My approach is: define all versions in constants in object Versions in buildSrc, then configure them from settings.gradle.kts

[Czar]

As an alternative, you could put versions in gradle.properties and configure them from settings.gradle.kts

I am using gradle.properties, but a slightly different way, https://github.com/sureshg/kotlin-scratchpad/blob/master/build.gradle.kts#L8

@Czar I see what you mean, but it's surprising that such a workaround is required for something I would have expected to be simple

[Czar]

yup, I share your pain. You could go to gradle issue tracker and vote on relevant issues, there are a couple.
