Hello guys, I have a question, I created project with standart Android Studio KMM plugin.
And then I added also my backend module into project as jvm target but surprisingly backend Module is not seeing commonJvm rather it sees commonAndroid expected values. Also I can not reach the class in commonMain from backend module.

Did anyone had similar issue ?

You can see the gradle.kts files in thread

You can't have Android and JVM applications in the same project yet. I think there's an open issue for that.

[Mustafa Ozhan]

Ohh really 🤔 but I have seen some repos with both JVM and Android.
Like
https://github.com/jarroyoesp/KotlinMultiPlatform
https://github.com/joreilly/PeopleInSpace

[Ali Albaali]

There are, but I don't think they work TBH, but I could be wrong.

[Mustafa Ozhan]

PeopleInSpace, works on my local

[Ali Albaali]

Are you sure? Cuz as I remember on one of my projects, i tried it and it didn't work, I came across this tho https://stackoverflow.com/questions/59479020/how-to-share-java-code-between-android-and-jvm-targets-with-kotlin-multiplatfor but didn't work either.

[Mustafa Ozhan]

Yes, but it is weird, i add some classes in PeopleInSpace it behaved like how it is for me

On the other PeopleInSpaceApi (located in commonMain)
https://github.com/joreilly/PeopleInSpace/blob/master/common/src/commonMain/kotlin/com/surrus/common/remote/PeopleInSpaceApi.kt
can be reachable from backend module should be some trick to achieve this, I created a new class in same file couldn’t reach it

[sergiocarabantes]

Hi guys, i have exactly the same issue. I don't understand why in PeopleInSpace project is working... hmm 🤔

[Mustafa Ozhan]

@John O'Reilly maybe you can explain us since you are the repository owner 🙂

[John O'Reilly]

If you can fork PeopleInSpace and repo issue you're seeing I'll try and get some time later to take a look

[Mustafa Ozhan]

Hey, No we do not see any issue your repo works fine 🙂 and we wonder how you managed to access commonMain classes in backend module. Is there any trick for that ?

It seems we are having issues and backend module only sees androidMain for some reason.

[John O'Reilly]

"i add some classes in PeopleInSpace it behaved like how it is for me"

was referring to this....sounded like you were able to reproduce same issue using PeopleInSpace (by adding some class?)...but I might have misunderstood?

[John O'Reilly]

I guess main thing is that following is in backend module gradle file but presume you probably something like that in your project as well?

implementation(project(":common"))

[Mustafa Ozhan]

yeap i have

implementation(project(":common"))

but something is still missing,
On the other hand I download your repo,
you have PeopleInSpaceApi class in commonMain and you can use it in Server.kt, tested working, I created TestCommon class in same file couldn’t access it in Server.kt
So I started to wonder if there is any extra step to make commonMain files visible in backend module

[John O'Reilly]

I don't believe I did anything else specifically to allow that (though perhaps did so inadvertently 🙂 )

[sergiocarabantes]

Thanks John. Which version of AS are you using? I tried stable, alpha, beta and I have the same issue in my personal project like @Mustafa Ozhan Still wondering why it only works in your project only 🙂

[John O'Reilly]

I'm using 4.2 Canary 13 at the moment (have to use that for Jetpack Compose right now)

[Mustafa Ozhan]

To clarify the weird problem please check the video 🙂 I hope I demonstrated it good 🙂

Meanwhile, I downloaded 4.2 Canary 13 and tested results are same

[John O'Reilly]

so, I tried to replicate that here....like you it didn't show TestCommonMain as option as I was typing it.....but....was able to add as import and could resolve it then

import com.surrus.common.TestCommonMain

[John O'Reilly]

so perhaps some issue with AS

[Mustafa Ozhan]

Interesting 😕 manually not working for me either, will try to clean Android Studio compeletelly and use latest version

[sergiocarabantes]

@Mustafa Ozhan Finally I got it. Clean everything. Remove .gradle, .idea, build folders for every single module. After that, invalidate caches and restart. Now I can have access to 'commonMain' 🙂

[sergiocarabantes]

I just did this using 4.2 Canary 13

[Mustafa Ozhan]

Okay finally I make it work too 🙂 thanks a lot guys 🙂
