How to add project reactor dependency in gradle.kts

This is Groovy.

This is Kotlin.

This is looks similar to a plugin definition in Kotlin, but not valid code or what you want.

Just add the version to end of the dependency string in the Kotlin version, just like it is in the Groovy version. Change nothing else other than adding the :1.0.1.RELEASE to the end. Parenthesis and double quotes instead of single quotes are needed for Kotlin.
