Shadowing javafx into jar, Forge not loading mod

[gwoonryan]

Hi, I am currently coding a mod that needs javafx as dependency, but whatever i try it just doesn't want to load or build my mod... If i import any of the javafx classes in my mod, the mod just stops working.
To get javafx into the mod i shadow all of the dependencies into the jar with the code below but the build task errors with the error below... Does someone know what i am doing wrong?

I also tried just putting the javafx jars in my mods folder but that didn't work, so i think i have to shadow them in...

Also sometimes when i change the way i shade the dependencies it does build the mod, but Forge fails to load it, forge gives me the error listed under the other error...


For extra info: i am able to build the jar perfectly fine without the shading
 

configurations {
    shade
    compile.extendsFrom(shade)
}

dependencies {
    shade "org.openjfx:javafx-web:19:win"
    shade "org.openjfx:javafx-graphics:19:win"
    shade "org.openjfx:javafx-controls:19:win"
    shade "org.openjfx:javafx-base:19:win"
}


shadowJar {
    dependencies {
       
    }
    configurations = [project.configurations.shade]
    duplicatesStrategy DuplicatesStrategy.EXCLUDE //prevent duplicates
    classifier "" //prevent creation of unshadowed jar
}

reobf {
    //reobfuscate the shadowed jar
    shadowJar {}
}

The game crashed whilst there was a severe problem during mod loading that has caused the game to fail Error: net.minecraftforge.fml.common.LoaderException: java.lang.ClassNotFoundException: me.gwoonryan.videoplayer.VideoPlayer

(VideoPlayer is the main class that imports javafx classes)

The recommended method to do this now is through the JarInJar system. There are docs for it, but I recommend using the mdk as an example to add them.
