从零开始把项目发布到maven仓库中心

sonatype准备操作

注册账号

https://issues.sonatype.org

1. 密码符号规范，并且工记住

新建项目

1. group id 如果你有com域名的所有权可以直接使用，如果不符合可以使用com.github.{账号名来定义}
2. 如果有问题管理员会在下方留言通知你如下文（github所有权验证)

然后等会有类似的通知发出，并按通知进行操作。

When choosing a groupId that reflects your project hosting, in this case, something like io.github.ants-double or com.github.ants-double would be correct. Also, please create a public repo called OSSRH-52139 to verify github account ownership.

然后你就创建对应的公有仓库，等创建成功后在些回复一下，看到如下评论前期准备工作就正式结束了

com.github.ants-double has been prepared, now user(s) antsdouble,Ants-double can:

Deploy snapshot artifacts into repository https://oss.sonatype.org/content/repositories/snapshots
Deploy release artifacts into the staging repository https://oss.sonatype.org/service/local/staging/deploy/maven2
Release staged artifacts into repository 'Releases'
please comment on this ticket when you promoted your first release, thanks

GPG的准备工作

windows安装gpg https://www.gpg4win.org/get-gpg4win.html，这里使用git命令行工具

生成秘钥

gpg --gen-key 按照提示输入姓名/邮箱，然后按O即可生成

查看秘钥
```
gpg --list-keys
```
同步公钥

gpg --keyserver http://keys.gnupg.net:11371/ --send-keys [xxxxxxxxx] 其中的[xxxxxxxxx]，可用gpg --list-keys显示出来。
```

Maven准备工作

更新setting.xml文件添加仓库

<server>
  <id>sonatype-nexus-snapshots</id>
  <username>Sonatype账号</username>
  <password>Sonatype密码</password>
</server>
<server>
  <id>sonatype-nexus-staging</id>
  <username>Sonatype账号</username>
  <password>Sonatype密码</password>
</server>

修改pom.xml文件增加许可协议、SCM信息、开发者信息 (最后附完整的pom.xml文件)

打包发布

使用命令，一键打包。
```
`mvn clean deploy -P <profile-id>` 
```
打包过程中会要求输入gpg密钥的Passphase信息，输入即可

deploy

然后到https://oss.sonatype.org/#stagingRepositories 查看，看到如下信息
然后去账号下面去回复评论,大概意思是我弄完了，你处理一下吧
最后在 nexus repository manager中staging repositories选中最新发布的项目，然后执行
```
open -> closed
closed->release
执行完可以在activity中查看状态以角错误的原因
```
最后按官网上说的过一会，maven Center可以更久一点就能查到了。
```
https://search.maven.org/

https://mvnrepository.com/
```

出现的问题

java1.8javadoc严格验证

解决是添加
 <configuration>
                                    <additionalparam>-Xdoclint:none</additionalparam>
                                </configuration>

项目id不存在，解决是添加命名的项目id
