If I see a

public const val kotlin_stdlib_jdk8: String = "org.jetbrains.kotlin:kotlin-stdlib-jdk8:_"

in

Libs.kt

, how do I know which version from

version.properties

will be used to replace the

_

? Do I first have to search for

<http://version.org|version.org>_jetbrains_kotlin..kotlin_stdlib_jdk8

and then - if that does not exist - look for variations like

<http://version.org|version.org>_jetbrains_kotlin

or

version.kotlin_stdlib_jdk8

or

version.kotlin

? And do I know which if these will be used if they all exist but have different values?

generally refreshVersions with put

#unused

on entries that are not used by any dependency ./. not sure how realiably it works and ideally for kotlin and other popular dependencies there is rules setup to have them point to a single entry eg.

version.kotlin

In cases that's not obvious, I would do gradlew dependencies --scan and open the dependencies tab to see how it's resolved
