How to build jar file from JavaFX app?

When I build a jar file of a (working in the IDE) JavaFX app, I get this error when trying to start it with java -jar jarfile.jar:

"Error: JavaFX runtime components are missing, and are required to run this application"

I have tried adding the dlls from C:\Program Files\openjfx-19_windows-x64_bin-sdk\javafx-sdk-19\bin to the jar, but it results in the same error.

I also tried adding the dlls from ~\.openjfx\cache\17.0.2-ea (which I assume is the JavaFX SDK IntelliJ uses?) to the jar instead, but this gives me the same result.

Several tutorials I found say that this is how it should work, but I am obviously not clever enough.

What am I doing wrong?

The app works when run inside IntelliJ.
