Ok, we’ve tried to create a new Kotlin project from scratch and just call intArrayOf() in main() function on that machine, and we’ve got the same error 😞

try to reinstall the kotlin intellij plugin

Could you find which jar file from compile classpath on that machine сontains

kotlin/KotlinPackage.class

?

@ilya.gorbunov Ok, I’ll try. But why do you think that there is this class in some JAR?

Otherwise there's no reason that compiler could generate a reference to it.

Ok, we’ve performed

find . -name "*.jar" | xargs grep "KotlinPackage.class"

command for IDEA application directory, project root directory and ~/.gradle/caches and have got empty results. I don’t see any JARs outside of that directories in the classpath according to build.log I sent above…

At this point it's better to create an issue, because I'm out of ideas
