java - 无法运行maven javafx应用程序并且pom文件中出现一些错误

Question

我正在尝试在 Maven 下运行 JavaFX 应用程序。当我运行该程序时，它显示一些错误。

Error: Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.2.1:java (default-cli) on project Calculator: The parameters 'mainClass' for goal org.codehaus.mojo:exec-maven-plugin:1.2.1:java are missing or invalid -> [Help 1]

我应该在我的 pom.xml 文件的哪一部分进行更改。

Using netbeans 11.0 
JDK 12 

我尝试在 stackoverflow 上查看一些可用的解决方案。

这是我的 Pom.xml 文件

我在我的pom.xml文件中的Plugins标签下添加了一些代码行。 另外，我还提到了一个 youtube 视频。
