io.github.xxx has been prepared, now user(s) youname can: Publish snapshot and release artifacts to s01.oss.sonatype.org Have a look at this section of our official guide for deployment instructions: https://central.sonatype.org/publish/publish-guide/#deployment Depending on your build configuration, your first component(s) might be released automatically after a successful deployment. If that happens, you will see a comment on this ticket confirming that your artifact has synced to Maven Central. If you do not see this comment within an hour or two, you can follow the steps in this section of our guide: https://central.sonatype.org/publish/release/ ###### As part of our efforts to improve the security and quality posture of the open source supply chain, we plan to enable additional scanning of dependencies for security alerts soon. Since you're already hosting your source  code in Github, you can get these insights today by enabling Sonatype Lift. Sonatype Lift is free forever on public repositories! Lift tells you about open source vulnerabilities during code review, and goes beyond open source to scan your code for both code quality and security issues, providing feedback right in your pull requests.

Check the address is https://repo.maven.apache.org/maven2/io/github/xxx/tool/1.0.0

If the above connection can be found, it is already available for use in the project. The timing of the synchronization to the central warehouse is uncertain.

Problems encountered

• When executing MVN deploy, there is always a 401 error returned. We tried all kinds of methods but could not solve the problem. We just registered a new account.

• The repository location has changed and most of the articles on the web are now old and new
