使用 JavaFX 依赖项运行 jar 文件时出错

问：

我需要创建一个带有依赖项的 jar 文件，以便我可以在没有源代码文件的情况下传输它。但是当您通过双击启动这样的 jar 时，没有任何效果，但是如果您通过命令行以 java -jar 文件.jar 格式运行它，则会出现以下错误：

Exception in thread "main" java.lang.ExceptionInInitializerError

        at sun.reflect.NativeMethodAccessorImpl.invoke(Unknown Source)

这是我的插件代码和启动代码：

<build>
 <plugins>
  <plugin>
   <groupId>org.springframework.boot</groupId>
   <artifactId>spring-boot-maven-plugin</artifactId>
   <executions>
     <execution>
      <goals>
       <goal>repackage</goal>
      </goals>
      <configuration>
    <classifier>spring-boot</classifier>
    <mainClass>
     uip.gui.JavaFxRun
    </mainClass>
      </configuration>
     </execution>
   </executions>
  </plugin>
 </plugins>
</build>

使用 JavaFX 的文件：

public class JavaFXClassFrame extends Application {

    static Logger LOGGER;

    static {
        try (FileInputStream ins = new FileInputStream("src/main/resources/log.config")) {
            LogManager.getLogManager().readConfiguration(ins);
            LOGGER = Logger.getLogger(JavaFXClassFrame.class.getName());
        } catch (IOException e) {
            LOGGER.log(Level.WARNING, "Error ", e);
        }
    }

    public static void main(String[] args) {
        launch(args);
    }

    @Override
    public void start(Stage stage) {
        try {
            FXMLLoader loader = new FXMLLoader();
            URL xmlUrl = getClass().getResource("/fileFxml.fxml");
            loader.setLocation(xmlUrl);
            Parent root = loader.load();
            stage.setScene(new Scene(root));
            stage.show();
            LOGGER.log(Level.INFO, "Success ");
        } catch (Exception e) {
            LOGGER.log(Level.SEVERE, "Error", e);
        }
    }
}

public class JavaFxRun {
    static Logger LOGGER;

    static {
        try (FileInputStream ins = new FileInputStream("src/main/resources/log.config")) {
            LogManager.getLogManager().readConfiguration(ins);
            LOGGER = Logger.getLogger(JavaFxRun.class.getName());
        } catch (Exception e) {
            LOGGER.log(Level.WARNING, "Error ", e);
        }
    }

    public static void main(String[] args) {
        JavaFXClassFrame.main(args);
    }
}

JavaFX 启动文件：

public class JavaFxRun {
    static Logger LOGGER;

    static {
        try (FileInputStream ins = new FileInputStream("src/main/resources/log.config")) {
            LogManager.getLogManager().readConfiguration(ins);
            LOGGER = Logger.getLogger(JavaFxRun.class.getName());
        } catch (Exception e) {
            LOGGER.log(Level.WARNING, "Error ", e);
        }
    }

    public static void main(String[] args) {
        JavaFXClassFrame.main(args);
    }
}
