Hello,
I would like to use K2 compiler and I am solving issue: https://youtrack.jetbrains.com/issue/KT-55177 (Deprecate declaration of expect and actual counterparts of same class in one module)
I need to add -Xcommon-sources CLI flag, but documentation is not clear.
Can you help me with example solution for this problem?
Thanks

The most recommended way is to setup KMP project structure using kotlin-multiplatform gradle plugin
If you want to experiment with some stuff and run the compiler manually, you can list sources from free args also in -Xcommon-sources flag
But generally I don't recommend it because:
1. This flag will be deprecated soon in favour of -Xfragments cli flag
2. It's really hard to manage KMP flags manually

I have expect class Driver in commonMain and actual class Driver in androidMain. How to setup parameter -Xcommon-sources for successful build?

[dmitriy.novozhilov]

-Xcommon-sources=/path/to/file/with/expect/Driver

At the same time both files (with expect and actual classes) should be passed to kotlinc as free arguments

And solution via gradle plugin?

You just setup your project as KMP project (e.g. like in this guide), then call ./gradlew compileKotlinAndroidMain (or anything else) and it just works
