Error running JavaFX Jar file built from NetBeans using Maven - maven

Question

I'm using the current NetBeans, and have just created a simple JavaFX project with the Maven compiler.
It runs, cleans, builds etc. perfectly fine, no errors, when in NetBeans.
However, when I navigate to the folder "...Documents\NetBeansProjects\Simple Banking Application\target" and run the executable Jar file, nothing happens. So I tried to run it manually via command line (Java -jar file.jar) it shows me the reason is because of an error:
No main manifest attribute
After searching, I found a supposed solution, involving adding these few lines to the POM.xml:
<plugin>
<groupId>org.apache.maven.plugins</groupId>
<artifactId>maven-jar-plugin</artifactId>
<version>2.3.2</version>
<configuration>
<archive>
<manifest>
<addClasspath>true</addClasspath>
<mainClass>com.mycompany.mavenproject2.App</mainClass>
</manifest>
</archive>
</configuration>
</plugin>
Unfortunately, that just causes a new error:
Error: Could not find or load main class com.mycompany.mavenproject2.App
Caused by: java.lang.NoClassDefFoundError: javafx/application/Application
I'm at a loss, and I'm wondering if I'm just missing something obvious. A couple of preliminary notes:
-I made sure to set this as my main project in NB
-I'm using default configuration
-I've tried cleaning and building, and just building as well, everything runs without any errors in NB
-I've not modified anything settings-wises
-I did refactor the project from mavenproject2 to Simple Banking Application, but I did so using NB's renaming options so that it does so 'safely'. (For the artifactID I had to remove the whitespaces)
-I've made sure all the .class files and .java files are in the project folder (.java are found in src, .class are found in target>classes)
Just in case, here is my entire POM.xml document:

Answer 1

You don't have the JavaFX components on your module path.
You can use a JDK which includes JavaFX (e.g. Azul JDK FX or Liberica Full JDK).
OR, you can follow the instructions below.
See the section on setting the VM arguments for running a JavaFX application as a jar file.
java --module-path /path/to/javafx-sdk-14/lib --add-modules javafx.controls,javafx.fxml -jar myJar.jar
You are using netbeans + maven, so refer to the official documentation openjfx.io JavaFX and NetBeans: modular with maven for more information. It discusses VM arguments for the Java module system to support JavaFX as well as creating runtime images using jlink.
If you don't know or understand the basics of the Java module system, then you should take some time to study and learn it from an appropriate tutorial. That will help you better understand the command line arguments required for the module system as well as the module-info.java alternative.
See the packaging instructions in the JavaFX tag which provide information on packaging alternatives (e.g. jlink and jpackage).
Use up-to-date software (e.g. JDK/JavaFX 18 and the maven-jar-plugin 0.0.8).
Don't use the maven-jar-plugin addClasspath option to build your jar when you have JavaFX component dependencies. The JavaFX components are not designed to be run from the classpath.
