kotlinlang

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`
