Javafx imports reported as not found by IDE - App Compiles and Runs

[AlexanderAdelAU]

This test app compiles and runs, but after 2 days of trying I cannot get rid of the wavy red lines to all references to javafx. The class file does not show any error. Also, Intellisense works and javafx is recognised until you hit enter and then the wavy line appears.

I have included first line of "Problems" along with launch, tasks and settings json files.

For example:
[{
"resource": "/c:/Development-C/VSCode/Workspaces/Java/SimpleWindow/src/Main.java",
"owner": "generated_diagnostic_collection_name#1",
"code": "errors(1): 1:8-1:14",
"severity": 8,
"message": "package javafx.application does not exist",
"startLineNumber": 1,
"startColumn": 8,
"endLineNumber": 1,
"endColumn": 14
},

Source Code:
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.stage.Stage;
import javafx.scene.layout.StackPane;

public class Main extends Application {
@OverRide
public void start(Stage primaryStage) {
primaryStage.setTitle("Hello World");

    Button btn = new Button("Close");
    btn.setOnAction(e -> primaryStage.close());

    StackPane root = new StackPane();
    root.getChildren().add(btn);

    Scene scene = new Scene(root, 300, 200);

    primaryStage.setScene(scene);
    primaryStage.show();
}

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

}
