It's a bug. Thank you for reporting! @epeee, can you take a look at this? Upstream bug in Shipkit: https://github.com/mockito/shipkit/issues/741 @mockitoguy sorry, I was busy yesterday. 
I can have a look at the upstream bug in shipkit tomorrow. Not sure if it is related but the `2.20.1` is available in JCenter but not in Maven Central. There is some delay. Bintray log shows that the sync was successful. Let's wait until the end of the day.

Thanks for checking! OSS repo has the right artifacts so I think it's just a delay before it's searchable in central. Proof - [pom.xml](https://oss.sonatype.org/service/local/artifact/maven/redirect?r=releases&g=org.mockito&a=mockito-inline&v=2.20.1&e=pom) in the Sonatype OSS 'release' repo.

Let's keep the ticket open until we add tests for the artifacts. @ming13, do you want to contribute a test that would verify artifact IDs? This should be a form of a Gradle task. The issue is fixed in 2.20.1. I've added tests to prevent the issue in the future.

Thanks again for reporting!!!
Artifact ID changes
Since `2.20.0` Mockito Maven artifact IDs [have changed](http://search.maven.org/#search%7Cga%7C1%7Cg%3A%22org.mockito%22).

* `mockito-android` → `android`
* `mockito-inline` → `inline`
* `mockito-junit-jupiter` → `junit-jupiter`

Not sure if it is an intended change or not, so decided to clarify things a bit. So... Is it an intended change? It isn’t mentioned in the changelog.
