maven cannot find javafx 11 when compiling an eclipse application - eclipse

Question

I have an eclipse application using javafx 11. For lack of better solution, I have javafx installed in /opt/javafx-sdk-11.0.2, the product definition contains --module-path /opt/javafx-sdk-11.0.2/lib/ --add-modules=javafx.controls as vm arguments, and .classpath contains these lines:
<classpathentry kind="lib" path="/opt/javafx-sdk-11.0.2/lib/javafx.base.jar"/>
<classpathentry kind="lib" path="/opt/javafx-sdk-11.0.2/lib/javafx.controls.jar"/>
<classpathentry kind="lib" path="/opt/javafx-sdk-11.0.2/lib/javafx.graphics.jar"/>
My pom.xml looks like this:

jdk.version is 11, but tried it with 10 as well.
The weird thing about it that I remember I could compile it with maven, but cannot get it to compile now.
The error:

Answer 1

Putting all the jars of javafx to the lib folder of the project, and listing them in classpath helped. But it seems more like a workaround than a solution, and I cannot figure out how to set the launch configuration of the product to be able actually launch it.
