发布Jar到Maven中央仓库--mvn

摘要

一、将项目推送到远程仓库,如 Github或者Gitee

二、注册 Sonatype 账户–就是一个JIRA

进入 https://issues.sonatype.org/secure/Dashboard.jspa 注册一个账号,邮箱要真实。

三、登录 Sonatype 创建工单–每部署一个新项目就创建一个工单

Summary:工单摘要,随便给个名称
Group Id:填写项目的Group Id
Project URL:填写远程仓库的浏览器地址
SCM url:填写下载项目的git地址
  • 注意:Group Id:最好填写你拥有的域名,比如我的域名是hanqunfeng.com,这里就填写com.hanqunfeng,这样后面验证domain时会方便一些。我第一次就是不知道这个事情,所以随便填的hanqf.org。

  • 创建好工单后会收到两封邮件:

    • 第一封,通知你创建工单成功。

    • 第二封邮件,要求你验证domain,两封邮件间隔大约5分钟。同时你在工单的注释中也能看到系统回复的同样的信息。

      Central OSSRH updated OSSRH-62247:
      ----------------------------------
      Status: Waiting for Response (was: Open)

      Do you own the domain hanqf.org? If so, please verify ownership via one of the following methods:
      * Add a TXT record to your DNS referencing this JIRA ticket: OSSRH-62247 (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 io.github.hanqunfeng or com.github.hanqunfeng

  • 看邮件说明,如果是自己的域名,添加一条TXT record 是最快速的验证方式,刚好我有一个域名,于是修改了工单的Group Id,修改工单时需要填写注释,随便填就行。

  • 然后去设置了DNS,一条TXT记录,key是工单号,我这里就是OSSRH-62247,值是工单地址,这里就是https://issues.sonatype.org/browse/OSSRH-62247,创建好后,在工单中添加一条注释

    1
    I have change the group Id to com.hanqunfeng,and I own the domain hanqunfeng.com,and I have added a dns record TXT.

    其它验证方式我并未尝试。

  • 过一会你就会收到回复邮件,通知你验证完成,可以发布了,并且给出了发布地址。

    • 注意这里是先发布到https://oss.sonatype.org,而不是maven中央仓库的地址。

四、发布

  • 1.准备签名

    • 可以使用工具创建密钥对
      需要下载一个签名工具,我是mac电脑,下载的是https://gpgtools.org
      安装后点击新建,按照提示创建一个密钥对即可,注意高级选项里有个过期时间,默认是3年。创建好后会主动提示你是否将公钥发布到key server,点击Upload Public key即可。也可以在创建后的证书列表页面邮件选择证书–>Send Public Key To Key Server。

      导出证书时,勾选密码并设置密码就是私钥和公钥证书,不勾选密码就是公钥,看生成文件的名称就可以,公开就是公钥,私密就是私钥,格式都是asc,其实就是字符串,可以用记事本打开查看。

      如果windows系统,可以下载https://www.gpg4win.org/ ,使用方式差不多,最后点击“将公钥上传的目录服务”。

      公钥发布到key server后要稍微等一会,大约10分钟吧,因为key server有多个,同步需要一些时间。
      记住你创建密钥对时的密码,发布项目时要使用。

    • 也可以使用命令行创建密钥对,版本[gpg (GnuPG/MacGPG2) 2.2.24]

      # 创建密钥对,按提示输入用户名称和邮箱地址
      gpg --generate-key

      # 列出密钥,hanqunfeng就是创建密钥对是的用户名,此处也可以使用邮箱
      # 结果中第二行一长串的后8位就是keyId,比如:30FF8D58,gradle构建时会用到
      gpg --list-keys hanqunfeng
      # 也可以直接通过id查询
      gpg --list-keys 30FF8D58

      # 上传公钥到server key,默认上传到hkps://keys.openpgp.org,但是提示上传失败
      # 看到网上的示例可以通过--keyserver指定上传的服务器地址,但是我这个版本[gpg (GnuPG/MacGPG2) 2.2.24]没有这个参数
      # 使用 https://gpgtools.org 上传公钥就会成功
      gpg --send-keys 30FF8D58

      # 查看指纹
      gpg --fingerprint 30FF8D58

      # 删除私钥,这里也可以使用用户名称或者邮箱,如果唯一的话
      gpg --delete-secret-keys 30FF8D58

      # 删除公钥
      gpg --delete-keys 30FF8D58
  • 2.settings.xml
    配置 maven 的 settings.xml 文件,设置一个 server,里面添加 Sonatype 的账号和密码。

    <username>Sonatype账号</username>
    <password>Sonatype密码</password>
    </server>
    </servers>
    </settings>
  • 3.pom.xml,重点是后面几个plugin
    这里重点说一下“nexus-staging-maven-plugin”这个插件,该插件会将我们发布到https://oss.sonatype.org的jar自动发布到maven中央仓库,如果没有这个插件,我们需要登录https://oss.sonatype.org,然后手工点击Staging Repositories ,找到你发布的包(GroupId开头的),然后点击close,再点击release。有说这种方式容易失败(我没有测试),推荐使用插件自动发布。

  • 4.执行命令

    1
    2
    3
    mvn clean package # 完成打包和测试
    mvn clean verify # 完成源码打包和javadoc打包,同时完成签名
    mvn clean deploy # 完成本地部署和maven中央仓库部署

    执行过程中会提示你输入创建密钥对时的密码,

    如果不想人工参与,也可以使用如下方式(参考:http://maven.apache.org/plugins/maven-gpg-plugin/usage.html)

    • a.在执行命令时指定密码:
      1
      mvn clean deploy -Dgpg.passphrase=thephrase
    • b.setting.xml中创建一个server

    提示你,大约10分钟后你就可以将依赖添加到项目中进行下载了,不过要通过search.maven.org检索到需要等待两个小时,毕竟更新索引也是需要时间的。
    另外,如果你确认发布是成功的,记得要回到工单添加个注释,如

    1
    I've released Releases successfully.Thank you!
  • 6.更新部署
    修改pom.xml中的版本号,重新执行mvn clean deploy即可。此时不会再收到sonatype发的邮件,依旧等待大约10分钟后你就可以将依赖添加到项目中进行下载了,同样search.maven.org检索到需要等待两个小时。
