jackson.databind;
opens com.monopoly to javafx.fxml, com.fasterxml.jackson.databind;
