Cannot choose between the following variants of com.squareup.okio:okio:2.3.0

I just upgraded from okio:2.2.2 to okio:2.3.0 and don’t know how to tell gradle which artifact to use 🤔 Is there a documentation how to declare okio for non kotlin-multiplatform projects?

Could not determine the dependencies of task ':main:kaptDebugKotlin'.

If you go to start.spring.io and configure a project with Gradle Project; Kotlin; Spring Boot 2.3.0; Packaging Jar; Java 11 download the project, unzip it and add implementation("com.squareup.okio:okio:2.6.0") to build.gradle.kts (dependencies) This error will show up when running ./gradlew clean build

* What went wrong:
Execution failed for task ':bootJar'.
> Could not resolve all files for configuration ':productionRuntimeClasspath'.
   > Could not resolve com.squareup.okio:okio:2.6.0.

Removing the line with kotlin("kapt") version "1.3.72"doesn’t change anything. Generating a project for SpringBoot version 2.2.7.RELEASE doesn’t show this error.

In the end I was able to solve it with this workaround based on the solution described here: https://github.com/google/protobuf-gradle-plugin/issues/391#issuecomment-609958243

I added this to the end of my build.gradle.kts

configurations.forEach {
  if (it.name.contains("productionRuntimeClasspath")) {
    it.attributes.attribute(Usage.USAGE_ATTRIBUTE, objects.named(Usage::class.java, "java-runtime"))
  }
}

I suspect that the Kotlin Gradle plugin should be doing something similar internally, that should hopefully get fixed in subsequent releases. The workaround looks good, I’m gonna keep this issue open in case somebody else experiences it.
