$ 创建Issue工单
https://issues.sonatype.org/secure/Dashboard.jspa
Project: Community Support - Open Source Project Repository Hosting
Issue Type: New Project
Summary: marathon-client
Group Id: io.github.google
Project URL: https://github.com/google/cli-maven-plugin
SCM url: https://github.com/google/cli-maven-plugin.git
$ 确认域名归属
create a public repo called [
OSSRH-50621] to verify github account ownership.
$ 配置gpg-key
生成key（需要填写用户名、邮箱等信息，其中填写的Passphase需要记住）：
$ gpg --gen-key
列出公钥信息（其中824B4D7A为公钥）：
$ gpg --list-keys
---------------------------------------------
pub 2048R/824B4D7A 2016-01-06
uid [ultimate] user123 <user123@gmail.com>
sub 2048R/7A10AD69 2016-01-06
或者这种形式（其中F88223C1F1461D8A5D6296A55EE3D769D3501C8D为公钥）：
$ gpg --list-keys
----------------------------
pub rsa2048 2020-01-31 [SC] [expires: 2022-01-30]
F88223C1F1461D8A5D6296A55EE3D769D3501C8D
uid [ultimate] user123 <user123@gmail.com>
sub rsa2048 2020-01-31 [E] [expires: 2022-01-30]
上传公钥至密钥服务器：
$ gpg --keyserver hkp://pgp.mit.edu --send-keys 824B4D7A
验证是否成功：
$ gpg --keyserver hkp://pgp.mit.edu --recv-keys 824B4D7A
验证成功：
gpg: key 3D869D3: "user123 <user123@gmail.com>" not changed
gpg: Total number processed: 1
gpg: unchanged: 1
