上传自己的构件(Jar)到Maven中央仓库

背景：

用了Maven之后，你有没有这样的想法，自己一直在使用别人贡献的代码，自己能不能把自己觉得好的代码也贡献出来让大家方便。

还有如果你也是一名程序员，你会不会觉得要是把自己积累起来日常常用的代码工具组件放到Maven的中央仓库之后，很方便维护和升级，

可以做到一次发布，到处使用。

不用交给云盘和代码托管系统来管理，只需要知道构件的坐标 + Maven之类的构建工具就能获取想要的构件。

预备知识：

1.Java

http://www.oracle.com/technetwork/cn/java/javase/downloads/index.html

2.Maven

https://maven.apache.org/

3.Git

https://git-scm.com/

4. GnuGPG(gpg4win)

http://gpg4win.org/

5.Github

https://github.com/

6.Sonatype公司提供的

https://issues.sonatype.org

https://oss.sonatype.org

7.大概结构图

准备工作：

1.JDK安装配置

2 . Maven安装配置

3 . Git安装配置(可选)

4 . OpenGPG安装配置

这四步完成之后的结果：

5.到 https://github.com/ 网站注册一个账号

6.到 https://issues.sonatype.org 网站注册一个账号

动手实验：

(1) 在 https://github.com/ 网站创建一个仓库

图1-1：登陆

图1-2：点击 “+” 好创建一个新的仓库

图1-3：仓库的信息填写，这里的必填项是仓库的名称Respository name

图1-4：找到刚刚创建的仓库，获取仓库的https连接地址和ssh连接地址

HTTPS地址：

https://github.com/zhangguangyong/codes.git

SSH地址：

git@github.com:zhangguangyong/codes.git

(2) 在 https://issues.sonatype.org 网站创建一个issues——创建的issues需要等待审核

图2-1：登陆

图2-2：创建issues

图2-3：Issues的信息填写

Description 和 Attachment 不需要填写

点击Issues菜单，选择刚刚创建Issues,等待管理员的审批

审批通过之后，会看到这样的回复：

(3) 通过GnuGPG来创建一个公钥

(4) 创建一个Maven项目 —— 配置 settings.xml、pom.xml、发布到 https://oss.sonatype.org 仓库

图4-1：配置maven安装目录下 conf/settings.xml 文件

settings.xml文件的内容：

<!-- | This is the configuration file for Maven. It can be specified at two

levels: | | 1. User Level. This settings.xml file provides configuration

for a single user, | and is normally provided in ${user.home}/.m2/settings.xml.

| | NOTE: This location can be overridden with the CLI option: | | -s /path/to/user/settings.xml

| | 2. Global Level. This settings.xml file provides configuration for all

Maven | users on a machine (assuming they're all using the same Maven | installation).

It's normally provided in | ${maven.home}/conf/settings.xml. | | NOTE: This

location can be overridden with the CLI option: | | -gs /path/to/global/settings.xml

| | The sections in this sample file are intended to give you a running start

at | getting the most out of your Maven installation. Where appropriate,

the default | values (values used when the setting is not specified) are

provided. | | -->

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"

xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">

<!-- localRepository | The path to the local repository maven will use to

store artifacts. | | Default: ${user.home}/.m2/repository <localRepository>/path/to/local/repo</localRepository> -->

<localRepository>D:/Dev/Repos/Maven</localRepository>

<!-- interactiveMode | This will determine whether maven prompts you when

it needs input. If set to false, | maven will use a sensible default value,

perhaps based on some other setting, for | the parameter in question. | |

Default: true <interactiveMode>true</interactiveMode> -->

<!-- offline | Determines whether maven should attempt to connect to the

network when executing a build. | This will have an effect on artifact downloads,

artifact deployment, and others. | | Default: false <offline>false</offline> -->

<!-- pluginGroups | This is a list of additional group identifiers that

will be searched when resolving plugins by their prefix, i.e. | when invoking

a command line like "mvn prefix:goal". Maven will automatically add the group

identifiers | "org.apache.maven.plugins" and "org.codehaus.mojo" if these

are not already contained in the list. | -->

<!-- pluginGroup | Specifies a further group identifier to use for plugin

lookup. <pluginGroup>com.your.plugins</pluginGroup> -->

</pluginGroups>

<!-- proxies | This is a list of proxies which can be used on this machine

to connect to the network. | Unless otherwise specified (by system property

or command-line switch), the first proxy | specification in this list marked

as active will be used. | -->

<!-- proxy | Specification for one proxy, to be used in connecting to the

network. | <proxy> <id>optional</id> <active>true</active> <protocol>http</protocol>

<username>proxyuser</username> <password>proxypass</password> <host>proxy.host.net</host>

<port>80</port> <nonProxyHosts>local.net|some.host.com</nonProxyHosts> </proxy> -->

</proxies>

<!-- servers | This is a list of authentication profiles, keyed by the server-id

used within the system. | Authentication profiles can be used whenever maven

must make a connection to a remote server. | -->

<!-- server | Specifies the authentication information to use when connecting

to a particular server, identified by | a unique name within the system (referred

to by the 'id' attribute below). | | NOTE: You should either specify username/password

OR privateKey/passphrase, since these pairings are | used together. | <server>

<id>deploymentRepo</id> <username>repouser</username> <password>repopwd</password>

