上传自己的包至maven中央仓库 author: Tank

上传JAR包前的准备工作

• 注册账号

  注册地址 此处注册的账号密码是需要记下来的。因为在上传时需要配置settings.xml内

• 创建工单 （也就是issues）可以参考我的

  • Project：自己项目名

  • Issue Type：选择创建新项目

  • Summary：随意命名

  • Group Id：唯一标识，这里需要注意，group id必须是自己的。一般是域名反推如我的。com.plumelog

  • Project URL：项目地址，我用的是官网地址如www.plumelog.com

  • SCM url：项目管理地址，如：https://gitee.com/frankchenlong/plumelog

    

• 发布issues后需要等待官方审核,审核后会回复如下

  Do you own the domain plumelog.com? If so, please verify ownership via one of the following methods:
  
  Add a TXT record to your DNS referencing this JIRA ticket: OSSRH-58071 (Fastest)
  Setup a redirect to your Github page (if it does not already exist)
  If you do not own this domain, please read:
  http://central.sonatype.org/pages/choosing-your-coordinates.html
  You may also choose a groupId that reflects your project hosting, in this case, something like
  
  Would you like to use a free managed security reporting service (recommended)?
  Put https://hackerone.com/central-security-project/reports/new as your project's security issue reporting URL. We'll take care of the rest.
  For more details on the Central Security Project, visit https://www.sonatype.com/central-security-project

  注意事项：

  上面填的group id 的反向域名他会问你是不是你所有。如果是需要配置一个txt的解析。最好是自己申请一个域名。可以避免不少坑。当你配置好txt解析后可以截图发给他，他会去验证

  

当他验证完成后会回复如下：也就是你可以上传你的包了

com.plumelog has been prepared, now user(s) tank 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 密钥生成

• 先下载GPG 下载安装gpg,https://www.gpg4win.org/download.html

  执行命令： gpg –gen-key 即可生成密钥 这里就不截图了，过程中需要填写一个密码，记住他，下一步打包上传的时候需要它。打开GPG窗口可以看到如下

  

  点击箭头处，将公钥发送到服务器

上传jar

这个过程可能会有点慢，上传时会有点卡过程中需要填写一个密码 也就是生成gpg时填的密码。

mvn clean deploy 即可将jar上传到https://oss.sonatype.org/ 这是一个临时存入jar 的地方

当上传完成后可以至https://oss.sonatype.org/#welcome 查看

点Release即可同步至中央仓库，这中间需要等待一段时间。然后就可以在中央仓库查询到了
