背景：

用了Maven以后，你有没有这样的想法，本身一直在使用别人贡献的代码，本身能不能把本身以为好的代码也贡献出来让你们方便。

还有若是你也是一名程序员，你会不会以为要是把本身积累起来平常经常使用的代码工具组件放到Maven的中央仓库以后，很方便维护和升级，

能够作到一次发布，处处使用。

不用交给云盘和代码托管系统来管理，只须要知道构件的坐标 + 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

准备工做：

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

这四步完成以后的结果：

5.到 https://github.com/ 网站注册一个帐号

6.到 https://issues.sonatype.org 网站注册一个帐号

动手实验：

(1) 在 https://github.com/ 网站建立一个仓库

图1-1：登录

图1-2：点击 “+” 好建立一个新的仓库

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：找到刚刚建立的仓库，获取仓库的https链接地址和ssh链接地址

HTTPS地址：

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

SSH地址：

git@github.com:zhangguangyong/codes.git

(2) 在 https://issues.sonatype.org 网站建立一个issues——建立的issues须要等待审核

图2-1：登录

图2-2：建立issues

图2-3：Issues的信息填写

Description 和 Attachment 不须要填写

点击Issues菜单，选择刚刚建立Issues,等待管理员的审批

审批经过以后，会看到这样的回复：

(3) 经过GnuGPG来建立一个公钥

(4) 建立一个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 >

图4-2：配置项目的pom.xml

项目的目录结构(这里是在eclipse中建立的,也能够本身手动建立)：

注意事项：settings.xml文件节点< sever> 下的 <id> 节点须要与 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

命令执行完以后，就能够到 https://oss.sonatype.org 下查看本身刚刚发布的构件了

(5) 到 https://oss.sonatype.org 仓库操做本身发布的构件(刚刚用maven发布的)——1.关闭，2.发布( 须要等到第(2)步的issues审核经过才能发布 )

图5-1：进入 https://oss.sonatype.org 查看本身发布的构件

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

关闭以后须要等待审批，审批成功以后，大概是这个样子：

关闭的审核经过以后，可进行发布了（在发布前须要确保以前建立Issues已经审批经过了，否则会报错没有权限）

这里报错的可能：

1. 刚刚建立的Issues尚未审批经过

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

(6) 在 https://oss.sonatype.org 发布成功以后，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，经过以后，就能够在 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管理员的反馈若是是这样的那恭喜你，你的构件就可以在maven中央仓库中搜索到了： http://search.maven.org/

图6-3：在 http://search.maven.org/ 上搜索本身的构件
