背景：

用了Maven以後，你有沒有這樣的想法，本身一直在使用別人貢獻的代碼，本身能不能把本身以爲好的代碼也貢獻出來讓你們方便。

還有若是你也是一名程序員，你會不會以爲要是把本身積累起來平常經常使用的代碼工具組件放到Maven的中央倉庫以後，很方便維護和升級，

能夠作到一次發佈，處處使用。

不用交給雲盤和代碼託管系統來管理，只須要知道構件的座標 + Maven之類的構建工具就能獲取想要的構件。

預備知識：

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.大概結構圖

準備工做：

1.JDK安裝配置

2 . Maven安裝配置

3 . Git安裝配置(可選)

4 . OpenGPG安裝配置

這四步完成以後的結果：

5.到 https://github.com/ 網站註冊一個帳號

6.到 https://issues.sonatype.org 網站註冊一個帳號

動手實驗：

(1) 在 https://github.com/ 網站建立一個倉庫

圖1-1：登錄

圖1-2：點擊「+」好建立一個新的倉庫

圖1-3：倉庫的信息填寫，這裏的必填項是倉庫的名稱Respository name

圖1-4：找到剛剛建立的倉庫，獲取倉庫的https鏈接地址和ssh鏈接地址

HTTPS地址：

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

SSH地址：

git@github.com:zhangguangyong/codes.git

(2) 在 https://issues.sonatype.org 網站建立一個issues——建立的issues須要等待審覈

圖2-1：登錄

圖2-2：建立issues

圖2-3：Issues的信息填寫

Description 和 Attachment 不須要填寫

點擊Issues菜單，選擇剛剛建立Issues,等待管理員的審批

審批經過以後，會看到這樣的回覆：

(3) 經過GnuGPG來建立一個公鑰

參考： http://my.oschina.net/huangyong/blog/226738

(4) 建立一個Maven項目 —— 配置 settings.xml、pom.xml、發佈到 https://oss.sonatype.org 倉庫

<!-- | 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 >

注意事項：settings.xml文件節點< sever> 下的 <id> 節點須要與 pom.xml 文件節點 <snapshotRepository> 和節點 <repository> 下的 <id> 節點保持一致

圖4-3：發佈項目到 https://oss.sonatype.org 倉庫

使用命令cmd到項目的根路徑

執行命令：mvn clean deploy -P release

命令執行完以後，就能夠到 https://oss.sonatype.org 下查看本身剛剛發佈的構件了

(5) 到 https://oss.sonatype.org 倉庫操做本身發佈的構件(剛剛用maven發佈的)——1.關閉，2.發佈( 須要等到第(2)步的issues審覈經過才能發佈 )

圖5-1：進入 https://oss.sonatype.org 查看本身發佈的構件

找到本身發佈的構建，點擊關閉 ( 找組名是：com.github.xxx 開頭的，咱們剛剛在pom.xml裏面填寫的組件就是 com.github.zhangguangyong)

關閉以後須要等待審批，審批成功以後，大概是這個樣子：

關閉的審覈經過以後，可進行發佈了（在發佈前須要確保以前建立Issues已經審批經過了，否則會報錯沒有權限）

這裏報錯的可能：

1. 剛剛建立的Issues尚未審批經過

2. 項目的pom.xml裏面的< groupId > 與建立Issues時候填寫的 group Id 不一致

(6) 在 https://oss.sonatype.org 發佈成功以後，再去 https://issues.sonatype.org 給管理員一個反饋，說: "你的構件已經發布成功了".

在 https://issues.sonatype.org 等待管理員的審覈，經過以後，就能夠在 http://search.maven.org/ 上面所搜你發佈的構件了

圖6-1：通知Issues的管理員，你的構件在 https://oss.sonatype.org 上成功發佈

圖6-2：Issues管理員的反饋若是是這樣的那恭喜你，你的構件就可以在maven中央倉庫中搜索到了： http://search.maven.org/

圖6-3：在 http://search.maven.org/ 上搜索本身的構件
