Cannot run native image for JavaFX+Spring Boot project

[palexdev]

I have an app built with Spring Boot and JavaFX. I need to distribute my app on all major platforms, and I'd like to use GraalVM to generate native images. However, little did I know the process would be so underwhelming, I tried everything, but I can't make this work, it's so difficult

I have made a little reproducer, available here: Reproducer.zip

I can't run the app because I get this exception:

Also note that I can't run the nativeRunAgent task because I recieve an exception of type UnsupportedOperationException with no message, so I don't know what's causing it

YOOOO?? ANYBODY HERE??? Where the heck is support? There is a mountain of issue here without any answer
I believe #159 needs to be merged ASAP

Hi! Have you solved the problem?

[palexdev]

Hi! Have you solved the problem?

Yes, by not using Spring, replaced by Inverno

Also, if you wanna know the outcome, I was able to consistently build native images but they are very buggy
So I ended up using JLink
