这篇文章主要讲怎样将自己的jar包上传到maven 中央仓库，以便在项目中直接使用而不用构建自己的私服
例如：
com.fundebug
fundebug-java
0.2.0
但是，Maven中央仓库并不支持直接发布jar包。我们需要将jar包发布到一些指定的第三方Maven仓库，然后该仓库再将jar包同步到Maven中央仓库。
其中，最"简单"的方式是通过Sonatype OSSRH仓库来发布jar包。接下来，我会介绍如何将jar包发布到Sonatype OSSRH。
本教程所使用的系统配置如下：
- OS: MacOS 10.14.1
- JDK：1.8.0_192
- Maven：3.5.4
下面开始配置
1、申请sonatype 账号
JIRA是一个项目管理服务，类似于国内的Teambition。Sonatype通过JIRA来管理OSSRH仓库。
注册地址：https://issues.sonatype.org/secure/Signup!default.jspa
2、创建issue
通过在JIRA上创建issue来申请发布新的jar包，Sonatype的工作人员会进行审核，审核不算严格，一般按照要求填写不会有问题。
创建链接：https://issues.sonatype.org/secure/CreateIssue.jspa?issuetype=21&pid=10134
创建issue的时候需要填写下面这些信息：
- Summary
简单描述一下你的项目内容 - Description
详细描述你的项目功能 - Group Id
你需要发布的项目的group Id - Project URL
你的开源项目的 github 或者gitee 地址 - SCM url
你的开源项目的github 或者 gitee 仓库地址
参考地址 https://issues.sonatype.org/browse/OSSRH-53141
提交申请之后 由于时差可能需要半天到一天才会有回复回复内容如下：
1573956962718.jpg
这个时候你需要把你的域名添加一天TEXT 解析：
OSSRH-xxxxx 到 https://issues.sonatype.org/browse/OSSRH-xxxxxx
添加完成之后需要回复此issue 告诉对方已经添加完成
没有什么问题的话 对方会审核通过并告诉你可以上传jar包的仓库了 此时你需要在上传第一个包的时候回复此issue
此时issue的status变为RESOLVED，我们就可以进行下一步操作了。
3、装并配置GPG
发布到Maven仓库中的所有文件都要使用GPG签名，以保障完整性。因此，我们需要在本地安装并配置GPG。
安装GPG
MacBook安装GPG非常简单，下载并安装GPG Suite即可。
生成GPG密钥对
gpg --gen-key
生成密钥时将需要输入name、email以及password。password在之后的步骤需要用到，请记下来。
上传GPG公钥
将公钥上传到公共的密钥服务器，这样其他人才可以通过公钥来验证jar包的完整性。
gpg --keyserver hkp://keyserver.ubuntu.com:11371 --send-keys CAB4165C69B699D989D2A62BD74A11D3F9F41243
其中CAB4165C69B699D989D2A62BD74A11D3F9F41243为密钥的ID，可以通过gpg --list-keys命令查看
gpg --list-keys
/Users/XXXXXX/.gnupg/pubring.kbx

4、 配置maven settings.xml 此配置文件在电脑位置可能不同， 根据各自的设置找到位置修改
ossrh
Fundebug
passsword
5、配置pom.xml
pom.xml挺长的。根据Sonatype OSSRH的要求，以下信息都必须配置：
- Supply Javadoc and Sources
- Sign Files with GPG/PGP
- Sufficient Metadata
- Correct Coordinates
- Project Name, Description and URL
- License Information
- Developer Information
- SCM Information
我的配置文件：
4.0.0
cn.ipokerface
mybatis
pom
1.0.0
IPoker-MybatisOperator
IPoker-MybatisGenerator
IPoker-MybatisGeneratorMavenPlugin
IPoker-Mybatis

6、发布Jar包
执行mvn clean deploy处理，即可将jar包发布到Sonatype OSSRH仓库。
mvn clean deploy -projects IPoker-MybatisOperator,IPoker-MybatisGenerator,IPoker-MybatisGeneratorMavenPlugin
我的项目含有多个模块，因此使用-projects选项来指定发布modules。
第一次执行mvn clean deploy命令时，需要输入GPG密钥的密码。
mvn clean deploy命令执行成功的输出是这样的(部分日志)：

7、 确认发布 close release
mvn clean deploy命令执行成功，使用sonatype账号登陆：https://oss.sonatype.org/#stagingRepositories，就可以看到你所发布的jar包了：
1573988566583.jpg
选中对于的repository之后，点击箭头所指的close，close时会检查发布的构件是否符合要求。若符合要求，则close成功，成功之后点击箭头所指的release，即可正式将jar包发布到Sonatype OSSRH仓库。
如果需要重新发布或者发布更新包，则重复6、7步就可以了
