Question

Any idea why I need to specify the version explicitely if I depend on `kotlin stdlib jdk8` but not for plain `kotlin stdlib` `implementation org jetbrains kotlin kotlin stdlib ` works but `implementation org jetbrains kotlin kotlin stdlib jdk8 ` doesn t

How are you specifying the version otherwise via the plugin or using the BOM

mbonnin · Answer

What is BOM

mbonnin · Answer

I have `classpath org jetbrains kotlin kotlin gradle plugin 1 3 41 ` in my root build gradle kts I guess this is where the version comes from

octylFractal · Answer

<https mvnrepository com artifact org jetbrains kotlin kotlin bom 1 3 41> Bill Of Materials specifies version for all artifacts Gradle supports this by doing `implementation platform org jetbrains kotlin kotlin bom 1 3 41 `

mbonnin · Answer

Ah nope I m not using that

octylFractal · Answer

I think if you re using the plugin and Kotlin DSL the preferred way to get the version automatically is to do `implementation kotlin stdlib jdk8 `

mbonnin · Answer

Yep that s the thing that doesn t work

mbonnin · Answer

```ERROR Failed to resolve org jetbrains kotlin kotlin stdlib jdk8 Affected Modules app ```

mbonnin · Answer

The `kotlin ` shorthand just prepends org jetbrains kotlin it does not add version

< mbonnin> are you using Kotlin JVM plugin or Kotlin Android plugin

mbonnin · Answer

`id kotlin android `

mbonnin · Answer

Kotlin Android it is

Sergey Chelombitko · Answer

Kotlin Android plugin doesn t allow to omit version of `kotlin stdlib ` until 1 3 50

Sergey Chelombitko · Answer

or any other libraries in `org jetbrains kotlin` group

mbonnin · Answer

The this is it allows me to omit the version of `kotlin stdlib`

Sergey Chelombitko · Answer

That s coincidence because there was simply no such feature in Kotlin Android plugin I know this because I ported it from JVM plugin to Android plugin

octylFractal · Answer

`kotlin stdlib` may be an transitive dependency of another `kotlin android` library and therefore doesn t need a version I don t recall exactly how gradle handles that case

mbonnin · Answer

Ah yes good catch It seems the kotlin android extensions plugin pulls `org jetbrains kotlin kotlin android extensions runtime 1 3 41` and that in turns pull `kotlin stdlib`

mbonnin · Answer

So I can just remove `implementation org jetbrains kotlin kotlin stdlib ` but if I need jdk8 I have to specify the version It all makes sense thanks
