如果你想知道如何将你的作品发布到 Maven 中心，那么这个来自 Mohammad Nadeem 的分步指南就是为你准备的

如果您想知道如何将您的工件发布到 Maven 中心，那么这个分步指南就是为您准备的。小心，你需要 Github。

必备步骤

步骤1: 确保已经安装了 JDK、 Maven、 Github 等。

步骤2: 创建一个 Github 帐户，如果你还没有的话。

步骤3: 创建一个新的 Github 存储库。

步骤4: 添加一个新的 SSH 密钥到您的 Github 帐户

步骤5: 将代码推送到 Github。

步骤6: 注册一个 Sonatype Jira 帐户。

步骤7: 为新的项目托管创建一个 Jira 问题。点击这里查看示例请求。

步骤8: 安装 GNU PG。在操作系统中安装并验证如下:

C:\Users\Nadeem>gpg --version
gpg (GnuPG) 2.1.15
libgcrypt 1.7.3
Copyright (C) 2016 Free Software Foundation, Inc.
License GPLv3+: GNU GPL version 3 or later 
This is free software: you are free to change and redistribute it.
There is NO WARRANTY, to the extent permitted by law.

Home: C:/Users/Nadeem/AppData/Roaming/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

C:\Users\Nadeem>

步骤9: 生成密钥对。

C:\Users\Nadeem>gpg --full-gen-key
gpg (GnuPG) 2.1.15; Copyright (C) 2016 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.

gpg: keybox 'C:/Users/Nadeem/AppData/Roaming/gnupg/pubring.kbx' created
Please select what kind of key you want:
   (1) RSA and RSA (default)
   (2) DSA and Elgamal
   (3) DSA (sign only)
   (4) RSA (sign only)
Your selection? 1
RSA keys may be between 1024 and 4096 bits long.
What keysize do you want? (2048)
Requested keysize is 2048 bits
Please specify how long the key should be valid.
         0 = key does not expire
        = key expires in n days
      w = key expires in n weeks
      m = key expires in n months
      y = key expires in n years
Key is valid for? (0)
Key does not expire at all
Is this correct? (y/N) y

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

Real name: Nadeem Mohammad
Email address: coolmind182006@gmail.com

You selected this USER-ID:

Change (N)ame, (C)omment, (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.

步骤10: 输入密码短语。

发布步骤

步骤1: 向 POM 添加分布式管理部分。

添加部署插件。

maven-deploy-plugin
2.8.2


default-deploy
deploy

deploy

下面是您可以将分发管理部分添加到 POM 的地方:

ossrh
https://oss.sonatype.org/content/repositories/snapshots


ossrh
https://oss.sonatype.org/service/local/staging/deploy/maven2/

步骤2: 将 ossrh 服务器细节添加到 M2 _ REPO home 下的 setings.xml 中。

ossrh
your-jira-id
your-jira-pwd

注意: setings.xml 中服务器/服务器的 ID 元素应该与快照仓库的 ID 元素和 POM 文件中的仓库相同。

步骤3: 将 SCM 部分添加到 POM 中。

scm:git:git://github.com/dexecutor/dependent-tasks-executor.git
scm:git:git@github.com:dexecutor/dexecutor.git
https://github.com/dexecutor/dependent-tasks-executor
HEAD

步骤4: 添加 Maven 发布插件。

org.apache.maven.plugins
maven-release-plugin
2.5.3

true
false
forked-path
-Dgpg.passphrase=${gpg.passphrase}



org.apache.maven.scm
maven-scm-provider-gitexe
1.9.5

像在 Maven setings.xml 中添加配置文件一样添加 GPG 密码短语。

ossrh

true


[your_gpg_passphrase]

添加 Nexus 登台 Maven 插件。

org.sonatype.plugins
nexus-staging-maven-plugin
1.6.7
true

ossrh
https://oss.sonatype.org/
true

步骤5: 添加源代码和 javadoc 插件。

org.apache.maven.plugins
maven-source-plugin
3.0.1


attach-sources

jar

org.apache.maven.plugins
maven-source-plugin
2.10.4

UTF-8



attach-javadoc

步骤6: 配置为在释放时对工件进行签名。

release-sign-artifacts


performRelease
true





org.apache.maven.plugins
maven-gpg-plugin
1.6


sign-artifacts
verify

sign

步骤7: 发布 GPG 密钥对并将密钥分发到 GPG 服务器:

gpg –keyserver [KEY_SERVER] –send-key [KEY_ID]

上述情况下的 KEY _ ID 是5694AA563793429557F1727835B3BD2A223A。

其中一些关键服务器是:

• pool.sks-keyservers.net
• gnupg.net:11371
• keys.pgp.net
• surfnet.nl
• mit.edu

第八步: 发布！

mvn clean

mvn release:prepare

mvn release:perform

第9步: 推标签和代码到您的远程回购。

git push–tags

git push origin master

步骤10: 验证 sonatype 存储库。

步骤11: 更新 Sonatype Jira 票据。

有关详细信息，请参阅此示例 POM 文件。

如果出了问题怎么办

第一步: 撤销发布:

git reset –hard HEAD~1 (根据错误发生的时间，您可能需要再次执行此操作。)

步骤2: 删除标记。

git tag -d tagName

git push origin :refs/tags/tagName
