though the kspKotlin task works and generates the source files, when i disable the ksp plugin and remove the ksp(...) dependency the application starts fine

thx, bernd

It looks like that this was called from kotlinc command line (in contrast to called within Gradle). I.e., called via kotlinc -Xplugin=<path-to-ksp-jar> from shell. The artifact for Gradle cannot be used in command line.

We'll publish the artifacts to be used with kotlinc command line later. #411

I've been getting this exact error with KSP only when running tests or mains from IntelliJ using IntelliJ runner? I've tried various kotlin versions and on latest and greatest at this point. Any idea hat could be causing this and how to troubleshoot it?
