所以我已经被这个问题困扰了好几天了。我在stackoverflow和其他网站上发现并阅读了很多帖子,但没有一个解决方案适合我。我的maven项目中的javafx有问题。我使用Java15和JavaFX15.0.1。以下是我在项目中拥有的文件:pom.xml文件:
<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

<artifactId>javafx-fxml</artifactId>
<version>15.0.1</version>
</dependency>
</dependencies>
</project>
下面是我的main.java类:
package main;
import javafx.application.Application;
import javafx.fxml.FXMLLoader;
import javafx.scene.Parent;
import javafx.scene.Scene;
import javafx.stage.Stage;
public class Main extends Application {
@Override
public void start(Stage primaryStage) throws Exception{
Parent root = FXMLLoader.load(getClass().getResource("src/main/java/resources/mainH/view.fxml"));
primaryStage.setTitle("Hello World");
primaryStage.setScene(new Scene(root, 300, 275));
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
以下是view.fxml文件:
<?xml version="1.0" encoding="UTF-8"?>
<?import javafx.scene.control.*?>
<?import javafx.scene.layout.*?>
<AnchorPane prefHeight="400.0" prefWidth="600.0" xmlns="http://javafx.com/javafx/11.0.1" xmlns:fx="http://javafx.com/fxml/1" fx:controller="controllers.controller">
<children>
<Pane layoutX="200.0" layoutY="100.0" prefHeight="200.0" prefWidth="200.0">
<children>
<Button layoutX="74.0" layoutY="100.0" mnemonicParsing="false" text="Button" />
</children>
</Pane>
</children>
</AnchorPane>
下面是我试图编译代码时弹出的消息:

我看到的大多数关于这个问题的帖子都是通过改变getresource()方法中的目录来解决的,我尝试过这个方法,还有很多其他的解决方案,你可能在pom文件中看到过。我请求你帮忙解决这个问题,因为我不知道该怎么办了。任何帮助都将不胜感激。谢谢你提前帮忙。

感谢@jos的评论é佩雷达我找到了解决问题的办法。问题是缺少javafxmaven插件和vm参数。
