IDEA reports errors in build.gradle.kts while command line gradle run succeeds

Question

I am using Kotlin DSL with Gradle build tool. My gradle build works well both locally and on jenkins server when run from command line.

However IDEA complains and marks several items red with the following errors:

• Cannot access class 'java.lang.Object'. Check your module classpath for missing or conflicting dependencies
• None of the following functions can be called with the arguments supplied

I have tried all 3 options in project settings: - Use default gradle wrapper - Use gradle 'wrapper' task configuration - Use local gradle distribuition

Result if pretty same

QUESTION: is something wrong in config, or is there a fix or workaround for that?

UPD: @tweitzel you are right, it was incorrect SDK setting, thanks!

Answer 1

in my case I had set a jdk as File->Project Structure... -> Project->Project SDK

instead of setting the Kotlin SDK

after setting Kotlin SDK as Project SDK my build.gradle.kts errors disappeared
