kotlinlang #multiplatform

I'm kind of stuck on another Kotlin Gradle question. I am trying to create a Gradle configuration for a jvm classpath, but I'm getting an AmbiguousConfigurationSelectionException. In java this works:

configurations.create("myConfig") {
	dependencies.apply {
		add(project.dependencies.create("com.example:foo:version"))
	}
}

// In the task:
getExecActionFactory().newJavaExecAction().apply {
	classpath = project.configurations.getByName("myConfig")
}

But I don't know how to do the equivalent if the dependency is a kotlin multi-platform library. I get an exception such as:

Caused by: org.gradle.internal.component.AmbiguousConfigurationSelectionException: Cannot choose between the following variants of com.example:foo:version:
  - js-api
  - js-runtime
  - jvm-api
  - jvm-runtime
  - metadata-api

What do i need to do, to "import kotlin.system.measureTimeMillis" in commons module, so it don't complain about unresolved reference?

Has anyone using 1.3.50 and the

allTests

task been able to get test results as JUnit-like XML files? I'm only getting the HTML report page in

reports

and

binary

test-results

when using JVM and the (new) built-in JS test setup, which makes CI a bit less easy to use

Hello, trying to upodate my project to 1.3.50, I get the following errors:

. The abi versions don't match. Expected '[14]', found '9'
w: The compiler versions don't match either. Expected '[]', found '1.3-release-10826'

I thought using the last version of each library would be OK:

kotlin_version=1.3.50
ktor_version=1.2.3
kotlinx_serialization_version=0.12.0
kotlinx_coroutines_version=1.3.0

Any idea what the right versions should be?

I have a class in my

commonMain

module and 2 extension functions in my

androidMain

and

jvmMain

modules which happen to have the same prototype. IntelliJ is complaining in the

androidMain

module when I use this extension that it doesn’t know which one to use because it’s defined twice. The problem doesn’t occur in

jvmMain

and everything compiles fine, it’s IntelliJ being lost I suppose

In a Gradle project with many modules, some MPP and some JVM only, how can I add a dependency in a JVM module to the JVM part of a MPP module? This produces an error:

implementation(project(":path:to:mpp-module"))

WARNING: Ignoring dependency of module 'mpp-module' on module 'jvm-module'. Java modules cannot depend on Android modules

Anybody publishing a library as a cocoapod? Wondering if there are any obvious issues. I’m aware that you can’t include multiple. This is for a client that wants to distribute their library to developers for use in native apps. Most would just be importing the framework on iOS. If somebody wanted to use it as a multiplatform library, that would be available as well.

Has anyone explored, or seen demos, of a MP project with a JS frontend? Here I mean the kotlinjs output would be imported into a js project, not a kotlinjs project. All the samples I have seen are using kotlinjs. This type of setup would be useful for integrating into existing JS projects

What's the best option for controlling shared mutable state in common code? I have a cache that can be accessed and updated by multiple coroutines (on JVM, anyway). Actors are unavailable on native, so should I go with a Mutex approach, or make the cache an AtomicReference?

Anyone writing multiplatform/common classes with Dagger’s

@Inject

on it? Since it’s a JVM-only type, so I tried to create my own

Inject

with

@OptionalExpectation

on it, but can’t seem to figure out the

for it.

russhwolf

09/01/2019, 8:22 PM

The biggest benefit is that Reaktive already exists, so it saves you the work of designing and maintaining your own API. RxJava and RxSwift are not identical and I suspect it’ll be pretty difficult to create a clean expect/actual API on top of them.

09/01/2019, 8:29 PM

RxSwift usage is going to be difficult, if not impossible, inside kotlin until Swift interop comes to native

saket

09/01/2019, 8:34 PM

Oh! I assumed they both align with the same reactive extensions standards. I looked into Reaktive, but I feel slightly uncomfortable that it re-implements all operators. RxJava and RxSwift are well battle tested whereas Reaktive is not.

basher

09/01/2019, 8:46 PM

It has nothing to do with the Rx standards. K/N has direct interop with Obj-C, not Swift. Going the other way, it annotates it's header to make the classes feel nice from Swift. But for direct interop, RxSwift isn't usable from Obj-C (90% sure on that), so K/N won't be able to see it (assuming you wanted to use it in Kotlin). You'd have to add some bridging somewhere (possibly Obj-C)
