JavaFX could not load @ font face font because com sun. javafx. css. StyleManager loadStylesheetUnPrivileged

I have asked a similar question here, but it seems unclear, because I have a lot of code in the project and can't be published here, so please don't mark it as duplicate

Therefore, I decided to create a new project with just one label, make the code small and clean, and eliminate other potential suspects I got wrong

So here is my java source code

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) throws Exception {
        Group root = new Group();

        Label label = new Label("Sample Label");
        label.setId("sampleLabel");
        root.getChildren().add(label);

        Scene scene = new Scene(root,300,275);
        scene.getStylesheets().add(getClass().getResource("applicationStyles.css").toExternalForm());
        primaryStage.setTitle("Hello World");
        primaryStage.setScene(scene);
        primaryStage.show();
    }

    public static void main(String[] args) {
        launch(args);
    }
}

This is my CSS file

/**/
@font-face {
    font-family:'Roboto';
    src:url("Roboto-Thin.ttf");
}
#sampleLabel{
    -fx-font-family: Roboto ;
}

This is the error I encountered in IntelliJ idea

INFO: Could not load @font-face font [file:/C:/Users/UserName/Desktop/Java8%20projects/TeamViewer/out/production/TeamViewer/sample/Roboto-Thin.ttf]

Thank you. Thank you very much for any help

Solution

I found possible causes and solutions:

It seems that this function cannot use its path / url string Therefore, you need to resolve the path and replace it with spaces This means that you must use code - loaded fonts instead of CSS (now)

In clojure, my work is as follows:

(require '[clojure.java.io :as cio])
(require '[clojure.string :as s])
(-> "fonts/SourceCodePro-Regular.ttf" 
  cio/resource 
  str 
  (s/replace "%20" " ") 
  (javafx.scene.text.Font/loadFont  10.))
