本博客曾经介绍了《如何手动添加依赖的jar文件到本地Maven仓库》这里的方法非常的简单,而且局限性很大:只能提供给本人开发使用,无法共享给其他需要的人。本文将介绍如何把自己开发出来的Java包发布到Maven中央仓库(http://search.maven.org/),这样任何人都可以搜索到这个包并使用它。如果你现在还不了解Maven是啥东西,请你先找本Maven书看看。
将自己的Java包发布到Maven中央仓库需要经过许多繁琐的步骤,本文将详细地介绍这些步骤。相信大家在看完本文之后也会发布jar包到Maven中央仓库。

创建工单
https://issues.sonatype.org/secure/Dashboard.jspa
在发布Java包到Maven中央仓库首先需要在https://issues.sonatype.org/secure/Dashboard.jspa网站创建一个工单(Issues),第一次使用这个网站的时候需要注册自己的帐号(这个帐号和密码需要记住,后面会用到),之后创建自己的Issue,点击导航最上面的Create
按钮,然后会弹出下面的对话框,将Project
和Issue Type
设置为下图的内容:

然后根据你Java包的功能分别写上Summary
、Description
、Group Id
、SCM url
以及Project URL
等必要信息,可以参见我之前创建的Issue:https://issues.sonatype.org/browse/OSSRH-24874。创建完之后需要等待Sonatype的工作人员审核处理,审核时间还是很快的,我的审核差不多等待了两小时。当Issue的Status变为RESOLVED
后,就可以进行下一步操作了。
如果你的Group Id填写的是自己的网站(我的就是这种情况),Sonatype的工作人员会询问你那个Group Id是不是你的域名,你只需要在上面回答是就行,然后就会通过审核。
使用gpg生成密钥对
上面创建的issuce经过审核之后,我们可以使用gpg生成密钥对,这里分两种情况:
1、如果使用的是Windows,可以到https://www.gpg4win.org/download.html下载gpg4win,推荐使用 Gpg4win-Vanilla 2.3.3版本,因为它仅包括 GnuPG,这个工具才是我们所需要的;
2、如果使用的是Linux,可以通过yum install gpg
命令安装gpg。
之后可以通过gpg --version
命令查看是否安装成功,如果出现版本等信息说明安装成功了,如下:
[[email protected] ~] $ gpg --version
gpg (GnuPG) 2.0.14
libgcrypt 1.4.5

安装完gpg之后,下面一次按照如下的命令设置好你的名字,邮箱,其他步骤可以使用默认值。不过输入Passphrase的值需要记住,这个相当于密钥的密码,发布过程中进行签名操作的时候会用到:
$ gpg --gen-key
gpg (GnuPG) 1.4.19; Copyright (C) 2015 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.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?
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) YYou need a user ID to identify your key; the software constructs the user ID
from the Real Name, Comment and Email Address in this form:
"Heinrich Heine (Der Dichter) [email protected]"Real name: iteblog
Email address: [email protected]
Comment: flink-elasticsearch-connector
You selected this USER-ID:
"iteblog (flink-elasticsearch-connector) [email protected]"Change (N)ame, (C)omment, (E)mail or (O)kay/(Q)uit? O
You need a Passphrase to protect your secret key.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.

到这里我们就设置好密钥对了。上面代码中导数第四行的B15C5AA3
需要记住,其相当于我们生成的key,后面会用到。
设置Maven配置
为了发布更简便,我们可以工程的pom.xml文件里面加入以下的配置:
org.sonatype.oss
oss-parent
7
并增加Licenses、SCM、Developers信息:
The Apache Software License, Version 2.0
http://www.apache.org/licenses/LICENSE-2.0.txt
repo
https://github.com/397090770/flink-elasticsearch2-connector
[email protected]:397090770/flink-elasticsearch2-connector.git
https://www.iteblog.com
iteblog
[email protected]
https://www.iteblog.com
最后修改Maven的setting.xml配置文件,设置如下:
sonatype-nexus-snapshots
Sonatype网站的账号
Sonatype网站的密码
sonatype-nexus-staging
Sonatype网站的账号
Sonatype网站的密码
上面的username和password就是你在步骤一注册的帐号和密码。
部署和发布Jar包
配置好pom.xml文件和Maven的setting.xml文件之后,我们就可以部署Jar包了,运行如下命令:
$ mvn clean deploy -P sonatype-oss-release -Darguments="gpg.passphrase=设置gpg设置密钥时候输入的Passphrase"

运行上面的命令之后,我们再上传到第三方的key验证库,如下:
$ gpg --list-keys
/c/Users/iteblog/.gnupg/pubring.gpg
pub 2048R/B15C5AA3 2016-09-19
uid iteblog (flink-elasticsearch-connector) [email protected]
sub 2048R/31A906E1 2016-09-19iteblog@iteblog MINGW64 /d/work/flink-elasticsearch2-connector (master)
$ gpg --keyserver hkp://keyserver.ubuntu.com:11371 --send-keys B15C5AA3
gpg: sending key B15C5AA3 to hkp server keyserver.ubuntu.com
之后我们的Java包将会发布到sonatype的构件仓库中,可以到https://oss.sonatype.org/#stagingRepositories查看发布好的Jar。进入之后会看到中间一个Table窗口,将滑动条移到最后,找到我们刚刚发布的Jar包,然后依次点击上方的Close–>Confirm
,这将会弹出类似于下面的对话框,在其中输入我们Jar包的描述信息,这个信息将会在Maven搜索结果当作简介介绍我们Jar包的,所以建议输的详细点。

当状态变成closed后,执行Release–>Confirm
,同样会弹出一个类似于上面的对话框,我们还是输入那些介绍信息即可,当这步执行完之后,构件将会自动删除,并经过几小时后便可以在Maven中央仓库搜索到(http://search.maven.org)。如下:

升级Jar包
我们开发的Jar包在后面可能需要更新,比如从1.0.1版本升级到1.0.2版本。升级Jar包比初次发布的步骤简单的多,我们只需要更新项目工程代码,并修改pom.xml文件里面的版本号,最后重新执行上面的部署和发布Jar包步骤即可。
