0.安装环境

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.安装maven3.1.1

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。

2.安装nexus

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。

3.配置nexus

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。Repair Index过程可能较慢，等待一会儿，进度可以从命令行窗口的日志中看到。

（注意以下问题：

关于Apache Snapshots 仓库无法拉取的问题：
nexus默认配置的是如下路径：
http://repository.apache.org/snapshots/
然后更新索引的时候日志中会提示：
jvm 1 | 2013-11-02 19:23:34 INFO [pxpool-1-thread-3] admin org.sonatype.nexus.index.DefaultIndexerManager - Cannot fetch remote index for repository "Apache Snapshots" [id=apache-snapshots] as it does not publish indexes.
正确的地址是如下这个：
https://repository.apache.org/content/repositories/releases/ release版本
https://repository.apache.org/content/repositories/snapshots/ 非稳定版本
请在仓库配置中更新地址即可。--参照连接http://leeon.me/a/use-cubieboard-to-build-maven-repo）

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

注：还有一个更彻底的方式，直接修改E:\Eb\nexus-2.9.1-02-bundle\nexus-2.9.1-02\conf\nexus.properties中的配置项nexus-work如下：

[plain] view plain copy

# Nexus section
#nexus-work=${bundleBasedir}/../sonatype-work/nexus
nexus-work=H:/Eb/nexus-2.9.1-02-bundle/sonatype-work/nexus
runtime=${bundleBasedir}/nexus/WEB-INF

4.配置maven使用nexus

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：

[html] view plain copy

<?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"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
<localRepository>E:/.m2/repository</localRepository>
<pluginGroups>
</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.
|-->
<proxies>
<!-- proxy
| Specification for one proxy, to be used in connecting to the network.

</proxy>
-->
</proxies>
<!-- servers

| Authentication profiles can be used whenever maven must make a connection to a remote server.
|-->
<servers>
</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.
|-->
<mirrors>
<mirror>

profile below over to a different nexus group -->

<activeProfile>anotherAlwaysActiveProfile</activeProfile>
</activeProfiles>
-->
<activeProfiles>
<activeProfile>development</activeProfile>
</activeProfiles>
</settings>

3）验证是否设置成功。

打开命令行，执行如下语句：

[plain] view plain copy

mvn help:system

之后，查看E:/.m2/repository（<localRepository>E:/.m2/repository</localRepository>将maven的默认配置改为该目录，默认配置为C:\Users\<用户名>\.m2\repository）和file:/H:/Eb/nexus-2.9.1-02-bundle/sonatype-work/nexus/storage/central两个目录下都有了新下载到的jar包。则表示配置成功。
