How to add Realm to Android target of Kotlin multiplatform library project? - gradle

Question

I'm trying to add Realm to the android target of my Kotlin multiplatform library but I get this error:
Please initialize at least one Kotlin target in 'library (:library)'.

I can add Realm to any Android project without issues, but when I try to add it to a multiplatform library it doesn't work. Here's my build.gradle.kts:
import org.jetbrains.kotlin.gradle.plugin.mpp.KotlinNativeTarget
plugins {
kotlin("multiplatform")
id("com.android.library")
id("realm-android")
}
kotlin {
val iOSTarget: (String, KotlinNativeTarget.() -> Unit) -> KotlinNativeTarget =
if (System.getenv("SDK_NAME")?.startsWith("iphoneos") == true)
::iosArm64
else
::iosX64
android()
iOSTarget("ios") {
binaries {
}
}
sourceSets {
val commonMain by getting
val commonTest by getting {
dependencies {
implementation(kotlin("test-common"))
implementation(kotlin("test-annotations-common"))
}
}
val androidMain by getting
val androidTest by getting {
dependencies {
implementation(kotlin("test-junit"))
implementation("junit:junit:4.13")
implementation("io.mockk:mockk:1.10.6")
}
}
val iosMain by getting
}
}
val artifactName = "library"
android {
compileSdkVersion(29)
defaultConfig {
minSdkVersion(24)
targetSdkVersion(29)
versionCode = 1
versionName = "1.0"
base.archivesBaseName = "${artifactName}-${versionName}"
}
sourceSets["main"].manifest.srcFile("src/androidMain/AndroidManifest.xml")
}
If I remove the line id("realm-android") it builds fine, but there's no Realm.
