apache-maven-3.3.3和nexus2.11.1-01的配置

我是靠谱客的博主单薄果汁，最近开发中收集的这篇文章主要介绍apache-maven-3.3.3和nexus2.11.1-01的配置，觉得挺不错的，现在分享给大家，希望可以做个参考。

概述

以前一直用旧点的版本，今天（五一放假）整理来了下自己的软件，然后更新了下重要的两个：maven和nexus。

这里简单记录下自己的配置，用的都是最新的版本（截止到2015-05-02）：

首先写一下nexus的配置，因为我觉得先配置nexus再配置maven更方便，这样maven也不会直接到中央仓库下载jar包，下面是nexus的配置，就改两个地方：

1、配置java环境，最好jdk1.7以上的版本，理由是等下的maven3.3.3必须是jdk1.7以上才可以用。

配置文件路径：E:MySoftwarenexus2.11.1-01nexus-2.11.1-01binjswconfwrapper.conf

修改：找到大概15行的地方wrapper.java.command=java，改为wrapper.java.command=C:Program Files (x86)Javajdk1.7.0_72binjava，也就是jdk的路径

2、配置jetty的端口，由于我的nexus是直接使用内置的jetty服务器，而且我的window7系统的8081端口被占用了，也不知道是哪个软件占用的，所以直接修改jetty的端口为8181，

修改文件路径：E:MySoftwarenexus2.11.1-01nexus-2.11.1-01confnexus.properties

修改：找到application-port=8081这一句，直接修改端口为8181

修改好nexus的配置后就可以安装了，安装前，我把nexus的E:MySoftwarenexus2.11.1-01nexus-2.11.1-01bin目录添加到了系统的环境变量path中。然后在命令行进入到nexus的bin目录，运行一下命令安装nexus的服务：

1、nexus install 安装服务

2、nexus start 启动服务，其实就是启动jetty

如果启动成功会显示start successful，这时候在浏览器输入：http://localhost:8181/nexus/ 就可以看到nexus的界面了，登陆使用默认用户及密码：admin和admin123，登陆以后可以配置更多的nexus选项，我这里只要增加了一下代理仓库的地址，仓库的地址我单独写了一篇文章记录，nexus的仓库说明网上有很多，我这里不说了。上几张图吧

配置好nexus之后就配置maven，配置很简单：

1、把maven的E:MySoftwareapache-maven-3.3.3bin目录加到系统的path中。

2、配置文件：E:MySoftwareapache-maven-3.3.3confsettings.xml （maven的全局配置文件，所有用户都起作用）

文件内容：

 | 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.

 |
 |                 -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.

    <!-- server

     | 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

  <!-- 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
     | 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>
     -->
	 <!-- 设置全局镜像，所有下载从nexus下载 -->
	<mirror>
		<id>nexus-public</id>
		<name>nexus-public</name>
		<mirrorOf>*</mirrorOf>
		<url>http://localhost:8181/nexus/content/groups/public/</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.
   |
   |-->
  <profiles>
    <!-- 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.
    <profile>
      <id>jdk-1.4</id>

      <activation>
        <jdk>1.4</jdk>
      </activation>
