Describe the bug

Today, upon build following error occured, for more info check the screenshot below

I want to highlight the line: Could not find org.jetbrains.kotlinx:kotlinx-coroutines-core-common:1.3.2-1.3.60., that's the main reason of cause of build failed, and that was caused by dependency of org.jetbrains.kotlinx:kotlinx-coroutines-io-jvm:0.1.16 which is defined in io.ktor:ktor-server-core:1.2.6 as shown in screenshot below

To Reproduce
Steps to reproduce the behavior:

1. Write the following
   implementation "io.ktor:ktor-server-core:1.2.6"
2. Import using gradle
3. See error

Expected behavior
Expected to resolve the dependency.

Similar issue here. The gradle build fails also on a Kotlin Multi Platform project (Android and iOS), where I use Ktor as HTTP client.

I updated the Android Studio Kotlin plugin to 1.3.60, then updated the project's Kotlin version to the same value. Updated Ktor to version 1.2.6 and Kotlinx serialization to 0.14.0.

The issue seems to be caused by the wrong version number that has been specified for the coroutines library in the Ktor gradle.properties file. It's set to 1.3.2-1.6.0 by this commit 01f940e.

I believe that by setting it just to 1.3.2 it will make the whole thing compile again.
Also, there are some CI jobs that fail on the 1.2.6 tag.

This should be fixed.
