I am trying to run the tests of the kotlin code provided from here : https://github.com/ligi/ipfs-api-kotlin with gradlew
I got the error listed below. Could someone tell me what this error means ?

Fixed this error changing Java SDK in my project from 14 to 11 and my tests started working fine.
Solution: IntellijIDEA: File > Project Structure > Project Tab > SDK adopt-opendjdk-11 (in my case for Ubuntu).
Oh! Make sure Gradle Settings are also using the same JVM!
Hope that helps someone out there.
