I have a multiplatform project A that uses my own multiplatform library B (i.e. A depends on B in the common source set). I get an unusual error when attempting to build my project and I can't figure out what's causing it exactly: https://pastebin.com/4vKFMLN9 If I remove dependency B from the project, then it builds without issue. I appreciate any help!

Is it possible that Project A includes a JS target, but the Library B does not? Or alternatively, Project A uses JS with IR, while Library B’s JS target is not using IR?

Does B by itself is able to compile? If so, it must be related to what Casey mentioned

Thanks! Yeah Library B can compile. Also both projects have

kotlin.js.compiler=ir

in the gradle.properties and have JS targets

You have to include the target even if empty I guess, in project B

The packages in my repository include the JS, JVM and common also

how is the target declared in

build.gradle

? If a specific JS target is declared in the Gradle file, it will take precedence over the gradle.properties

I see. I'm using Kotlin 1.8.10 and the targets in both projects are declared without a compiler:

js("browser") {
    useCommonJs()
    browser()
    binaries.library()
}

It might also be failing because you gave the JS target a name (

js("browser")

). I’m not certain about this one, but maybe try making sure neither the library nor you application specify a target name, or else that they use the same target name

The name value just defaults to

js

. I'll give that a try regardless although now I'm just getting that latest error

Is saying doesn't find the dependencies of task ...Browser..., which makes me wonder about the 'browser' name

If it helps, here’s the typical setup I use for my JS projects, which has never given me any problems.

// in the library module
plugins {
    kotlin("multiplatform")
}

kotlin {
    explicitApi()

    js(BOTH) {
        browser {}
    }
}

// in the application module
plugins {
    kotlin("multiplatform")
}

kotlin {
     js(IR) {
        browser {}
        binaries.executable()
    }
}

I appreciate it. yeah even though that task is listed in the Gradle tab as available execute. I think it's some dependency that it can't find a value not being set or something
