hi, after kotlin 1.9 kts within source roots are not compiled. I tried to apply

-Xallow-any-scripts-in-source-roots

to freeCompilerArgs but with no success. What is the correct way to get back old behaviour?

Could you please provide some more details? K2 compiler supports scripting in general, but it's not stable yet. Therefore we'll appreciate the bug reports.

@ilya.chernikov https://github.com/bukajsytlos/kotlin-script-source-root-demo with k2=true main.changelog.kts is not within compiled classes in build folder

Could you please try it with additional compiler arg

-Xuse-fir-lt=false

?

it creates class but this is in console

Ok, I see. Most likely, this is an untested scenario - compiling kotlin scripts with K2 in a source root. I need to investigate it a bit more. I'd appreciate it very much if you'd create an issue in the YT and attach there the link to your project and the stacktrace above.
