I am trying to play around with value and inline classes on the kotlin playground but it has an unresolved reference to the JvmInline annotation, and specifically importing kotlin.jvm.JvmInline leads to a This declaration is only available since Kotlin 1.5 and cannot be used with the specified API version 1.4 is there a specific way to get this to work in the playground currently?

see, thats for gradle...im trying to get it to work in the kotlin playground

[ephemient]

https://kotlinlang.org/docs/reference/whatsnew1430.html

To try the preview version of inline classes, add the compiler option -Xinline-classes or -language-version 1.5.

[ephemient]

maybe file an issue on https://github.com/JetBrains/kotlin-playground if you want to see it enabled there

[WukongRework.exe]

would that be in the program arguments in the settings tab?

[ephemient]

else you can run your own

[ephemient]

no, program args vs compiler args

[WukongRework.exe]

yea i was planning on running in intellij once i got the chance but currently im on mobile so i dont have access to intellij currently 😞

[WukongRework.exe]

is there a way to change compiler args in the kotlin playground?

[ephemient]

aside from updating the kotlin-playground itself, no

[WukongRework.exe]

oh ok

[ilya.gorbunov]

Yes, new language features require enabling language version 1.5 with a compiler argument, which is not specified for compiler used in Kotlin playground.

i guess i will wait for the website to get updated then thanks

[ilya.gorbunov]

I'll file an issue for specifying it.

[WukongRework.exe]

ah thanks, any idea when it will be enabled?

[WukongRework.exe]

oh ok thank you!
