Hey @Goooler and thanks for your contribution!
The renaming here does create a breaking change for Kotlin users, and it's important to note that we didn't make this change with that intention in mind. Do you think there's a genuine reason to justify this modification?

I believe we should follow the Gradle guidance to use a standard extension(including honoring the standard extension name), we can note this point in changelog and recommend users to use artifactory block to configure properties like the Groovy did.
