Artifact does not show up in Staging Repositories after successful deployment

I am trying to deploy an artifacts under the group id io.github.zhtmf using my https://oss.sonatype.org/ credentials.

I have successfully deployed and released several versions before, however this time the artifact does not show up in "Staging Repositories" section of my Nexus Repository at https://oss.sonatype.org/#stagingRepositories.

The deployment itself completes without error. I have done several deployments roughly 24 hours ago and I gave another try just now but the result is the same.

I am deploying a SNAPSHOT version using maven deploy plugin version 2.7 and the command "mvn clean deploy".

Part of the log file has been attached for your reference, please advise what I am missing or how can I resolve this problem.
