05/17/2022, 12:57 PMDid you try to update coroutines to 1.6.1 ?

05/17/2022, 1:27 PMHuh, weird. I know where it might be coming from, but I have no idea why.
I'll have a quick look later today, thank you for the reproducer

But yeah, I'm almost sure it's related to an outdated coroutines version. The method it's complaining about should be present in coroutines 1.6.0 (issue), but it seems that for some reason Dokka sees coroutines <=1.5.2 on the classpath... No idea why at the moment

05/17/2022, 2:10 PMSpring boot 2.6.7 seems to be using coroutines 1.5.2: https://github.com/spring-projects/spring-boot/blob/5abc680c7dffec632c521c5ed66cc3[…]aec79/spring-boot-project/spring-boot-dependencies/build.gradle
They've migrated to 1.6.1 in 2.7.0, but it hasn't been released yet 😞

05/17/2022, 2:13 PMWe'll think how to avoid such problems in the future, I guess not everyone migrates to the latest coroutines straight away. Thanks for reporting the problem!
You can try locking coroutines 1.6.0/1.6.1 in your buildscript somehow, i.e make spring use newer coroutines, maybe it'll work
Or just downgrade to Dokka 1.6.10, it should work 🙂 There are some visual enhancements missing, but it'll be enough for you to get acquainted with Dokka
