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:

首先，使用提供的 Main.java、settings.json、launch.json 和 tasks.json，以及所示的 JavaFX SDK 路径，复现该诊断。检查为什么 Java 扩展会报告 JavaFX 导入缺失，尽管构建和启动配置都能成功执行。完成标准是 JavaFX 导入不再显示波浪线错误，同时示例仍能编译和运行。
