How to run ControlsFX sample application using Java 11 and JavaFX 11

Question

If you want to play with the ControlsFX sample application, simply download the ControlsFX release and run the following command on the command prompt (be sure to replace the * with the actual version number of FXSampler and ControlsFX-samples):

java -jar controlsfx-samples-*.jar

I've downloaded ControlsFX 9.0.0 which is said to be for users of Java 9 and later.

When I run java -jar controlsfx-samples-9.0.0.jar I get

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

But that's OK, as according to Run HelloWorld using JavaFX 11 guide, I have to add modules.

So I try java --module-path "C:\Program Files\Java\javafx-sdk-11\lib" --add-modules=javafx.controls -jar controlsfx-samples-9.0.0.jar and I get

Missing JavaFX application class fxsampler.FXSampler

I execute all commands from controlsfx-9.0.0 directory which contains controlsfx-9.0.0.jar, controlsfx-samples-9.0.0.jar and fxsampler-1.0.10.jar.

Output of java -version for me is:

openjdk version "11.0.1" 2018-10-16
OpenJDK Runtime Environment 18.9 (build 11.0.1+13)
OpenJDK 64-Bit Server VM 18.9 (build 11.0.1+13, mixed mode)

Any comments and suggestions are appreciated.
Thanks in advance.

EDIT:
After following Slaw's advice and running java --module-path "C:\Program Files\Java\javafx-sdk-11\lib" --add-modules=javafx.controls,javafx.fxml,javafx.web -jar controlsfx-samples-9.0.0.jar I get

Similar issue as this other SO thread ? [JavaFX packaging: NoClassDefFoundError](https://stackoverflow.com/questions/52761836/javafx-packaging-noclassdeffounderror) — keybored, Oct 18 '18 at 12:16
@keybored Well, it had been similar before I've added `--add-modules`. And the thread says that the problem was in absence of JavaFX in JDK 11, but https://openjfx.io/ states that ControlsFX supports JavaFX 11, so I guess I have another problem. — DfM, Oct 18 '18 at 12:29
You've added `javafx.controls` which will also pull in `javafx.graphics` and `javafx.base`, but do the samples need any of the other modules? Such as `javafx.fxml` or `javafx.web`? — Slaw, Oct 18 '18 at 12:49
@Slaw You we right. Now I get another exception. I've updated the post. — DfM, Oct 18 '18 at 13:17

Fixed in PR #720. So new Maven artifacts will incorporate the fix.

How does a new Maven artifact help with running it from the command line? – dmolony Nov 26 '18 at 06:16
@dmolony All the jars you download from ControlsFX website are maven artifacts just packed in a zip archive. You can check yourself by downloading [current archive](http://fxexperience.com/downloads/controlsfx-9-0-0/) and comparing the jars in it with [Maven artifacts](https://search.maven.org/search?q=org.controlsfx). – DfM Nov 28 '18 at 12:57
It still doesn't work. I just downloaded the 9.0.0 jars, and gave the command as per the instructions. Error: Could not find or load main class fxsampler.FXSampler – dmolony Jan 15 '19 at 08:25
Then I tried it with the instructions above. Error occurred during initialization of boot layer java.lang.module.FindException: Module javafx.controls not found – dmolony Jan 15 '19 at 08:37

@dmolony 9.0.0 jars are NOT compatible with JavaFX 11. You have to wait for the new ones. As stated on https://github.com/controlsfx/controlsfx: "For users of Java 11 and later, download will be coming soon!" – DfM Jan 23 '19 at 12:30
As the OP's question was about Java 11, and because the accepted answer (this one) says 'Fixed in PR #720', it seemed safe to assume that it was fixed for Java 11. – dmolony Jan 24 '19 at 08:44
@dmolony developers of ControlsFX have made a fix, so that ControlsFX can run on JDK 11, but they haven't built artifacts with that fix included. If you want, you can build ControlsFX on your own. – DfM Jan 24 '19 at 16:59
