我们知道,Maven仓库包括本地仓库和远程仓库,而远程仓库又包括中央仓库,私服,Jboss仓库和Java.net仓库等。
私服,即私有的仓库服务器,它不仅可以降低中央仓库负荷,节省外网带宽,还可以加速Maven构建,自己部署构件等,从而高效地使用Maven。对于私服,我们可以使用仓库管理软件来创建自己的私有仓库服务器。目前网上流行的仓库管理软件有Apache的Achiva,JFrog的Artifactory和Sonatype的Nexus。由于当前Nexus是最流行的仓库管理软件,因此,我们这里采用Nexus。
Nexus的安装很简单,只需从http://nexus.sonatype.org/downloads下载最新的版本即可。需要注意的是官网向我们提供了两种安装方式,一种是自带Web容器(Jetty)的Bundle包,另外一种是war包。(可以直接部署到Tomcat等Web容器中)
假设下载的是Bundle包,解压到指定目录后(笔者的目录是E:\sonatype-nexus),进入目录E:\sonatype-nexus\nexus-2.4.0-09-bundle\nexus-2.4.0-09\bin\jsw\windows-x86-32\,找到脚本文件console-nexus.bat,打开并运行。如果没有出现错误,打开浏览器输入http://localhost:8081/nexus/index.html#welcome,可以看到nexus的欢迎界面:
默认情况下是匿名登录该网站,只能享受浏览,搜索等功能。如果想拥有更多控制能力,可以点击右上角的Login in进行登录,Nexus内置了一个管理员账户,用户名是admin,密码是admin123。
下面开始创建自己的宿主仓库,目的是为了将自己编写的构件部署到该仓库中,供组织其它成员下载。
用管理员账户登录之后,在左边导航栏框中找到Repositories,点击后,在右框中选择Add按钮,弹出的菜单中选择Hosted Repository,表示添加宿主仓库。
在新建宿主仓库表中,填写仓库的ID,Name以及仓库策略(release表示发布版构件,snapshot表示快照版构件),比如:
点击save按钮,完成策略为Release的宿主仓库创建。
同理,创建策略为Snapshot的宿主仓库。
至此,我们的宿主仓库(包括发布版和快照版)就完成了。
接下来,需要添加权限(Privileges)
在左边导航栏的Security中找到Privileges,点击后,在右框中点击Add按钮,选择Repository Target Privilleges
按如图所示添加发布版和快照版。
接下来创建具有相应权限的角色(Role)
最后创建用户。
这里需要注意的是,User ID就是远程仓库的username,password就是远程仓库的password。
至此,宿主仓库就算完成了。
因为远程仓库需要安全认证,所以需要在settings.xml中进行配置。
打开settings.xml,在settings根标签下添加如下内容:
<server> <id>pro-snapshot</id> <username>foo</username> <password>123456</password> </server> <server> <id>pro-release</id> <username>foo</username> <password>123456</password> </server>
安全认证配置好后,接下来打开你要部署的maven项目的pom.xml,在project元素下添加如下内容:
<distributionManagement> <repository> <id>pro-release</id> <name>Proj Release Repository</name> <url>http://localhost:8081/nexus/content/repositories/RestBus-Releases</url> </repository> <snapshotRepository> <id>pro-snapshot</id> <name>Proj Snapshot Repository</name> <url>http://localhost:8081/nexus/content/repositories/RestBus-Snapshots</url> </snapshotRepository> </distributionManagement>
这里在distributionManagement元素下添加了发布版仓库和快照版仓库,它们的id对应之前在settings.xml中server的id。url为仓库地址,该url可以在nexus的repositories中找到:
最后一步,打开命令提示符窗口,定位到maven根目录下(和pom.xml同目录),执行maven命令:
mvn clean deploy
如果配置没有错误,会出现以下类似打印信息:

当然,也可以在网页上进行手工部署。
