Quick question that's been bugging me - I'm trying to debug I've searched everywhere and can't find a clear answer....... I'm working on a project and hit a roadblock. I'm experiencing a frustrating scenario in Eclipse 2023-09 where the CSS styles defined for my JavaFX application are not being applied when I load the UI using FXML. I've ensured that the paths to the CSS files are correct, but the styles simply do not seem to take effect. Here's a snippet of my FXML code: ```xml <VBox xmlns:fx="http://javafx.com/fxml" fx:controller="com.example.controller.MainController"> <stylesheets> <URL value="file:src/main/resources/styles/styles.css"/> </stylesheets> <Label text="Hello World" styleClass="header"/> </VBox> ``` And my `styles.css` file contains: ```css .header { -fx-font-size: 24px; -fx-text-fill: #ff0000; } ``` I've tried cleaning the project, restarting Eclipse, and even checking the JavaFX library versions to ensure compatibility with JDK 17. I also verified the CSS file's existence in the specified directory, and it loads correctly when accessed directly through the file path. However, when I run the application, the label doesn't reflect the styles defined in the CSS. Additionally, I checked for any console output and there are no errors indicating that the CSS file failed to load. I'm at a loss here, so if anyone has encountered a similar scenario or has suggestions on how to debug this question further, I would greatly appreciate your insights! For context: I'm using Java on Linux. Am I missing something obvious? For context: I'm using Java on macOS. I'm using Java 3.9 in this project. Thanks for your help in advance! This issue appeared after updating to Java stable. Any ideas what could be causing this?
