将fxml文件包含在可执行jar中 [英] Include fxml file to executable jar

问题描述

我正在尝试创建一个jar文件，但是当我尝试运行它时，我得到 java.lang.IllegalStateException：未设置位置。

i'm trying to create a jar file but when i attempt to run it i'm getting java.lang.IllegalStateException: Location is not set.

这是我在代码中加载它的方式：

This is how it is loaded it in my code:

 FXMLLoader loader = new FXMLLoader(Main.class.getResource("/view/MainView.fxml"));

jar文件是使用intellij构建的：项目结构 - >工件

jar file is built using intellij idea : Project Structure -> Artifacts

已解决

我已设法通过添加

   <resources>
        <resource>
            <directory>src/main/resources</directory>
            <includes>
                <include>**/*.fxml</include>
                <include>**/*.css</include>
            </includes>
        </resource>
    </resources>

和maven-assembly-plugin

and maven-assembly-plugin

推荐答案

通过IDE构建项目不是一个好主意。它会更改项目的目录结构，因此您的fxml文件的相对路径不再正确。如果使用Maven构建项目，则应该解决该问题。然后将 maven-compiler-plugin 添加到生成的pom.xml中。

Building your project via your IDE isn't a good idea. It changes the directory structure of your project, so your relative path to the fxml file isn't correct anymore. You should get rid of that problem if you build your project with Maven. Then add the maven-compiler-plugin to your generated pom.xml.

<plugins>
    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        ...
    </plugin>
...
</plugins>