</server> -->

<!-- Another sample, using keys to authenticate. <server> <id>siteServer</id>

<privateKey>/path/to/private/key</privateKey> <passphrase>optional; leave

empty if not used.</passphrase> </server> -->

<username>zhanggy</username>

<password>xxxxxxxx</password>

</server>

</servers>

<!-- mirrors | This is a list of mirrors to be used in downloading artifacts

from remote repositories. | | It works like this: a POM may declare a repository

to use in resolving certain artifacts. | However, this repository may have

problems with heavy traffic at times, so people have mirrored | it to several

places. | | That repository definition will have a unique id, so we can create

a mirror reference for that | repository, to be used as an alternate download

site. The mirror site will be the preferred | server for that repository.

| -->

<!-- mirror | Specifies a repository mirror site to use instead of a given

repository. The repository that | this mirror serves has an ID that matches

the mirrorOf element of this mirror. IDs are used | for inheritance and direct

lookup purposes, and must be unique across the set of mirrors. | <mirror>

<id>mirrorId</id> <mirrorOf>repositoryId</mirrorOf> <name>Human Readable

Name for this Mirror.</name> <url>http://my.repository.com/repo/path</url>

</mirror> -->

</mirrors>

<!-- profiles | This is a list of profiles which can be activated in a variety

of ways, and which can modify | the build process. Profiles provided in the

settings.xml are intended to provide local machine- | specific paths and

repository locations which allow the build to work in the local environment.

| | For example, if you have an integration testing plugin - like cactus

- that needs to know where | your Tomcat instance is installed, you can provide

a variable here such that the variable is | dereferenced during the build

process to configure the cactus plugin. | | As noted above, profiles can

be activated in a variety of ways. One way - the activeProfiles | section

of this document (settings.xml) - will be discussed later. Another way essentially

| relies on the detection of a system property, either matching a particular

value for the property, | or merely testing its existence. Profiles can also

be activated by JDK version prefix, where a | value of '1.4' might activate

a profile when the build is executed on a JDK version of '1.4.2_07'. | Finally,

the list of active profiles can be specified directly from the command line.

| | NOTE: For profiles defined in the settings.xml, you are restricted to

specifying only artifact | repositories, plugin repositories, and free-form

properties to be used as configuration | variables for plugins in the POM.

| | -->

<!-- profile | Specifies a set of introductions to the build process, to

be activated using one or more of the | mechanisms described above. For inheritance

purposes, and to activate profiles via <activatedProfiles/> | or the command

line, profiles have to have an ID that is unique. | | An encouraged best

practice for profile identification is to use a consistent naming convention

| for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey',

'user-brett', etc. | This will make it more intuitive to understand what

the set of introduced profiles is attempting | to accomplish, particularly

when you only have a list of profile id's for debug. | | This profile example

uses the JDK version to trigger activation, and provides a JDK-specific repo.

<repository> <id>jdk14</id> <name>Repository for JDK 1.4 builds</name> <url>http://www.myhost.com/maven/jdk14</url>

<layout>default</layout> <snapshotPolicy>always</snapshotPolicy> </repository>

</repositories> </profile> -->

<!-- | Here is another profile, activated by the system property 'target-env'

with a value of 'dev', | which provides a specific path to the Tomcat instance.

To use this, your plugin configuration | might hypothetically look like:

| | <configuration> | <tomcatLocation>${tomcatPath}</tomcatLocation> | </configuration>

| </plugin> | ... | | NOTE: If you just wanted to inject this configuration

whenever someone set 'target-env' to | anything, you could just leave off

the <value/> inside the activation-property. | <profile> <id>env-dev</id>

<activation> <property> <name>target-env</name> <value>dev</value> </property>

</activation> <properties> <tomcatPath>/path/to/tomcat/instance</tomcatPath>

</properties> </profile> -->

</profiles>

<!-- activeProfiles | List of profiles that are active for all builds. |

<activeProfiles> <activeProfile>alwaysActiveProfile</activeProfile> <activeProfile>anotherAlwaysActiveProfile</activeProfile>

</activeProfiles> -->

</ settings >

注意事项：settings.xml文件节点< sever> 下的 <id> 节点需要与 pom.xml 文件节点 <snapshotRepository> 和节点 <repository> 下的 <id> 节点保持一致

图4-3：发布项目到 https://oss.sonatype.org 仓库

使用命令cmd到项目的根路径

执行命令：mvn clean deploy -P release

命令执行完之后，就可以到 https://oss.sonatype.org 下查看自己刚刚发布的构件了

(5) 到 https://oss.sonatype.org 仓库操作自己发布的构件(刚刚用maven发布的)——1.关闭，2.发布( 需要等到第(2)步的issues审核通过才能发布 )

图5-1：进入 https://oss.sonatype.org 查看自己发布的构件

找到自己发布的构建，点击关闭 ( 找组名是：com.github.xxx 开头的，我们刚刚在pom.xml里面填写的组件就是 com.github.zhangguangyong)

关闭之后需要等待审批，审批成功之后，大概是这个样子：

关闭的审核通过之后，可进行发布了（在发布前需要确保之前创建Issues已经审批通过了，不然会报错没有权限）

这里报错的可能：

1. 刚刚创建的Issues还没有审批通过

2. 项目的pom.xml里面的< groupId > 与创建Issues时候填写的 group Id 不一致

(6) 在 https://oss.sonatype.org 发布成功之后，再去 https://issues.sonatype.org 给管理员一个反馈，说: "你的构件已经发布成功了".

在 https://issues.sonatype.org 等待管理员的审核，通过之后，就可以在 http://search.maven.org/ 上面所搜你发布的构件了

图6-1：通知Issues的管理员，你的构件在 https://oss.sonatype.org 上成功发布

图6-2：Issues管理员的反馈如果是这样的那恭喜你，你的构件就能够在maven中央仓库中搜索到了： http://search.maven.org/

图6-3：在 http://search.maven.org/ 上搜索自己的构件
