You can use the same ext trick you used in Groovy, just with Kotlin syntax.
That is to initially define the variable, you use extra explicitly, so val foo by extra("bar"), in the root project
and just get it from the subproject to use it, so val foo: String by project

But the question is whether you should do it.
In almost all cases using ext or extra is a work-around and one should feel dirty when using it.
Most often there is a better way, like for example adding a properly typed extension to the project instead.
