I m getting a `Unresolved reference onEach` after updating t

Question

I m getting a `Unresolved reference onEach` after updating to `1 1 2 4` The code compiles and runs fine on `1 1 2 3` Is that a known issue

ilya.gorbunov · Answer

czyzby This can happen if you have API version setting set to 1 0 It constrains you from using new API introduced in 1 1 You can check its value in Kotlin facet of the module

czyzby · Answer

< ilya gorbunov> The thing is the only setting I change is the Kotlin version so if the Gradle or IntelliJ plugins do not default to 1 0 API I just don t see how this is the issue I m also getting some errors during coroutines usage after the update

ilya.gorbunov · Answer

By the way if you use coroutines you should really update to 1 1 2 5 as 4 version has a serious flaw when compiling suspend functions

czyzby · Answer

Yeah I think I ve encountered that issue I had to change `suspendCoroutine` to `suspendCancellableCoroutine` to even make it work I ll try `1 1 2 5` thanks

< ilya gorbunov> I m still getting that error for `onEach` I ve added this to my Gradle setup ``` compileTestKotlin kotlinOptions languageVersion = 1 1 ``` but it still complains about unresolved reference

czyzby · Answer

This must be an IntelliJ issue as it compiles just fine through Gradle

ilya.gorbunov · Answer

Please check what is the API version in Kotlin facet Project Structure gt Modules gt Your module gt Kotlin

czyzby · Answer

< ilya gorbunov> Yes that was the issue What s the correct setup to achieve this My main source modules default to 1 1 API level after Gradle import but test modules are set as 1 0

ilya.gorbunov · Answer

If you didn t set it explicitly in build gradle it should be the same as the version of stdlib namely 1 1 Is there any chance that you get kotlin stdlib 1 0 x for tests

czyzby · Answer

Referenced by some of my dependencies but not explicitly

czyzby · Answer

I include 1 1 as test dependency

ilya.gorbunov · Answer

And does it help

czyzby · Answer

I mean my Gradle script already includes the 1 1 as dependency

czyzby · Answer

And I m still getting this issue

czyzby · Answer

``` testCompile org jetbrains kotlin kotlin stdlib $kotlinVersion force = true ``` `kotlinVersion` is `1 1 2 5` Test modules are still imported with 1 0 kotlin version

czyzby · Answer

< ilya gorbunov> I had to remove all dependencies that used Kotlin 1 0 and reimport the project Gradle refresh was not enough

ilya.gorbunov · Answer

This may be fragile and the problem can happen again when you add them back If you get correct compilation and incorrect diagnostics in IDE related to gradle import please report it as an issue with the build gradle attached

czyzby · Answer

This might have been a weird cache issue I m unable to reproduce it after complete removal of the IntelliJ meta data folder from the project

czyzby · Answer

I ll create an issue if I ever encounter the problem again Thanks
