anyone know of a good example of gradle kotlin dsl building a spring boot app?

Not self promoting or anything, but this is a small example: https://github.com/AlexCzar/db-info-demo I plan to update everything to latest versions today (in couple of hours probably).

You can check @s1m0nw1's repo with a SpringBoot Webflux example. https://github.com/s1monw1/SpringWebFluxKotlin or mine 🙂 https://github.com/TimRiemer/KotlinBootReactive

excellent! just the links I was looking for! thanks
