I have a multiproject gradle setup with Kotlin DSL. In my master build.gradle.kts I have:

val someVersion: String by extra("1.2.3")

However, in childproj/build.gradle.kts:

val someVersion: String by extra

does not work, saying “Cannot get non-null extra property ‘someVersion’”

What’s the appropriate way to do variable inheritance?

extra is scoped. In the child project you can do either of these:
val someVersion: String by project (project delegate inherits properties from parent project, including extra)
or direct access if you want to prevent a clash with something like `gradle.properties`:
val someVersion: String by rootProject.extra

If you don't need the dynamic initialization extra("1.2.3") any properties you put in your gradle.properties will be available to all projects
gradle.properties
someVersion=1.2.3
