JMH plugin 0.3.0 released, but not available from plugins.gradle.org/m2

I have third party codebase that uses Gradle JMH plugin 0.3.0 (listed on the plugins site since Mar 9).

https://plugins.gradle.org/plugin/me.champeau.gradle.jmh

The problem is that our Artifactory does not see it neither from https://plugins.gradle.org/m2, nor JCenter.

Here it downloads the latest version using the maven-metadata.xml

Does anybody have any idea how to troubleshoot this?

Edit: I got a confirmation from a person in a different location, that they also had to upload the 0.3.0 JAR to their local repo. The problem seems to be in the Gradle Plugins infrastructure.

I have a project where I used it. I am not sure if it is just still caching the dependencies.
I did give 0.2.0 a try on Gradle 2.13 and there were method linkage errors at API level.

So my project works with Gradle 2.5 and 0.3.0. I tested a fresh build on a machine where the jmh plugin had not been used before to be sure. Try this little project. https://github.com/corneil/compare-fp
