如何将 JavaFX 项目正确转换为 Maven？

Question

我在 Eclipse 中编写了 JavaFx 项目 IDE，它工作正常。

将其转换为 Maven 项目后，我的 FMXL 文件停止打开。但是，如果我创建新的 FXML 文件并将它们放在相同的文件夹中，一切正常。

有什么方法可以运行我的 Maven 项目而不用重新创建我所有的 FXML 文件吗？

我已经尝试过在代码中更改我的 FXML 文件的路径，将 FXML 移动到 src/main/resources 包或只是将代码从旧的 FXML 复制到新的 FXML，但没有任何效果。

我在 SceneBuilder 中创建的所有 FXML，并且在整个过程中没有更改此程序的版本。

我正在使用以下方法加载我的 FXML：

private void showMainPage() throws IOException {
FXMLLoader loader = new FXMLLoader();
loader.setLocation(Main.class.getResource("view/MainView.fxml"));
mainLayout = loader.load();
Scene scene = new Scene(mainLayout);
primaryStage.setScene(scene);
primaryStage.show();
}

Answer 1

这与 Maven 无关，这是由于您的应用程序 Java 模块系统配置不正确导致的访问错误。

错误信息告诉你哪里出了问题：

module rslFxNewMaven does not "opens reselection.view" to module javafx.fxml

学习 -> java modules.

将以下行添加到您的模块中-info.java:

opens reselection.view to javafx.fxml;
