Cant publish artifact from to maven repo

I'm trying to publish to OSS nexus from gradle and I'm getting the following error:

Execution failed for task ':uploadArchives'.
> Could not publish configuration 'archives'
> java.io.IOException: Could not PUT 'https://repo1.maven.org/maven2/com/github/bmsantos/cola-gradle-plugin/0.0.3/cola-gradle-plugin-0.0.3.jar'. Received status code 405 from server: Not Allowed

The project in question can be found here:
https://github.com/bmsantos/cola-gradle-plugin

I'm publishing to the same group as and already accepted maven plugin project:
https://github.com/bmsantos/cola-maven-plugin

Do I need to open a new JIRA ticket for it even though I'm publishing under the same group as the maven project?
