Same problem here. Is there a workaround until a proper fix is released?

[apatrida]

I'll check Keplin and the Jupyter-Kotlin to see where the breaking is, and where that reference is coming from.

[davidsands]

Me too. If it's any help, Dmitry-Borodin wrote on Jan. 5:

I wrote the test for Keplin, and logger is there. But I don't have it at runtime while using it as a library for some reason...

[davidsands]

Could it be jetbrains moved the intellij.openapi.diagnostic.Logger class?

In the keplin source:
keplin-core/src/main/kotlin/uy/kohesive/keplin/kotlin/script/resolver/AnnotationTriggeredScriptDefinition.kt
...
import org.jetbrains.kotlin.com.intellij.openapi.diagnostic.Logger
...

Exception in thread "main" java.lang.NoClassDefFoundError:
org/jetbrains/kotlin/com/intellij/openapi/diagnostic/Logger

Current location of the class:
found in kotlin-compiler-1.2.21.jar:
com/intellij/openapi/diagnostic/Logger.class

I don't have enough experience to know how to fix this, if it is indeed the problem.

[apatrida]

I see the mismatch in compiler libraries, so working to fix that now.

[apatrida]

Can someone check master now and see if you still have the issue?

[davidsands]

It's fixed here. Muchas gracias!

[holgerbrandl]

Same here. Herzlichen Dank!

[eggcaker]

works. 👍
