How do you run your apps when developing? From command line or Gradle tool window in IDE? I’m having an issue with the latter that it uses a wrong JDK to run it, ending up in error:

MainKt has been compiled by a more recent version of the Java Runtime (class file version 55.0), this version of the Java Runtime only recognizes class file versions up to 52.0

./gradlew run

from command line works fine Where do I configure JDK for the IDE? (IntelliJ IDEA CE 2020.3.1)

File/Project Structure

I see the correct one there (the error is with

jdk1.8.0_192.jdk

)

That's right. You need JDK11+

Yeah, but I don’t see that jdk set anywhere, when I do

java -version

in terminal I get

openjdk version "15.0.2" 2021-01-19

there is a separate setting for gradle vm. in preferences

That was it, thanks 👍
