How to run a maven java fx project that includes jfoenix using javafx-maven-plugin

Question

i was trying to create compile my application and create an executable file. as for now i see the best tool to use is javafx-maven-plugin.

i couldn't get it to work, so i started with a basic code that is generated when creating a project according to this.

https://www.youtube.com/watch?v=4vd-RE0X5Lg

https://openjfx.io/openjfx-docs/#maven

the basic example works but when i tried the same structure in my code or by simply adding a code that contains jfoenix to it. it cannot run.

following line seems to be the important line of the error,

Caused by: java.lang.IllegalAccessError: class com.jfoenix.skins.JFXSpinnerSkin (in module com.jfoenix) cannot access class com.sun.javafx.scene.NodeHelper (in module javafx.graphics) because module javafx.graphics does not export com.sun.javafx.scene to module com.jfoenix

how can i fix this?

this is pom i has sofar.

Your question is not quiet clear, but if you need help with the maven pom let me know. If JFoenix works with JavaFX 11 and above it should simply work out of the box. Let me check if it does. — Sri Nithya Sharabheshwarananda, Apr 28 '20 at 03:51
you need to add --add-opens javafx.graphics/com.sun.javafx.scene=ALL-UNNAMED to the jvm arguments ; there is a way to do it in maven, i am not able to get it working. Let me know if it works. — Sri Nithya Sharabheshwarananda, Apr 28 '20 at 05:53

Based on the code you shared : https://github.com/Ealuthwala/javafx-export

I edited and the POM so that it runs, and this is the output I see

I am sharing the POM below, just use this POM and it should work.

Apart from this you must use JDK 11.0.2 or lower. You need to change settings of your IDE to pick up JDK 11.0.2 or lower for this project.

Because you are using features of JFoenix which will not work with a higher version of JDK. Reason is explained here : https://github.com/jfoenixadmin/JFoenix/issues/955

With this you will be able to make this code run on mobile (64-bit android and iPhone ) using GluonVM, and Desktop, Linux, Mac, and web (using JPro), rasberry pie etc. So practically you cannot have any problem with this unless you have a very big reason for wanting to upgrade to Jdk 12. If you give time, may be a year, I am sure JFoenix team will fix it, if it is not done, and you really find JFoenix very useful you can either pitch in and contribute the fixes or use something else.

                            In order to make jfoenix works, it should need less and doesn't need all of these.
                            You may have to go one by one to find what - - add-opens ... you'll need in your case.
                            - - add-opens is for enabling deep-reflection
                            - - add-exports is for direct access

and 0.0.4 version of the plugin can't run at all.. i was using the 0.0.3 version — Eshaka, Apr 28 '20 at 07:21
yes, thats how i ran it, nothing has changed, i can upload my project if you can take a look — Eshaka, Apr 28 '20 at 14:58
@Eshaka yes please give, let me see. Meanwhile download the code I sent and just run it, it will run. Just execute ``mvn javafx:run`` — Sri Nithya Sharabheshwarananda, Apr 28 '20 at 15:10
yes, I tried that. some of the dependencies were not found, so I changed some versions. then it started to work. nut code isn't working — Eshaka, Apr 29 '20 at 00:54
@Eshaka see the answer, I edited it. I have put a screenshot. And any further discussion avoid in comments as it is a stack-overflow guideline not to have extended discussions in the comments.
