Unresolved reference: main

[shalva97]

hello, decided to do some kotlin native and found this hands-on/Introduction to Kotlin Native/04_AddingInteropToBuild.md

there it says to add some newlines to generate some header files. but I get errors:

e: /home/shalva/intellijProjects/IdeaProjects/untitled/build.gradle.kts:26:22: Unresolved reference: main
e: /home/shalva/intellijProjects/IdeaProjects/untitled/build.gradle.kts:27:13: Unresolved reference: cinterops
