We can't use Gradle 9.0.0-rc-1 but 8.14.3 also works so it's not necessary to use a rc version. com.github.stfalcon-studio:StfalconImageViewer v1.0.1 disappeared on jitpack. d11578fe3f is still available but it's better to use another lib since this lib is not maintained for a long time and will disappear anytime.
