Kotlin: Supertypes of the following classes cannot be resolved.


I hope this is the right place to ask:

I git clone intellij-community
I open it in IDEA Ultimapte EAP 2023.3
I run the getPlugins.sh
when I build the project I get many Kotlin errors like:

Kotlin: Supertypes of the following classes cannot be resolved. Please make sure you have the required dependencies in the classpath:
   class kotlin.coroutines.EmptyCoroutineContext, unresolved supertypes: java.io.Serializable
   class org.jetbrains.annotations.ApiStatus, unresolved supertypes: java.lang.Object
Adding -Xextended-compiler-checks argument might provide additional information.


somehow it not find the `java.lang.*` or `java.io.*`

maybe someone can point me where to look?



ok - solved it by not using the `jbr-17`

downloaded `Jetbrains Runtime` which results in a name: `jbrsdk-17`

I can build the project without the errors while compilation


Yes I have gone trough the settings. And I can not see where it breaks.  I can not found where I can update/setup a Kotlin SDK.


The Problems Tab is empty

Here are the Setings of jbr-17


But at the Kotlin Setup I miss some paths, but I can not change the home path:


I am fear to delete the Kotlin Entry, because I can not add a different Kotlin. The “Add” menu item don't list a Kotlin option:



The Kotlin Plugin is installed:


Since there are still so many screenshots - here are more to show the settings:


Sorry for the many screenshots - If you need more infos: I am happy to add them :)


Side note: I looked also for the `Jetbrains Runtime` at the list from `asdf list all java` but there is no entry there
