how do i report bugs in the kotlin plugin thats bundled in idea eap versions? it seems to be different than the 1.4.10 plugin but the version is not available in youtrack

I don’t think there’s any special process, if you just include the plugin version from Kotlin page in settings (for me

203-1.4.10-release-IJ5419.1

and IJ version (I usually press the copy icon in

About

screen) it should be plenty. If not, Jetbrains folks will ask for clarification 🙂

Plus you can create an issue in the new project https://youtrack.jetbrains.com/issues/KTIJ and set Affected versions to 2020.3.

What’s the difference between KT and KTIJ projects, when should we use which?

KTIJ is a project for Kotlin Intellij IDEA plugin, so use it for IDE plugin issues (not for compiler, Gradle plugin, etc.). Some time later all issues about IDE plugin will be silently moved from KT to KTIJ (like 20 thousand of them).
