+ | 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.

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

+  <localRepository>/path/to/local/repo</localRepository>
+  -->
+
+  <!-- interactiveMode
+   | This will determine whether maven prompts you when it needs input. If set to false,

+  -->
+
+  <!-- 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

+  <!-- 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.

+   | 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>

+      <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.
+   |-->
+
+  <!-- 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.
