Any idea, how to troubleshoot:

Error: Could not find or load main class org.jetbrains.kotlin.cli.jvm.K2JVMCompiler
Caused by: java.lang.ClassNotFoundException: org.jetbrains.kotlin.cli.jvm.K2JVMCompiler

1.5.21 gradle plugin, tried different SDKs, upgrading plugin to 1.5.30-M1, downgrading to 1.5.20, 1.5.10. Cleaning project, removing whole $HOME/.gradle directory.
This error relates to submodule of multi-project project. Modules use either jvm or mpp plugin.

When running with --debug, we get a little interesting output:
