I’ve got an issue and I have no idea where it could come from. I’ve got a top level public extension function defined in the common part of a multiplatform project like this:

fun HttpRequestBuilder.useAuthentication() { ... }

HttpRequestBuilder

is from Ktor client. I’m trying to use it in another project which has the above one as a dependency:

private suspend fun postUploadFile(successUrl: String): Unit =
        <http://http.post|http.post>(successUrl) {
            useAuthentication()
        }

http

is a Ktor

HttpClient

. IntelliJ IDEA sees the extension, imported it alone without me doing anything, everything works inside IntelliJ. Then I tried to build.

> Task :compileDebugKotlinAndroid FAILED
e: <myFile>.kt: (9, 37): Unresolved reference: useAuthentication

The reference position is in the imports. What could cause that? I’m posting here because I have no idea where to start. It only seem to happen for this top level extension right now. Maybe it’s a Gradle metadata issue? But then why would IntelliJ see it?

#ktor probably?

Did you read my post?

Yes?

This is obviously not a ktor issue

You're writing an extension fun for ktor clients, you try to use the same within a ktor request…

You’re not helping

sounds like an issue with resolving your common module. I have this happen a lot if I am not using gradle's composite builds, but instead pushing to mavenLocal.

In this case the dependency is in an artifactory server. I'll try to clean everything and rebuild to see if that works

is the IDE and compiler both using the same version of kotlin? Have you tried setting ktor common dependencies to API instead of implementation (if they're implementation right now)

I already found that it’s not related to Ktor, but I’ll change

implementation

to

api

for my parent lib in the child lib build file and see if it does anything

Do you import

useAuthentication

?

Yes, the IDE imported it. The IDE sees it. There’s no error in IntelliJ, but I can’t build
