We're writing new apps in Kotlin instead of Java, works fine for us. shrug Vert.x , Ktor apps, Kafka streaming apps. IDEA handles it absolutely fine these days, I suspect you last tried it sometime ago.

Can't comment on the Gradle stuff though, I vastly prefer Maven.

Is vertx better than ktor for production?

[EdwardDiego]

Vert.x is doing us well for high volume apps, Ktor is early stages but looks alright also. That said, haven't benchmarked identically feature compete implementations of the same app in both, so don't really have the metrics to properly compare, but so far at least, it seems comparable.
