windows 7 x86-64
jdk1.6.0_27 32-bit（假定该环境中已经设置了jdk的环境变量）
maven 3.1.1
nexus-2.9.1-02-bundle
1）下载maven
访问maven官方网站http://maven.apache.org/，下载maven包。下载链接为：http://apache.fayea.com/apache-mirror/maven/maven-3/3.1.1/binaries/apache-maven-3.1.1-bin.zip
2）解压下载到的apache-maven-3.1.1-bin.zip到某个目录。（如E:\Eb\Apache Software Foundation\apache-maven-3.1.1）
3）设置环境变量。
第一，添加用户变量M2_HOME（实际应为M3_HOME，懒得改了，下面都用M2_吧），M2_HOME=E:\Eb\Apache Software Foundation\apache-maven-3.1.1
第二，添加用户变量M2，M2=%M2_HOME%\bin
第三，修改用户变量PATH（若没有此变量，则添加一个），PATH=%M2%;%PATH%
4）验证maven是否安装成功。打开命令行，输入mvn -v，显示如下信息即为安装成功。
1）下载nexus
访问nexus官方网站http://www.sonatype.org/nexus/，下载nexus-2.9.1-02-bundle.zip。 http://www.sonatype.org/nexus/archived
2）解压至某个目录（如E:\Eb\nexus-2.9.1-02-bundle）
3）开启jetty服务器。找到E:\Eb\nexus-2.9.1-02-bundle\nexus-2.9.1-02\bin\jsw\windows-x86-32（由于jdk安装的是32位版本，因此执行此目录下的文件）目录，执行console-nexus.bat批处理文件，等待命令行执行到如下情况：
不要关闭命令行窗口。
4）访问nexus管理页面。
打开浏览器，输入http://localhost:8081/nexus/，点击页面右上方的Log in超链接，输入默认用户名密码admin/admin123，登录nexus管理页面。
1）登录nexus管理页面，点击左侧的Repositories，显示相关的仓库信息，各个仓库的含义可自行百度之。
2）修改默认的存储路径。
安装nexus后，本地仓库默认的jar包存储位置是file:/E:/Eb/nexus-2.9.1-02-bundle/sonatype-work/nexus/storage/central。由于Central仓库占用存储较大，我们可以单独设置其存储位置。
首先，将E:/Eb/nexus-2.9.1-02-bundle/sonatype-work/目录下的所有内容复制到H:/Eb/nexus-2.9.1-02-bundle/sonatype-work/目录下；
第二，选中Central，打开Configuration选项卡，修改Override Local Storage Location项的值为file:/H:/Eb/nexus-2.9.1-02-bundle/sonatype-work/nexus/storage/central，点击页面下方的save按钮。
3）同步索引。
首先，选中Central，点击下方的Configuration选项卡。修改Download Remote Indexes项的值为True。点击页面下方的save按钮。
第二，右键点击Central，弹出菜单中点击Repair Index。
修改完成后的配置如下图：
4）Apache Snapshots和Codehaus Snapshots两个仓库也按照上述1）2）3）步骤修改，只是Override Local Storage Location项分别为file:/H:/Eb/nexus-2.9.1-02-bundle/sonatype-work/nexus/storage/apache-snapshots和file:/H:/Eb/nexus-2.9.1-02-bundle/sonatype-work/nexus/storage/codehaus-snapshots
1）在maven安装目录中找到maven的全局配置文件。E:\Eb\Apache Software Foundation\apache-maven-3.1.1\conf目录下的settings.xml文件。
2）将settings.xml修改为如下配置：
<?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

| it to several places.
|
| That repository definition will have a unique id, so we can create a mirror reference for that

| server for that repository.
