Hi. Not sure if multiplatform channel is the right place and even not sure if that is possible. So, I am generating Kotlin response/request data classes used by Ktor. I'd like to keep them separate from common module. Created another module and included api(project(":generatedapi")) it as a dependency to common module. It compiles and builds successfully but when I publish the project as a library, those generated classes are not included so clients which are using multiplatform library cannot access them. Does anybody tried to achive something similar like this or maybe know a way how to expose dependency classes to clients? Thanks.

Either publish that module as well or add it as implementation

[rsetkus]

@Big Chungus when say 'add it as implementation' you mean dump generated classes into common module?

[Big Chungus]

No, i mean replace api to implementation on that dependency snippet you've sent

[rsetkus]

Cannot access class 'xx.yy.DataClass. Check your module classpath for missing or conflicting dependencies

[Big Chungus]

Is that from the lib consumer?

[rsetkus]

Getting this error on client side on attempt to use a class

[rsetkus]

Yeah

[Big Chungus]

In that case you need to make your lib fat-ish jar that includes that module explicitly

[Big Chungus]

Here's an example

[Big Chungus]

And here

[Big Chungus]

Second example is better suited to you. First one is embedded kotlin js as webjar

[rsetkus]

Yeah, maybe the second example is something I am looking for. Will give a try. Ačiū

[rsetkus]

Not sure why but jar task is not found in my main multiplatform module. Instead used jvmJar and that worked fine.

That works for Android, but I suppose I'd get the same issue for iOS. 🤔

[Big Chungus]

You will. In this case why not just publish your internal module?

[rsetkus]

But client/consumer would need to include (specify in dependencies) both libraries, wouldn't it?

[Big Chungus]

Nope

[Big Chungus]

Gradle/maven would download that internal dependency as transitive

[rsetkus]

This is the thing. I published the other module too. Also, I can see that on client/consumer app's dependency tree, library is pulled as transitive dependency but still on client/consumer side I am getting error

Cannot access class XXX Check your module classpath for missing or conflicting dependencies

[Big Chungus]

Is your class public?

[rsetkus]

Yes, correct. It is public.

[Big Chungus]

Then I'm out of ideas. Can't help you more without seeing the actual code :/

[rsetkus]

No worries. I'll try to make SSCCE (a Simple, Self-Contained, Correct (Compilable), Example) and publish it on github, for instance.

[Big Chungus]

Tbh, I'm only interested in your gradlefiles and class signature. So if you could remove all your source code and publish that I could have a proper look

[rsetkus]

Made gist files first. Let me know if you more context.

[Big Chungus]

Can you make a proper git repo replicating your project structure? Will have a look at that first thing tomorrow

[rsetkus]

Yeah, sure. No problem. Will post a link here.

[Big Chungus]

Hold on. I see you now have everything as implementation. Can you try changing all dependencies to api and see if that works?

[rsetkus]

Yeah, that worked. 🎉 Changed absolutely all implementation to api . I used api before but only for the other internal module and that didn't work.

[Big Chungus]

Great! Api didn't work before because you weren't publishing the internal module

[Big Chungus]

Api dependencies - transitive dependencies that gradle will download for the consumer

Implementation dependencies - provided dependencies that gradle expects to already be on the classpath

[rsetkus]

I see! Yeah, probably you're right. then I used api before, I didn't publish it at that time.

Thanks a lot! I owe a 🍺 🙂
