23 | This is the configuration file for Maven. 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"

49   <!--localRepository
50 | The path to the local repository maven will use to store artifacts.

55   <localRepository>d:/maven/repository</localRepository>
56 
57   <!--interactiveMode
58 | This will determine whether maven prompts you when it needs input. If set to false,
59 | maven will use a sensible default value, perhaps based on some other setting, for
60 | the parameter in question.
61 |
62 | Default: true
63 <interactiveMode>true</interactiveMode>

65 
66   <!--offline
67 | Determines whether maven should attempt to connect to the network when executing a build.
68 | This will have an effect on artifact downloads, artifact deployment, and others.
69 |
70 | Default: false
71 <offline>false</offline>
72   -->
73 
74   <!--pluginGroups
75 | This is a list of additional group identifiers that will be searched when resolving plugins by their prefix, i.e.
76 | when invoking a command line like "mvn prefix:goal". Maven will automatically add the group identifiers
77 | "org.apache.maven.plugins" and "org.codehaus.mojo" if these are not already contained in the list.
78 |-->
79   <pluginGroups>
80     <!--pluginGroup
81 | Specifies a further group identifier to use for plugin lookup.
82 <pluginGroup>com.your.plugins</pluginGroup>
83     -->
84   </pluginGroups>
85 
86   <!--proxies
87 | This is a list of proxies which can be used on this machine to connect to the network.
88 | Unless otherwise specified (by system property or command-line switch), the first proxy
89 | specification in this list marked as active will be used.
90 |-->

93 | Specification for one proxy, to be used in connecting to the network.

108   <!--servers
109 | This is a list of authentication profiles, keyed by the server-id used within the system.
110 | Authentication profiles can be used whenever maven must make a connection to a remote server.
111 |-->
112   <servers>
113     <!--server
114 | Specifies the authentication information to use when connecting to a particular server, identified by
115 | a unique name within the system (referred to by the 'id' attribute below).
116 |
117 | NOTE: You should either specify username/password OR privateKey/passphrase, since these pairings are
118 |       used together.
119 |
120 <server>
121 <id>deploymentRepo</id>
122 <username>repouser</username>

134   </servers>
135 
136   <!--mirrors
137 | This is a list of mirrors to be used in downloading artifacts from remote repositories.
138 |
139 | It works like this: a POM may declare a repository to use in resolving certain artifacts.
140 | However, this repository may have problems with heavy traffic at times, so people have mirrored
141 | it to several places.
142 |
143 | That repository definition will have a unique id, so we can create a mirror reference for that
144 | repository, to be used as an alternate download site. The mirror site will be the preferred
145 | server for that repository.
146 |-->
147   <mirrors>
148     <!--mirror
149 | Specifies a repository mirror site to use instead of a given repository. The repository that
150 | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
151 | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
152 |
153 <mirror>
154 <id>mirrorId</id>
155 <mirrorOf>repositoryId</mirrorOf>
156 <name>Human Readable Name for this Mirror.</name>

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     <!--profile
192 | Specifies a set of introductions to the build process, to be activated using one or more of the
193 | mechanisms described above. For inheritance purposes, and to activate profiles via <activatedProfiles/>
194 | or the command line, profiles have to have an ID that is unique.
195 |
196 | An encouraged best practice for profile identification is to use a consistent naming convention
197 | for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc.
198 | This will make it more intuitive to understand what the set of introduced profiles is attempting
199 | to accomplish, particularly when you only have a list of profile id's for debug.
200 |
201 | This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo.
202 <profile>
203 <id>jdk-1.4</id>
204 
205 <activation>
206 <jdk>1.4</jdk>
207 </activation>
208 
209 <repositories>
210 <repository>
211 <id>jdk14</id>
212 <name>Repository for JDK 1.4 builds</name>
213 <url>http://www.myhost.com/maven/jdk14</url>
214 <layout>default</layout>
215 <snapshotPolicy>always</snapshotPolicy>
216 </repository>
217 </repositories>
218 </profile>
219     -->
220 
221     <!--
222 | Here is another profile, activated by the system property 'target-env' with a value of 'dev',
223 | which provides a specific path to the Tomcat instance. To use this, your plugin configuration
224 | might hypothetically look like:
225 |
226 | ...
227 | <plugin>
228 |   <groupId>org.myco.myplugins</groupId>
229 |   <artifactId>myplugin</artifactId>
230 |
231 |   <configuration>
232 |     <tomcatLocation>${tomcatPath}</tomcatLocation>
233 |   </configuration>
234 | </plugin>
235 | ...
236 |
237 | NOTE: If you just wanted to inject this configuration whenever someone set 'target-env' to
238 |       anything, you could just leave off the <value/> inside the activation-property.
239 |
