简单整理一下，方便理解操作。
1、本地拷贝maven文件后，打开maven中的.setting 文件：
2、配置文件：

It can be specified at two levels: 24 | 25 | 1. User Level. This settings.xml file provides configuration for a single user, 26 | and is normally provided in ${user.home}/.m2/settings.xml. 27 | 28 | NOTE: This location can be overridden with the CLI option: 29 | 30 | -s /path/to/user/settings.xml 31 | 32 | 2. Global Level. This settings.xml file provides configuration for all Maven 33 | users on a machine (assuming they're all using the same Maven 34 | installation). It's normally provided in 35 | ${maven.conf}/settings.xml. 36 | 37 | NOTE: This location can be overridden with the CLI option: 38 | 39 | -gs /path/to/global/settings.xml 40 | 41 | The sections in this sample file are intended to give you a running start at 42 | getting the most out of your Maven installation. Where appropriate, the default 43 | values (values used when the setting is not specified) are provided. 44 | 45 |--> 46 <settings xmlns="http://maven.apache.org/SETTINGS/1.0.0" 47 xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" 48 xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd"> 49 <!-- localRepository 50 | The path to the local repository maven will use to store artifacts. 51 | 52 | Default: ${user.home}/.m2/repository --> 53 <localRepository>E:/repository</localRepository> 54 55 56 <!-- interactiveMode 57 | This will determine whether maven prompts you when it needs input. If set to false, 58 | maven will use a sensible default value, perhaps based on some other setting, for 59 | the parameter in question. 60 | 61 | Default: true 62 <interactiveMode>true</interactiveMode> 63 --> 64 65 <!-- offline 66 | Determines whether maven should attempt to connect to the network when executing a build. 67 | This will have an effect on artifact downloads, artifact deployment, and others. 68 | 69 | Default: false 70 <offline>false</offline> 71 --> 72 73 <!-- pluginGroups 74 | This is a list of additional group identifiers that will be searched when resolving plugins by their prefix, i.e. 75 | when invoking a command line like "mvn prefix:goal". Maven will automatically add the group identifiers 76 | "org.apache.maven.plugins" and "org.codehaus.mojo" if these are not already contained in the list. 77 |--> 78 <pluginGroups> 79 <!-- pluginGroup 80 | Specifies a further group identifier to use for plugin lookup. 81 <pluginGroup>com.your.plugins</pluginGroup> 82 --> 83 </pluginGroups> 84 85 <!-- proxies 86 | This is a list of proxies which can be used on this machine to connect to the network. 87 | Unless otherwise specified (by system property or command-line switch), the first proxy 88 | specification in this list marked as active will be used. 89 |--> 90 <proxies> 91 <!-- proxy 92 | Specification for one proxy, to be used in connecting to the network. 93 | 94 <proxy> 95 <id>optional</id> 96 <active>true</active> 97 <protocol>http</protocol> 98 <username>proxyuser</username> 99 <password>proxypass</password> 100 <host>proxy.host.net</host> 101 <port>80</port> 102 <nonProxyHosts>local.net|some.host.com</nonProxyHosts> 103 </proxy> 104 --> 105 </proxies> 106 107 <!-- servers 108 | This is a list of authentication profiles, keyed by the server-id used within the system. 109 | Authentication profiles can be used whenever maven must make a connection to a remote server. 110 |--> 111 <servers> 112 <!-- server 113 | Specifies the authentication information to use when connecting to a particular server, identified by 114 | a unique name within the system (referred to by the 'id' attribute below). 115 | 116 | NOTE: You should either specify username/password OR privateKey/passphrase, since these pairings are 117 | used together. 118 | 119 <server> 120 <id>deploymentRepo</id> 121 <username>repouser</username> 122 <password>repopwd</password> 123 </server> 124 --> 125 126 <!-- Another sample, using keys to authenticate. 127 <server> 128 <id>siteServer</id> 129 <privateKey>/path/to/private/key</privateKey> 130 <passphrase>optional; leave empty if not used.</passphrase> 131 </server> 132 --> 133 </servers> 134 135 <!-- mirrors 136 | This is a list of mirrors to be used in downloading artifacts from remote repositories. 137 | 138 | It works like this: a POM may declare a repository to use in resolving certain artifacts. 139 | However, this repository may have problems with heavy traffic at times, so people have mirrored 140 | it to several places. 141 | 142 | That repository definition will have a unique id, so we can create a mirror reference for that 143 | repository, to be used as an alternate download site. The mirror site will be the preferred 144 | server for that repository. 145 |--> 146 <mirrors> 147 <!