how can I run kotlin in any free IDEs? the reason i dont use intellij because its not free

[Joffrey]

As a side note, IntelliJ community edition is free

[Joffrey]

You seem to be using a third party library. Did you declare this dependency in your build tool's configuration (build.gradle.kts)?

oh yes, i just scrolled down & found the community edition. thanks
