The Java SDK uses the ASF managed Nexus repository. There is a snapshot one (where we publish nightly builds) and also a release one (where we place our release candidates). Once the release candidate is approved the Nexus repository has a way to publish it making it an official release. More details in Publishing Maven Artifacts[1].
