JFrog, which hosted the JCenter repository for Java OSS libraries as part of its Bintray service, is sunsetting JCenter following Bintray's deprecation on May 1, 2021, to shift focus to the JFrog Platform. JCenter will transition to a read-only repository, redirecting requests to Maven Central, a more updated and widely supported repository for Java libraries. The sunset involves scheduled brown-outs starting with one-hour periods and culminating in a 24-hour period, leading up to a full redirection to Maven Central on August 15. Users relying on JCenter need to update their projects and remote repositories to ensure compatibility with Maven Central. Although most Maven packages from JCenter are available in Maven Central, there might be exceptions, prompting users to seek alternatives, such as contacting package owners or using internal repositories. JFrog encourages users to reach out for support if needed and advises checking Maven Central for the latest package versions.
