创建工单
去https://issues.sonatype.org/secure/Dashboard.jspa新建一个账号，登录后选择Create Issue，选择Community Support - Open Source Project Repository Hosting (OSSRH)以及New Project，其他按照你自己的项目情况填写。 发布完后几小时内会有工作人员问你是否有Group Id对应的那个域名的所有权，如果有的话就回复有（我一开始以为这是系统自动回复，没有管它，结果好几天过后还是没再回复过我…），然后就会得到Configuration has been prepared的回复，这个时候就可以准备发布了。如果自己没有域名的话可以挂在开源的域名下面，例如com.github.flyzy2005，这样一样可以发布。
生成密钥
我用的是windows，直接去https://www.gpg4win.org/download.html下载Gpg4win，安装好后通过gpg --version，出现版本等信息就安装成功了。（如果是Linux，可以通过yum install gpg安装） 设置名字+邮箱，其他可以使用默认值，记住输入的passphrase，后面部署会用到，这里用参考文章里的配图：
$ gpg --gen-

You need a user ID
to identify your
key; the software constructs the user ID
from the Real Name, Comment
and Email Address
in this form:
"Heinrich Heine (Der Dichter) <heinrichh@duesseldorf.de>"
Real name: iteblog
Email address: wyphao
.2007@
163.com
Comment: flink-elasticsearch-connector
You selected this USER-ID:
"iteblog (flink-elasticsearch-connector) <wyphao.2007@163.com>"
Change (N)ame, (C)omment, (E)mail
or (O)kay/(Q)uit? O
You need a Passphrase
to protect your secret
key.
We need
to generate a lot
of random bytes. It
is a good idea
to perform
some other action (type
on the keyboard, move the mouse, utilize the
disks) during the prime generation; this gives the random number
generator a better chance
to gain enough entropy.

配置pom.xml
配置项目pom.xml 主要需要配置parent结点，以及增加license、scm、developers信息，这里讲我自己的pom.xml作为一个参考：
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

配置Maven的settings.xml 安装配置好maven后，在maven的安装目录下的conf文件夹下找到settings.xml，设置如下：
<servers>
<server>
<id>sonatype-nexus-snapshots
</id>
<username>Sonatype网站的账号
</username>
<password>Sonatype网站的密码
</password>
</server>
<server>
<id>sonatype-nexus-staging
</id>
<username>Sonatype网站的账号
</username>
<password>Sonatype网站的密码
</password>
</server>
</servers>
123456789101112
账号密码就是第一步申请的Sonatype网站的账号密码。
部署Jar包
通过cmd进入到项目pom.xml所在的目录下，运行如下命令：
mvn clean deploy
-P sonatype
-oss-release -Darguments="gpg.passphrase=设置gpg设置密钥时候输入的Passphrase"
1
如果没有ERROR的话就deploy完成了，如果有ERROR就看错误信息是什么，解决了重新运行命令即可，运行完成的所有文件存在项目目录下的target文件夹里。
上传密钥
两句命令即可，首先查看自己key的编号：
gpg
--list-keys
1
找到 pub对应的那个编号，例如pub 2048R/8C473F5C 上传到key验证库：
-- .. ---
1
release jar包
如果前几个步骤全部正确完成，登录https://oss.sonatype.org/#stagingRepositories后，将Staging Rpositories拉到最下即可看到你刚刚发布的jar包，选择上方的Close，第一次好像会有工作人员回复你第一步Create的那个Issue（我的是回复了）Everything looks good! Now, all that’s left for you is to select that staging repository and click the “Release” button.，然后再点击Release即可，等2个小时左右即可在http://search.maven.org/看到你发布的jar包。
更新Jar包
只需要更新pom.xml里的version，再重新depoly，重新close，再release即可。（如果version没有改变则会覆盖掉中央仓库的当前版本）。

主要参考文章：https://www.iteblog.com/archives/1807.html，讲解的很清楚。 最后附上自己的项目以及Issue作为参考： https://issues.sonatype.org/browse/OSSRH-30758 https://github.com/Flyzy2005/daoutil
