步驟

申请sonatype账号

申请账号的地址在这里: https://issues.sonatype.org/secure/Signup!default.jspa
申请完成之后，我们需要提供相应的项目信息，地址在这里:https://issues.sonatype.org/secure/CreateIssue.jspa?issuetype=21&pid=10134
填写group Id，需要按要求填写
创建之后，等待审核

审核通过后

在收到邮件告知后，就可以上传包了

• 修改setting.xml，添加server项,录入账号密码

    <server>
  <id>nexus-releases</id>
  <username>xx</username>
  <password>xxxxx</password>
  

  nexus-snapshots xx xxxxx

修改pom.xml
譬如：https://github.com/jianliu/l-poi-excel/blob/master/pom.xml
需要注意的是，parent需要填写
还需要nameurldescriptionlicensesscmdevelopers
添加相应的插件 compirejavadoc eleases
添加部署的repositorysnapshotRepository

GPG秘钥生成

需要先下载gpg软件windows版本 https://gpg4win.org/download.html
按提示操作过程中，需要自己写一个key，在mvn clean deploy 录入对应的key来验证
gpg的作用是生成公钥，用于加密相关jar包
C:Usersxx>gpg --gen-key

Note: Use "gpg --full-generate-key" for a full featured key generation dialog.

GnuPG needs to construct a user ID to identify your key.

Real name: xxx
Email address: xxx@163.com
You selected this USER-ID:
"xxxxxx@163.com"

Change (N)ame, (E)mail, or (O)kay/(Q)uit? O
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.

打包、上传

首先将version修改为 1.0-SNAPSHOT 带上SNAPSHOT，表明它是快照版本
执行mvn clean deploy,期间会要求录入生成gpg秘钥时输入的密码，校验成功才会上传， 这时包就上传到远程本地仓库了，但其他人还不能下载

mvn release 插件并非必须的，在第一次发布时，只要符合规范，mvn clean deploy 就已经做完了全部事情
mvn release 主要用于将代码提交到远程仓库中去，并非必须品
执行
mvn release:prepare
mvn release:perform

正式发布

到https://oss.sonatype.org/#stagingRepositories登录，
选择自己的仓库，先CLOSE,再Release
如果是第一次发布，在Issue下告知一下工作人员
过一会就可以再maven中心仓库查看到了
