Hi, I'm trying to add a

common

module as a dependency to another

common

module but I'm not able to get it working. I tried with

implementation

,

api

and

compileOnly

but any of them give me a successful

build

. Could anyone helps me?

so you just have 2 separate source sets in the same build.gradle?

Multi-level common code is currently under heavy development https://youtrack.jetbrains.com/issue/KT-27801

I have 2 modules on the same project each of them with its own

build.gradle

Then just adding an

api

or

implementation

dependency on another project to the

commonMain

source set should work: you will be able to use the declarations from the other project's

commonMain

, and also platform-specific declarations in the appropriate platform-specific sources of the depending project.

kotlin {
    sourceSets {
        val commonMain by getting {
            dependencies {
                implementation(project(":foo"))
            }
        }
    }
}

If it doesn't work for you, could you please provide more details about the project structure?

it doesn't, wait a sec I'll share the project

Also, as Alex Gherschon noted above, we are working to improve the behavior of such dependencies with custom source set hierarchies, which are now not fully supported yet, but the simple case with just

commonMain

and platform-specific sources should work.

This is the repo https://github.com/AdrianRaFo/common-dep-issue

First, the

kotlin-platform-common

plugin is a part of Kotlin 1.2.x MPP tooling that is now becoming obsolete (no active development, and we have plans to deprecate it). Also, the current architecture of multiplatform projects requires that all expect declarations are provided with actual implementations within the same module, and no actual implementations can be added by a library consumer.

Sorry I fixed the sample for a more clear sample of my issue
