I have tried to use KTor for a KMM (Kotlin Multiplatform Mobile) project but the shared module (commonMain) doesn't see the ktor library after I've added it as a dependency ... Anyone had success with using KMM with KTor in the shared module or is it not ready yet?

Ktor client works just fine.
What dependency did you add and how?

[jdamcd]

there are some good example projects out there, maybe compare your dependency setup with e.g. https://github.com/joreilly/PeopleInSpace

My bad, I should have provided more details.

I have followed this guide: https://ktor.io/docs/http-client-multiplatform.html

My shared gradle build file looks like that:

import org.jetbrains.kotlin.gradle.plugin.mpp.KotlinNativeTarget

val ktorVersion = "1.5.0"

plugins {
    kotlin("multiplatform")
    id("com.android.library")
}

kotlin {
    android()
    ios {
        binaries {
            framework {
                baseName = "shared"
            }
        }
    }
    sourceSets {
        val commonMain by getting {
            dependencies {
                implementation("io.ktor:ktor-client-core:$ktorVersion")
            }
        }
        val commonTest by getting {
            dependencies {
                implementation(kotlin("test-common"))
                implementation(kotlin("test-annotations-common"))
            }
        }
        val androidMain by getting {
            dependencies {
                implementation("com.google.android.material:material:1.2.1")
            }
        }
        val androidTest by getting {
            dependencies {
                implementation(kotlin("test-junit"))
                implementation("junit:junit:4.13")
            }
        }
        val iosMain by getting
        val iosTest by getting
    }
}

android {
    compileSdkVersion(30)
    sourceSets["main"].manifest.srcFile("src/androidMain/AndroidManifest.xml")
    defaultConfig {
        minSdkVersion(24)
        targetSdkVersion(30)
    }
    buildToolsVersion = "30.0.3"
}

val packForXcode by tasks.creating(Sync::class) {
    group = "build"
    val mode = System.getenv("CONFIGURATION") ?: "DEBUG"
    val sdkName = System.getenv("SDK_NAME") ?: "iphonesimulator"
    val targetName = "ios" + if (sdkName.startsWith("iphoneos")) "Arm64" else "X64"
    val framework =
        kotlin.targets.getByName<KotlinNativeTarget>(targetName).binaries.getFramework(mode)
    inputs.property("mode", mode)
    dependsOn(framework.linkTask)
    val targetDir = File(buildDir, "xcode-frameworks")
    from({ framework.outputDirectory })
    into(targetDir)
}

tasks.getByName("build").dependsOn(packForXcode)

My expectation was that adding:

val commonMain by getting {
            dependencies {
                implementation("io.ktor:ktor-client-core:$ktorVersion")
            }
        }

will allow me to import io.ktor.etc in src/commonMain/kotlin/… files. But no such luck

What gradle version do you use? Looks like it doesn't pick up gradle metadata for some reason

[Krotick]

Thanks for looking into it. The gradle version is Gradle 6.8-rc-4
