ubuntu 18.10 - how to install JavaFX with java

Question

I have both openjdk8 and 11 installed. Neither comes with JavaFX. I installed both openjfx and libopenjfx-java packages, but can't get my app to work.

sudo apt list --installed| grep jfx

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

libopenjfx-java/cosmic,cosmic,now 11+26-4 all [installed]
libopenjfx-jni/cosmic,now 11+26-4 amd64 [installed,automatic]
openjfx-source/cosmic,cosmic,now 11+26-4 all [installed]
openjfx/cosmic,now 11+26-4 amd64 [installed]

Openjfx unpacks to /usr folder

dpkg-query -L openjfx
/.

/usr/share
/usr/share/doc
/usr/share/doc/openjfx

/usr/share/openjfx/lib/javafx.media.jar
/usr/share/openjfx/lib/javafx.swing.jar
/usr/share/openjfx/lib/javafx.web.jar

Am I supposed to somewhat copy the libraries to java lib folder? Otherwise it does not compile blabbering not existing javafx.* packages

Previously working jar now exits with:

Error: Could not find or load main class helloworld.HelloWorld
Caused by: java.lang.NoClassDefFoundError: javafx/application/Application

EDIT

I might be one step closer thanks to @José Pereda

java --module-path /usr/share/openjfx/lib --add-modules=javafx.controls,javafx.fxml

now throws

Caused by: java.lang.IllegalAccessError: class impl.org.controlsfx.version.VersionChecker (in unnamed module @0x28658d1c) cannot access class com.sun.javafx.runtime.VersionInfo (in module javafx.base) because module javafx.base does not export com.sun.javafx.runtime to unnamed module @0x28658d1c
