也许一个迟到的答案,但是,有可能有 javafx 11 maven 项目 + NetBeans 9。
- Maven 不喜欢在主类中扩展应用程序。您应该使用两个类:
主.java:
public class Main {
public static void main(String[] args) {
MainApp.main(args);
}
}
MainApp.java:
import javafx.application.Application;
import javafx.event.ActionEvent;
import javafx.event.EventHandler;
import javafx.scene.Scene;
import javafx.scene.control.Button;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;
public class MainApp extends Application {
public static void main(String[] args) {
launch(args);
}
@Override
public void start(Stage primaryStage) {
primaryStage.setTitle("Hello World!");
String a;
a = new String("test");
Button btn = new Button();
btn.setText("Say 'Hello World'");
btn.setOnAction(new EventHandler<ActionEvent>() {
@Override
public void handle(ActionEvent event) {
System.out.println("Hello World!");
}
});
StackPane root = new StackPane();
root.getChildren().add(btn);
primaryStage.setScene(new Scene(root, 300, 250));
primaryStage.show();
}
}
您的 pom.xml 应如下所示:

这将在netbeans中正常工作,没有任何问题。基本上,您需要做的是启动新的 maven 项目,完成设置项目后,只需替换 pom.xml。
这样,您的代码将从 IDE 运行,并将正确编译,以便您可以使用 java --jar 从命令行运行它。此外,您将能够运行 NB 调试器。
