guys i'm losing hope with an issue - was happening with a gradle build but i've copied the source code into a new standard Kotlin JVM project and it's still happening. I am using IntelliJ IDEA 2017.2.5 but this issue happened after i tried 2017.3 for a brief moment then moved back

Error:Kotlin: [Internal Error] java.lang.NoClassDefFoundError: Could not initialize class org.jetbrains.kotlin.diagnostics.DiagnosticUtils

already tried everything on this article

This looks like somehow some code cache is corrupted or some classpath elements are incorrect.

how best to destroy all cached files?

new project had only .kt files, no out dir or class files

I think it's my IDE (or combination of latest versions of something), a new project with literally fun main hello world is giving the same result ☹️ 🔫 (and yet other existing projects are ok)

I got a similar error when I didn't have the kotlin-stdlib-jre7 runtime

[jamie-purchase]

thanks but that is in my list of external libraries

8 is there as well 🤔

finally got this sorted 🎉 for some reason I had the path to a different iml file in my .idea/modules.xml file - changed that and it's working fine. Don't know if that is useful to anyone but thought i'd update in case it is
