Java Extension IDE Not recognizing Javafx imports. VSCODE App Compiles and Runs

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 (see screen shot below).

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_namehttps://github.com/microsoft/vscode/issues/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);
}
}

Screen Shot:

まず、示されている JavaFX SDK のパスを使用し、提供された Main.java、settings.json、launch.json、tasks.json で診断を再現します。ビルド構成と起動構成が正常に成功しているにもかかわらず、Java 拡張機能が JavaFX の import を見つからないものとして報告する理由を確認します。JavaFX の import に波線のエラー表示が出なくなり、サンプルが引き続きコンパイルおよび実行できれば完了です。
