Add dependencies

kotlin {
    sourceSets {
        val commonMain by getting {
            dependencies {
                implementation("com.example:my-library:1.0")
            }
    }
}

Alternatively, you can set dependencies at the top level.

A dependency on a standard library (stdlib) in each source set is added automatically. The version of the standard library is the same as the version of the kotlin-multiplatform plugin.

The kotlin.test API is available for multiplatform tests. When you , the Project Wizard automatically adds test dependencies to common and platform-specific source sets.

If you use a kotlinx library and need a platform-specific dependency, you can use platform-specific variants of libraries with suffixes such as -jvm or -js, for example, kotlinx-coroutines-core-jvm. You can also use the library base artifact name instead – kotlinx-coroutines-core.

kotlin {
    sourceSets {
        val jvmMain by getting {
            dependencies {
                implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core-jvm:1.4.2")
            }
        }
}

If you use a multiplatform library and need to depend on the shared code, set the dependency only once in the shared source set. Use the library base artifact name, such as kotlinx-coroutines-core or ktor-client-core.

kotlin {
    sourceSets {
        val commonMain by getting {
            dependencies {
                implementation("org.jetbrains.kotlinx:kotlinx-coroutines-core:1.4.2")
            }
        }
    }
