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>/path/to/local/repo</localRepository> 54 --> 55 <localRepository> 56 D:/apache-maven-3.5.2/repository 57 </localRepository> 58 59 <!-- interactiveMode 60 | This will determine whether maven prompts you when it needs input. If set to false, 61 | maven will use a sensible default value, perhaps based on some other setting, for 62 | the parameter in question. 63 | 64 | Default: true 65 <interactiveMode>true</interactiveMode> 66 --> 67 68 <!-- offline 69 | Determines whether maven should attempt to connect to the network when executing a build. 70 | This will have an effect on artifact downloads, artifact deployment, and others. 71 | 72 | Default: false 73 <offline>false</offline> 74 --> 75 76 <!-- pluginGroups 77 | This is a list of additional group identifiers that will be searched when resolving plugins by their prefix, i.e. 78 | when invoking a command line like "mvn prefix:goal". Maven will automatically add the group identifiers 79 | "org.apache.maven.plugins" and "org.codehaus.mojo" if these are not already contained in the list. 80 |--> 81 <pluginGroups> 82 <!-- pluginGroup 83 | Specifies a further group identifier to use for plugin lookup. 84 <pluginGroup>com.your.plugins</pluginGroup> 85 --> 86 </pluginGroups> 87 88 <!-- proxies 89 | This is a list of proxies which can be used on this machine to connect to the network. 90 | Unless otherwise specified (by system property or command-line switch), the first proxy 91 | specification in this list marked as active will be used. 92 |--> 93 <proxies> 94 <!-- proxy 95 | Specification for one proxy, to be used in connecting to the network. 96 | 97 <proxy> 98 <id>optional</id> 99 <active>true</active> 100 <protocol>http</protocol> 101 <username>proxyuser</username> 102 <password>proxypass</password> 103 <host>proxy.host.net</host> 104 <port>80</port> 105 <nonProxyHosts>local.net|some.host.com</nonProxyHosts> 106 </proxy> 107 --> 108 </proxies> 109 110 <!-- servers 111 | This is a list of authentication profiles, keyed by the server-id used within the system. 112 | Authentication profiles can be used whenever maven must make a connection to a remote server. 113 |--> 114 <servers> 115 <!-- server 116 | Specifies the authentication information to use when connecting to a particular server, identified by 117 | a unique name within the system (referred to by the 'id' attribute below). 118 | 119 | NOTE: You should either specify username/password OR privateKey/passphrase, since these pairings are 120 | used together. 121 | 122 <server> 123 <id>deploymentRepo</id> 124 <username>repouser</username> 125 <password>repopwd</password> 126 </server> 127 --> 128 129 <!-- Another sample, using keys to authenticate. 130 <server> 131 <id>siteServer</id> 132 <privateKey>/path/to/private/key</privateKey> 133 <passphrase>optional; leave empty if not used.</passphrase> 134 </server> 135 --> 136 </servers> 137 138 <!-- mirrors 139 | This is a list of mirrors to be used in downloading artifacts from remote repositories. 140 | 141 | It works like this: a POM may declare a repository to use in resolving certain artifacts. 142 | However, this repository may have problems with heavy traffic at times, so people have mirrored 143 | it to several places. 144 | 145 | That repository definition will have a unique id, so we can create a mirror reference for that 146 | repository, to be used as an alternate download site. The mirror site will be the preferred 147 | server for that repository. 148 |--> 149 <mirrors> 150 <!-- mirror 151 | Specifies a repository mirror site to use instead of a given repository. The repository that 152 | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used 153 | for inheritance and direct lookup purposes, and must be unique across the set of mirrors. 154 | 155 <mirror> 156 <id>mirrorId</id> 157 <mirrorOf>repositoryId</mirrorOf> 158 <name>Human Readable Name for this Mirror.</name> 159 <url>http://my.repository.com/repo/path</url> 160 </mirror> 161 --> 162 <mirror> 163 <id>alimaven</id> 164 <name>aliyun maven</name> 165 <url>http://maven.aliyun.com/nexus/content/groups/public/</url> 166 <mirrorOf>central</mirrorOf> 167 </mirror> 168 169 </mirrors> 170 171 <!-- profiles 172 | This is a list of profiles which can be activated in a variety of ways, and which can modify 173 | the build process. Profiles provided in the settings.xml are intended to provide local machine- 174 | specific paths and repository locations which allow the build to work in the local environment. 175 | 176 | For example, if you have an integration testing plugin - like cactus - that needs to know where 177 | your Tomcat instance is installed, you can provide a variable here such that the variable is 178 | dereferenced during the build process to configure the cactus plugin. 179 | 180 | As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles 181 | section of this document (settings.xml) - will be discussed later. Another way essentially 182 | relies on the detection of a system property, either matching a particular value for the property, 183 | or merely testing its existence. Profiles can also be activated by JDK version prefix, where a 184 | value of '1.4' might activate a profile when the build is executed on a JDK version of '1.4.2_07'. 185 | Finally, the list of active profiles can be specified directly from the command line. 186 | 187 | NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact 188 | repositories, plugin repositories, and free-form properties to be used as configuration 189 | variables for plugins in the POM. 190 | 191 |--> 192 <profiles> 193 <!-- profile 194 | Specifies a set of introductions to the build process, to be activated using one or more of the 195 | mechanisms described above. For inheritance purposes, and to activate profiles via <activatedProfiles/> 196 | or the command line, profiles have to have an ID that is unique. 197 | 198 | An encouraged best practice for profile identification is to use a consistent naming convention 199 | for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc. 200 | This will make it more intuitive to understand what the set of introduced profiles is attempting 201 | to accomplish, particularly when you only have a list of profile id's for debug. 202 | 203 | This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo. 204 <profile> 205 <id>jdk-1.4</id> 206 207 <activation> 208 <jdk>1.4</jdk> 209 </activation> 210 211 <repositories> 212 <repository> 213 <id>jdk14</id> 214 <name>Repository for JDK 1.4 builds</name> 215 <url>http://www.myhost.com/maven/jdk14</url> 216 <layout>default</layout> 217 <snapshotPolicy>always</snapshotPolicy> 218 </repository> 219 </repositories> 220 </profile> 221 --> 222 223 <!-- 224 | Here is another profile, activated by the system property 'target-env' with a value of 'dev', 225 | which provides a specific path to the Tomcat instance. To use this, your plugin configuration 226 | might hypothetically look like: 227 | 228 | ... 229 | <plugin> 230 | <groupId>org.myco.myplugins</groupId> 231 | <artifactId>myplugin</artifactId> 232 | 233 | <configuration> 234 | <tomcatLocation>${tomcatPath}</tomcatLocation> 235 | </configuration> 236 | </plugin> 237 | ... 238 | 239 | NOTE: If you just wanted to inject this configuration whenever someone set 'target-env' to 240 | anything, you could just leave off the <value/> inside the activation-property. 241 | 242 <profile> 243 <id>env-dev</id> 244 245 <activation> 246 <property> 247 <name>target-env</name> 248 <value>dev</value> 249 </property> 250 </activation> 251 252 <properties> 253 <tomcatPath>/path/to/tomcat/instance</tomcatPath> 254 </properties> 255 </profile> 256 --> 257 </profiles> 258 259 <!-- activeProfiles 260 | List of profiles that are active for all builds. 261 | 262 <activeProfiles> 263 <activeProfile>alwaysActiveProfile</activeProfile> 264 <activeProfile>anotherAlwaysActiveProfile</activeProfile> 265 </activeProfiles> 266 --> 267 </settings>
