03/30/2021, 2:48 PMHello everyone!
I am trying to split my kmp ‘shared’ module into smaller modules and I am stuck. Inside the ‘shared’ module I’ve created a new multiplatform module (I tried with java/kotlin library too, but I was not able to import it).
I have included it in “commonMain” as “api(project(“sharedcore”))” and it syncs correctly, but when I try to use a class which is in the shared:core module (from the shared module) it cannot be reached.
I have also tried to look into the kmpp-template from moko but as most of the gradle setup is done by their library I was not able to understand how to set it up.
I attach the gradle files in a thread.
Any hint or reference to a guide will be much appreciated! Thank you!

}Also, I have noticed that in the moko kmpp-template they export libraries. Is that necessary for the library to be consumed from the ‘shared’ module? And is it necessary to have access to some classes from the android/ios code?

If I understand, you should be able with that setup to use the core classes inside shared module

03/30/2021, 4:10 PMI would try to add those libraries manually
if it works, then you know what is the problem
indeed, project A can't use project B tests dependencies
so that should be the problem

I’ve noticed something else. The color highlighting doesn’t work on shared:core, and if I try to add a file Kotlin does not show up as an option. There seems to be something wrong with the kotlin setup
Ok I’ve figured it out. I had to remove
