Kotlin 找不到符号 Function1 构建错误

Question

以下是我构建的以下测试方法，使用 Glide 让我的生活更轻松。

    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
        }
    }

它在 JVM 中构建为以下内容

import android.graphics.drawable.Drawable;
import com.bumptech.glide.request.FutureTarget;
import io.vadgroup.cirqle.application.GlideRequest;
import io.vadgroup.cirqle.application.GlideRequests;

    public static final io.vadgroup.cirqle.utilities.GlideUtil INSTANCE = null;

    @org.jetbrains.annotations.Nullable()
    public final java.lang.Object retrieveImage(@org.jetbrains.annotations.NotNull()
    GlideRequests glideRequests, @org.jetbrains.annotations.NotNull()
    java.lang.String uri, @org.jetbrains.annotations.Nullable()
    Function1<GlideRequest<android.graphics.drawable.Drawable>, kotlin.Unit> options, @org.jetbrains.annotations.Nullable()

    kotlin.coroutines.Continuation<? super android.graphics.drawable.Drawable> p4) {
        return null;
    }

    private GlideUtil() {
        super();
    }
}

如果查看上面的 Java 代码，可以看到两个不同的 Function1 对象，一个带有完整的 Kotlin 路径，一个没有。

我怀疑这是由于与我拥有的 Arrow-Core 库发生冲突而发生的，因为它们也有一个 Function1 对象。我完全删除了库，清理了缓存并构建，但是我仍然遇到这个问题。

我目前使用了 Kotlin 版本 1.3.70 和 1.3.71

我将以下项目添加到导入列表的顶部

import kotlin.jvm.functions.*

虽然显示为灰色且似乎未使用，但我能够正确构建项目。
