Kotlin cannot find symbol Function1 build error

Question

Below is the following test method I have built to make my life slightly easier using Glide.

    suspend fun retrieveImage(
        glideRequests: GlideRequests,
        uri: String,
        options: (GlideRequest<Drawable>.() -> Unit)? = null,
        targetCallback: ((FutureTarget<Drawable>) -> Unit)? = null
    ): Drawable? {
        // The GlideRequest we should use to run our request
        val request = glideRequests.load(uri)

        // Apply the options to be used for our request
        options?.invoke(request)

        // Callback for our Future object so that it can be cancelled if necessary
        val drawableFuture = request.submit()
        targetCallback?.invoke(drawableFuture)

        return try {
            withContext(Dispatchers.IO) {
                try {
                    drawableFuture.get()
                } catch (unknownHostException: UnknownHostException) {
                    // Return null, this method was run with no network
                    null
                } catch (interruptionException: InterruptedException) {
                    // Request has been cancelled
                    null
                }
            }
        } catch (cancellationException: CancellationException) {
            // Coroutine has been cancelled
            null
        }
    }

It builds out to be the following for the JVM

        return null;
    }

    private GlideUtil() {
        super();
    }
}

If you look at the above Java code, one can see two different Function1 objects, one with the complete Kotlin path and one without it.

I am suspecting this is happening due to a clash with Arrow-Core library I have since they also have a Function1 object. I completely removed the library, cleaned the cache and build, however, I still run across this problem.

I currently have used both Kotlin versions 1.3.70 and 1.3.71

Answer 1

I added the following item to the top of the import list

import kotlin.jvm.functions.*

Although greyed out and seeming to be unused, I was able to correctly build the project.
