Question

它仍然找不到FXML位置。我搞砸了输出目录和目录和进入FXMLLoader的URL无效：

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

此应用程序在哪里寻找资源？

在：

PROJECT / src / main / java / mypackage / Main.java

PROJECT / src / main / resources / fxml / ui.fxml

出局：

PROJECT / target / AppName-1.0-SNAPSHOT.jar

PROJECT / target / AppName-1.0-SNAPSHOT-shaded.jar

PROJECT / target / classes / myPackage / Main.class

PROJECT / target / fxml / ui.fxml

Answer 1

对于初学者来说，第一个问题与您的资源有关：

父根= FXMLLoader.load（getClass（）。getResource（“ fxml / ui.fxml”））;

如果使用getResource，则必须使用绝对路径：

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

StackOverflow上对此问题有很多疑问，此answer是非常有效的参考。

maven-shade-plugin

假设您的com.potatospy.NewMain类是不扩展Application的{{3}}，并且您的来源（在src/main/java/下）是：

com / potatospy / NewMain.java
com / potatospy / Main.java
com / potatospy / UIController.java

和您的资源（在src/main/resources下）是

fxml / ui.fxml

如果您想做一个阴影/脂肪罐，而又不修改默认的maven-resources-plugin，那么仅使用maven-compile-plugin和{{1 }}来自pom的插件：

maven-shade-plugin

然后您可以运行您的应用程序：

mvn clean package

请注意，已应用默认资源插件，并且您的文件已添加到java -jar target/AppName-1.0-SNAPSHOT.jar：

target / classes / com / potatospy / NewMain.class
target / classes / com / potatospy / Main.class
target / classes / com / potatospy / UIController.class
target / classes / fxml / ui.fxml

maven-resource-plugin

但是，如果像在pom中一样添加资源插件，则在运行它时，您会注意到文件已添加到：

target / classes / com / potatospy / NewMain.class
target / classes / com / potatospy / Main.class
target / classes / com / potatospy / UIController.class
target / fxml / ui.fxml

打包完成后，甚至没有将fxml文件添加到jar中！

如果需要包括资源插件，则将需要以下内容：

target/classes

请注意，我已将<plugin> <artifactId>maven-resources-plugin</artifactId> <version>3.1.0</version> <configuration> <outputDirectory>${basedir}/target/classes</outputDirectory> <resources> <resource> <directory>src/main/resources</directory> <filtering>true</filtering> <includes> <include>**/*.fxml</include> </includes> </resource> </resources> </configuration> <executions> <execution> <id>copy-resources</id>  <phase>package</phase> <goals> <goal>copy-resources</goal> </goals> </execution> </executions> </plugin>添加到输出目录（因此资源已包含在其中）。

具有阴影的JavaFX构建，需要位置。它在哪里看？
