Developing Gradle plugin as a Maven project

Hello Gradle developers,

I’m looking for a way to build a Gradle plugin using Maven. Background is that our existing projects are all Maven projects but I’m developing Gradle plugin.

I checked the following posts.

But 's latest release is 6.1.1/ 24-Jan-2020 (not 6.5.1).

Is there a different repository and list of Maven artifacts I should use to develop a Gradle plugin in Maven project?
