Consume Gradle artifacts in Maven build

I am contributing to a project built using Maven. Part of this project is a Gradle plugin. Importing this monstrosity into IDE (IJ) does not work well for the Gradle plugin module because the pom does not define dependencies on Gradle artifacts (so org.gradle.api.Project, e.g., is not available).

Are there Maven coordinates (Maven Central, JCenter, etc) that I can use to pull Gradle artifacts into the Maven build?

I’ve searched under https://mvnrepository.com/artifact/org.gradle but none of those stand out as the right artifact(s). Not to mention that the versions seem older (6.1). https://mvnrepository.com/artifact/org.gradle/gradle-core-api seems like the right one, but the latest version is 6.1.1

Thanks!
