错误：缺少JavaFX运行时组件，包含IntelliJ Idea、Maven和JDK19


问题是当我尝试运行我的主类时，我从上面得到错误。我正在使用Intellij IDEA

在pom. xml中添加了依赖项和插件运行mvn清洁安装，也运行mvn清洁javafx：run但我无法运行我的主类

这是我给pom加的

<dependency>
  <groupId>org.openjfx</groupId>
  <artifactId>javafx-controls</artifactId>
  <version>19</version>
</dependency>

<dependency>
  <groupId>org.openjfx</groupId>
  <artifactId>javafx-fxml</artifactId>
  <version>19</version>
</dependency>

<plugin>
  <groupId>org.openjfx</groupId>
  <artifactId>javafx-maven-plugin</artifactId>
  <version>0.0.8</version>
  <configuration>
    <mainClass>App</mainClass>
  </configuration>
</plugin>

我建议从IntelliJ IDEA创建的一个明确针对JavaFX的新项目开始。

在新建项目向导中使用Generators列表中的JavaFX选项。

您将获得一个成功运行的完整工作示例应用程序。

代码使用module-info.java文件模块化。

示例应用程序使用FXML。如果您愿意，您可以轻松删除它。您可以只使用Java编码而不使用任何FXML标记编码-

POM如下所示。请注意包含OpenJFX依赖项。

顺便说一句，您可以替换属性

<!-- https://mvnrepository.com/artifact/org.junit.jupiter/junit-jupiter -->
<dependency>
    <groupId>org.junit.jupiter</groupId>
    <artifactId>junit-jupiter</artifactId>
    <version>5.9.1</version>
    <scope>test</scope>
</dependency>
