State of Kotlin Support in Spring by Sébastien Deleuze

Spring boot and kotlin with maven doesnt work?? I cant run a blank project with vscode or eclipse or intellij... dependcy errors at start and cant import in main or dosnt found main class... heelp me pls

Will JPA ever support webflux?

I was reading the spring boot 2.4 new features in the github and I could not find anything about the kotlinx.serialization support.
Is it supposed to be there?
