1. 概述

maven仓库在sonatype管理，所以我们要在sonatype上创建账号并提交一个“我想发布项目”的issue。

另外，group id不要再使用com.github.xxx了！这个已经无效了！附图如下：

2. 在sonatype上发布issue

2.1. 创建sonatype账号

基操，不解释。登陆后可以选择中文界面。

sonatype网址System Dashboard - Sonatype JIRA

创建账号地址Sign up for Jira - Sonatype JIRA

2.2. 提issue

找到 提issue 的入口 image.png

2.3. 编辑issue

image.png image.png

  • 项目：Community Support - Open Source Project Repository Hosting (OSSRH)
  • 问题类型：New Project
  • 摘要：填项目名称就好
  • group id：
    • 如果是创建在git上的话，需要写成io.github.xxx
    • 如果是其他com.xxx地址的话，地址必须是可以访问的
  • project URL 和 SCM url：比如我的git上一个项目地址是github.com/HollandZang…

其他项默认和不填就行，依然能够审核通过

2.4. 等待答复、修改后重新提交

当管理员留下了修改意见之后，会把状态从open改成watting for response。 image.png

按照意向整改完成后，一定要记得点击response，把状态重新open，这样管理员才会继续跟进这个issue。

response按钮在这个位置。 image.png

点击response后的状态变更记录： image.png

2.5. issue关闭

3. 配置GPG

3.1. 下载安装

从www.gnupg.org/download/下载 GnuPG 的二进制文件 或使用您最喜欢的包管理器安装它，并通过运行带有--version标志的 gpg 命令来验证它。

$ gpg --version
gpg (GnuPG) 2.2.19
libgcrypt 1.8.5
Copyright (C) 2019 Free Software Foundation, Inc.
License GPLv3+: GNU GPL version 3 or later <https://gnu.org/licenses/gpl.html>
This is free software: you are free to change and redistribute it.
There is NO WARRANTY, to the extent permitted by law.

Home: /home/mylocaluser/.gnupg
Supported algorithms:
Pubkey: RSA, ELG, DSA, ECDH, ECDSA, EDDSA
Cipher: IDEA, 3DES, CAST5, BLOWFISH, AES, AES192, AES256, TWOFISH,
        CAMELLIA128, CAMELLIA192, CAMELLIA256
Hash: SHA1, RIPEMD160, SHA256, SHA384, SHA512, SHA224
Compression: Uncompressed, ZIP, ZLIB, BZIP2

3.2. 生成密钥对

$ gpg --gen-key
gpg (GnuPG) 2.2.19; Copyright (C) 2019 Free Software Foundation, Inc.
This is free software: you are free to change and redistribute it.
There is NO WARRANTY, to the extent permitted by law.

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: Central Repo Test //输入名称
Email address: central@example.com //输入邮箱
You selected this USER-ID:
"Central Repo Test <central@example.com>"

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

public and secret key created and signed.

pub   rsa3072 2021-06-23 [SC] [expires: 2023-06-23]
CA925CD6C9E8D064FF05B4728190C4130ABA0F98 //这个就是公钥
uid                      Central Repo Test <central@example.com>
sub   rsa3072 2021-06-23 [E] [expires: 2023-06-23]

找到GnuPG文件夹，把其下的bin目录加入到环境变量PATH中如D:\GnuPG\bin;。记得重启命令行工具或idea。 不然后面会提示

'gpg.exe'  is not recognized as an internal or external command, operable program or batch file - Maven Release Plugin

4. 配置maven

4.1. 配置setting.xml文件

<settings>
    <servers>
        <server>
            <id>ossrh</id>
            <username>your-jira-id</username> //sonatype的登录账号
            <password>your-jira-pwd</password> //sonatype的登录密码
        </server>
    </servers>
    
    <profiles>
        <profile>
            <id>ossrh</id>
            <activation>
                <activeByDefault>true</activeByDefault>
            </activation>
            <properties> //这个节点是mac用的，windows配上会出错
                <gpg.executable>gpg2</gpg.executable>
                <gpg.passphrase>the_pass_phrase</gpg.passphrase>
            </properties>
        </profile>
    </profiles>
</settings>

4.2. 配置pom依赖

5. 把项目发布到maven仓库

5.1. 部署到maven仓库mvn clean deploy

务必要mvn clean先，保持target干净

更新版本时也是用mvn clean deploy指令，但是要记得更新你的<version>标签

第一次会有如下提示，输入第三步GPG安装时的密码 image.png

5.2 如果报错了，检查一下节点是否都存在

Invalid POM: xxxxxx Project URL missing, License information missing

    </scm>
</project>

5.3. 发布成功

image.png

5.3.1 等待sonatype的回复

image.png

译：激活io.github.HollandZang的中央同步。成功发布之后，组件将被发布到Central repo1.maven.org/maven2/ ，通常在30分钟内，但更新到search.maven.org 可能需要4个小时。

5.3.2 可以先查看maven仓库

证明确实上传成功了，能够被访问了 image.png

5.3.3 查看最终结果

这个时候就可以通过pom直接引入依赖了。 顺便附上这次测试用的okhttp二次封装工具。 mvnrepository.com/artifact/io…
