building (or running) a javafx project

I am trying to build a javafx project (written by me a few years ago). All works well when I use java8 (this was the version the project was developed with), but I cannot get to build it with newer java version (tried with versions 11 and 13). The errors I get are the following:

daltonism/Daltoniser.java:5: error: package javafx.beans does not exist
import javafx.beans.InvalidationListener;
                   ^
daltonism/Daltoniser.java:6: error: package javafx.application does not exist
import javafx.application.Application;

(a lot of errors like this)

It looks like javafx is not (properly) installed. But I have installed it, here is my java-related package:

java-environment-common 3-2
java-openjfx 13.u14-1
java-runtime-common 3-2
java11-openjfx 11.0.3.u1-1
java8-openjfx 8.u202-3
jre-openjdk 13.0.2.u8-1
jre-openjdk-headless 13.0.2.u8-1
jre11-openjdk 11.0.6.u10-1
jre11-openjdk-headless 11.0.6.u10-1
jre8-openjdk 8.u242-1
jre8-openjdk-headless 8.u242-1

The error appears if I set the default java to the 13 (or 11) version:

[xxx]$ sudo archlinux-java get
java-13-openjdk

If I set java to the 8 version, all normally works:

sudo archlinux-java set java8-openjfx. 

I have not looked at characteristics of newer java versions, but I do not expect javafx having changed to the point where none of the previous javafx packages cannot even be found. It must be an installation problem.

You should, because these changes are precisely the reason for this behaviour:
