Interesting ... so they removed some "vital" parts of my plugin :( thanks for reporting this (I wasn't aware that the Gradle-project does change that much)

So is this not going to be fixed?

[debuglevel]

I just looked around in the forks if someone fixed this. I did not verified it, but https://github.com/icebergteam/javafx-gradle-plugin/commit/8ee1e75b57ca784799ebec284604acb02ae03543 looks like @icebergteam fixed something that seems to to be related. Maybe you could take a look if this is indeed a fix?

[FibreFoX]

Thanks for the hint @debuglevel , I will look into it. 2020 was not my best year, so good way for "new year resolutions" 😺

@FibreFoX Can I support you somehow? Donate, perhaps?
