maven安装配置

安装配置

1.官网下载maven，解压到某个路径。

2.配置环境变量MAVEN_HOME=安装路径。

3.在环境变量path中加入%MAVEN_HOME%/bin或$MAVEN_HOME/bin

maven修改本地仓库地址

1.创建一个maven的本地路径，例如：F:\\java\\.m2\\repository

2.增加环境变量 M2_REPO ，例如： M2_REPO=F:\\java\\.m2\\repository

3.配置MAVEN_HOME/conf/setting.xml下加入： <localRepository>F:\\java\\.m2\\repository</localRepository>

4.将setting.xml放一份到F:\\java\\.m2\\下。

5.修改eclipase的maven本地仓库： 1.打开myeclipse点击windows->preferences->maven->installations下add一个已经安装到D:\\Java目录下的maven，如：D:\\Java\\maven-3.0.4，并勾选此新加项。并点击下面的browse按钮打开maven的全局配置文件,如：D:\\Java\\maven-3.0.4\\conf\\setting.xml。 2. 打开myeclipse点击windows->preferences->maven->User setting下修改user setting选项为：D:\\Java\\m2\\repository\\settings.xml，并点击update settings。并点击下面的reindex按钮更新索引。

6.运行 mvn help:system验证

maven配置镜像

修改settings.xml文件

<!--
 | 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>F:/Maven/repo/m2/</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. | 
-->
<pluginGroups>
<!--
 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. | 
-->
<proxies>
<!--
<proxy>
			<id>optional</id>
			<active>true</active>
			<protocol>http</protocol>
			<host>127.0.0.1</host>
			<port>8087</port>
		</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. | 
-->
<servers>
<!--
 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> 
-->
</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 | 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>nexus-osc</id>
<mirrorOf>*</mirrorOf>
<name>Nexus osc</name>
<url>http://maven.oschina.net/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>
<!--
 | 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: 
			| | ... | <plugin> | <groupId>org.myco.myplugins</groupId> | <artifactId>myplugin</artifactId> 
			| | <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>

如果可以直接脸上maven官方的中央库就尽量不要配置映射了,因为映射库的jar包总是出问题.
