I have this classical issue: Using JavaFX 11 with OpenJDK 11 together with Eclipse IDE.
Error: JavaFX runtime components are missing, and are required to run this application
I have OpenJDK 11.0.2
dell@dell-pc:~$ java -version
openjdk version "11.0.2" 2019-01-15
OpenJDK Runtime Environment 18.9 (build 11.0.2+9)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.2+9, mixed mode)

Answer:
Your problem is not compiling the project, but running it. Since your main
is defined in your Application
-extension, running the project will require JavaFX in your module path on startup.
So either outsource your main
into a class different from your Application
or add the JavaFX modules with VM arguments:
--module-path="<javafx-root>\lib" --add-modules="javafx.base,javafx.controls,..."
See this for some more info.
