Calling setCanBeResolved(true) has been deprecated. This will fail with an error in Gradle 9.0

When setting an existing build-configuration to resolvable, eg. in order to generate :javadocs ...

configurations.getByName("implementation").isCanBeResolved = true

This leads to the following deprecation warning:

Calling setCanBeResolved(true) on configuration ':implementation' has been deprecated.

This will fail with an error in Gradle 9.0.

This configuration's role was set upon creation and its usage should not be changed.

Consult the upgrading guide for further information:
https://docs.gradle.org/8.14.2/userguide/upgrading_version_8.html#configurations_allowed_usage

When following the given link to the documentation, it doesn't really tell what to do about it.
So how to clone configuration implementation and set property isCanBeResolved = true?
The issue is rather related to Gradle than Android, but may well happen in an Android project.

In Kotlin DSL, this means by configurations.creating combined with extendsFrom().

val implCls: Configuration by configurations.creating {
    extendsFrom(configurations.getByName("implementation"))
    isCanBeResolved = true
}

Obviously, one also has refer to implCls instead of implementation then.

classpath += implCls.asFileTree.filter {it.extension == "jar"}

Now there's also two specific Configuration sub-classes (incubating):

• ResolvableConfiguration
• ConsumableConfiguration