-- mirror 148 | Specifies a repository mirror site to use instead of a given repository. The repository that 149 | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used 150 | for inheritance and direct lookup purposes, and must be unique across the set of mirrors. 151 | 152 <mirror> 153 <id>mirrorId</id> 154 <mirrorOf>repositoryId</mirrorOf> 155 <name>Human Readable Name for this Mirror.</name> 156 <url>http://my.repository.com/repo/path</url> 157 </mirror> 158 --> 159 <!--<mirror> 160 <id>alimaven</id> 161 <name>aliyun maven</name> 162 <url>http://maven.aliyun.com/nexus/content/groups/public/</url> 163 //<mirrorOf>central</mirrorOf> 164 <mirrorOf>*</mirrorOf> 165 </mirror>--> 166 167 </mirrors> 168 169 <!-- profiles 170 | This is a list of profiles which can be activated in a variety of ways, and which can modify 171 | the build process. Profiles provided in the settings.xml are intended to provide local machine- 172 | specific paths and repository locations which allow the build to work in the local environment. 173 | 174 | For example, if you have an integration testing plugin - like cactus - that needs to know where 175 | your Tomcat instance is installed, you can provide a variable here such that the variable is 176 | dereferenced during the build process to configure the cactus plugin. 177 | 178 | As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles 179 | section of this document (settings.xml) - will be discussed later. Another way essentially 180 | relies on the detection of a system property, either matching a particular value for the property, 181 | or merely testing its existence. Profiles can also be activated by JDK version prefix, where a 182 | value of '1.4' might activate a profile when the build is executed on a JDK version of '1.4.2_07'. 183 | Finally, the list of active profiles can be specified directly from the command line. 184 | 185 | NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact 186 | repositories, plugin repositories, and free-form properties to be used as configuration 187 | variables for plugins in the POM. 188 | 189 |--> 190 <profiles> 191 <!-- 192 <id>jdk17</id> 193 <activation> 194 <activeByDefault>true</activeByDefault> 195 <jdk>1.7</jdk> 196 </activation> 197 <properties> 198 <maven.compiler.source>1.7</maven.compiler.source> 199 <maven.compiler.target>1.7</maven.compiler.target> 200 <maven.compiler.compilerVersion>1.7</maven.compiler.compilerVersion> 201 </properties> --> 202 <!-- profile 203 | Specifies a set of introductions to the build process, to be activated using one or more of the 204 | mechanisms described above. For inheritance purposes, and to activate profiles via <activatedProfiles/> 205 | or the command line, profiles have to have an ID that is unique. 206 | 207 | An encouraged best practice for profile identification is to use a consistent naming convention 208 | for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc. 209 | This will make it more intuitive to understand what the set of introduced profiles is attempting 210 | to accomplish, particularly when you only have a list of profile id's for debug. 211 | 212 | This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo. 213 <profile> 214 <id>jdk-1.4</id> 215 216 <activation> 217 <jdk>1.4</jdk> 218 </activation> 219 220 <repositories> 221 <repository> 222 <id>jdk14</id> 223 <name>Repository for JDK 1.4 builds</name> 224 <url>http://www.myhost.com/maven/jdk14</url> 225 <layout>default</layout> 226 <snapshotPolicy>always</snapshotPolicy> 227 </repository> 228 </repositories> 229 </profile> 230 --> 231 232 <!-- 233 | Here is another profile, activated by the system property 'target-env' with a value of 'dev', 234 | which provides a specific path to the Tomcat instance. To use this, your plugin configuration 235 | might hypothetically look like: 236 | 237 | ... 238 | <plugin> 239 | <groupId>org.myco.myplugins</groupId> 240 | <artifactId>myplugin</artifactId> 241 | 242 | <configuration> 243 | <tomcatLocation>${tomcatPath}</tomcatLocation> 244 | </configuration> 245 | </plugin> 246 | ... 247 | 248 | NOTE: If you just wanted to inject this configuration whenever someone set 'target-env' to 249 | anything, you could just leave off the <value/> inside the activation-property. 250 | 251 <profile> 252 <id>env-dev</id> 253 254 <activation> 255 <property> 256 <name>target-env</name> 257 <value>dev</value> 258 </property> 259 </activation> 260 261 <properties> 262 <tomcatPath>/path/to/tomcat/instance</tomcatPath> 263 </properties> 264 </profile> 265 --> 266 </profiles> 267 268 <!-- activeProfiles 269 | List of profiles that are active for all builds. 270 | 271 <activeProfiles> 272 <activeProfile>alwaysActiveProfile</activeProfile> 273 <activeProfile>anotherAlwaysActiveProfile</activeProfile> 274 </activeProfiles> 275 --> 276 </settings>
其中两个位置需要注意:本地仓库路径和阿里云maven镜像配置（增加jar包下载速度）
3、Eclipse中配置maven及刚才配置的settings文件。
保存即可。
