Deploy Gradle on to Maven central. Some of us want to support Gradle users by writing Gradle plugins for our projects but we use Maven as our build system. If the proper dependencies aren’t on central, it becomes much more tedious to write a Gradle plugin.
It’s bad for users (and Gradle adoption in general) because a user that could potentially have performed some task easily via a plugin may instead have to manually wire things together. And, it’s bad for the plugin developer because his/her job is now more tedious, which may cause that developer to drop support for Gradle.
