On one of my ktor projects, updating the ktor dependency from 1.3.1 to 1.3.2 *hugely* increases the compile time. Normally `./gradlew classes` takes 40-50s from a clean workspace with ktor 1.3.1. I've been waiting 8 minutes so far on 1.3.2... Is this a known issue?

20 min and counting; I  think I'll stick with 1.3.1 for now...

For me such long builds were often a symptom of memory issues — the GC would be taking so much time it doesn’t allow task to finish. Did you try a clean daemon?

yes, that's with a clean daemon each time.

The profile shows the issue isn't GC; C++ stack traces would be dominant if that was happening
