Can't find my uploaded components in staging repositories

My project(webporter,created in issue OSSRH-31186 ) can be searched in http://search.maven.org/ while can NOT be found in "staging repositories".Why?

I have deployed my first release to https://oss.sonatype.org,and you can type "brianway" in the "artifact search" box or "welcome" search box to find it.But when I choose "staging repositories",there is no any repo related to "brianway",why?

I've read some blogs about how to deploy components to oss,and "staging repositories" is a necessary step,after which I should close and release the repo,and then close the issue OSSRH-31186.But I can't even find my code in staging repositories! What should I do next?

I don't know if I did something wrong or it will take some time to get the code to  "staging repositories"?How long will it take?

Hope for reply.
