not sure this should go here, and it does not seem strictly related to kotlin only, but has anyone seen something like (let me explain in a thread first though)?

I’m using Kotlin in a maven based project, and I’ve run into this. It seems like the Kotlin version is not being configured from the maven pom, so I needed to make sure that I manually configure Kotlin in the IDEA settings in parallel. That’s a bit cumbersome. I also guess it would be difficult to jump between two projects using different versions (e.g. 1.4 vs. 1.5) …

it seems to happen every time I restart intellij since I upgraded to 2021.1, I get

kotlin not configured

and most imports, but not all, marked as red. I tried invalidating cache, reimporting the project from 0 (delete all idea-related files and reimport), but the only thing that helps is removing

rm -f ~/Library/Application\ Support/JetBrains/IntelliJIdea2021.1
rm -rf ~/Library/Caches/JetBrains/IntelliJIdea2021.1/

which is kinda of annoying because it loses some configuration, like vpn tunnels etc

That’s not an issue for me, also running 2021.1 …

it’s weird, because once it happens on a project, it happens on all other projects too. I can open any other project and see the same

kotlin not configured

and dependency not being picked 🤔

That might be more less destructive than deleting your global configuration: • close IntelliJ • delete

.idea/

and

ProjectName.iml

files in my project •

mvn clean

• reopen IntelliJ
