它仍然没有找到 FXML 位置。我搞砸了输出目录和目录以及进入 FXMLLoader 的 URL 无济于事：

Parent root = FXMLLoader.load(getCl().getResource("fxml/ui.fxml"));

这个应用程序在哪里寻找资源？

目录:

In:

项目 / src / main / java / mypackage / Main.java

项目 / src / main / resources / fxml / ui.fxml

Out:

项目 / 目标 / AppName-1.0-SNAPSHOT.jar

项目 / 目标 / AppName-1.0-SNAPSHOT-shaded.jar

项目 / 目标 / 类 / myPackage / Main.cl

项目 / 目标 / fxml / ui.fxml
