 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.

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.

149      | Specifies a repository mirror site to use instead of a given repository. The repository that

194   <!-- profiles
195    | This is a list of profiles which can be activated in a variety of ways, and which can modify
196    | the build process. Profiles provided in the settings.xml are intended to provide local machine-
197    | specific paths and repository locations which allow the build to work in the local environment.
198    |
199    | For example, if you have an integration testing plugin - like cactus - that needs to know where
200    | your Tomcat instance is installed, you can provide a variable here such that the variable is
201    | dereferenced during the build process to configure the cactus plugin.
202    |
203    | As noted above, profiles can be activated in a variety of ways. One way - the activeProfiles
204    | section of this document (settings.xml) - will be discussed later. Another way essentially
205    | relies on the detection of a system property, either matching a particular value for the property,
206    | or merely testing its existence. Profiles can also be activated by JDK version prefix, where a
207    | value of ‘1.4‘ might activate a profile when the build is executed on a JDK version of ‘1.4.2_07‘.
208    | Finally, the list of active profiles can be specified directly from the command line.
209    |
210    | NOTE: For profiles defined in the settings.xml, you are restricted to specifying only artifact
211    |       repositories, plugin repositories, and free-form properties to be used as configuration
212    |       variables for plugins in the POM.
213    |
214    |-->
215   <profiles>
216     <!-- profile
217      | Specifies a set of introductions to the build process, to be activated using one or more of the
218      | mechanisms described above. For inheritance purposes, and to activate profiles via <activatedProfiles/>
219      | or the command line, profiles have to have an ID that is unique.
220      |
221      | An encouraged best practice for profile identification is to use a consistent naming convention
222      | for profiles, such as ‘env-dev‘, ‘env-test‘, ‘env-production‘, ‘user-jdcasey‘, ‘user-brett‘, etc.
223      | This will make it more intuitive to understand what the set of introduced profiles is attempting
224      | to accomplish, particularly when you only have a list of profile id‘s for debug.
225      |
226      | This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo.
227     <profile>
228       <id>jdk-1.4</id>

230       <activation>

243     </profile>
244     -->
245 
246     <!--
247      | Here is another profile, activated by the system property ‘target-env‘ with a value of ‘dev‘,
248      | which provides a specific path to the Tomcat instance. To use this, your plugin configuration
249      | might hypothetically look like:
250      |
251      | ...
252      | <plugin>
253      |   <groupId>org.myco.myplugins</groupId>

258      |   </configuration>
259      | </plugin>
260      | ...
261      |
262      | NOTE: If you just wanted to inject this configuration whenever someone set ‘target-env‘ to
263      |       anything, you could just leave off the <value/> inside the activation-property.
