      | 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.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.

       <!-- 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.
        |-->
       <mirrors>
         <!-- mirror
          | Specifies a repository mirror site to use instead of a given repository. The repository that
          | this mirror serves has an ID that matches the mirrorOf element of this mirror. IDs are used
          | for inheritance and direct lookup purposes, and must be unique across the set of mirrors.
          |
         <mirror>
           <id>mirrorId</id>
           <mirrorOf>repositoryId</mirrorOf>

       <!-- 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.
        |
        |-->
       <profiles>
         <!-- profile
          | Specifies a set of introductions to the build process, to be activated using one or more of the
          | mechanisms described above. For inheritance purposes, and to activate profiles via <activatedProfiles/>
          | or the command line, profiles have to have an ID that is unique.
          |
          | An encouraged best practice for profile identification is to use a consistent naming convention
          | for profiles, such as 'env-dev', 'env-test', 'env-production', 'user-jdcasey', 'user-brett', etc.
          | This will make it more intuitive to understand what the set of introduced profiles is attempting
          | to accomplish, particularly when you only have a list of profile id's for debug.
          |
          | This profile example uses the JDK version to trigger activation, and provides a JDK-specific repo.
         <profile>
           <id>jdk-1.4</id>
           <activation>
             <jdk>1.4</jdk>
           </activation>
           <repositories>
             <repository>
               <id>jdk14</id>
               <name>Repository for JDK 1.4 builds</name>
               <url>http://www.myhost.com/maven/jdk14</url>
               <layout>default</layout>
               <snapshotPolicy>always</snapshotPolicy>
             </repository>
           </repositories>
         </profile>
         -->
         <!--
          | Here is another profile, activated by the system property 'target-env' with a value of 'dev',
          | which provides a specific path to the Tomcat instance. To use this, your plugin configuration
          | might hypothetically look like:
          |
          | ...
          | <plugin>
          |   <groupId>org.myco.myplugins</groupId>
          |   <artifactId>myplugin</artifactId>
          |
          |   <configuration>
          |     <tomcatLocation>${tomcatPath}</tomcatLocation>
          |   </configuration>
          | </plugin>
          | ...
          |
          | NOTE: If you just wanted to inject this configuration whenever someone set 'target-env' to
          |       anything, you could just leave off the <value/> inside the activation-property.
          |
         <profile>
           <id>env-dev</id>
           <activation>
             <property>
               <name>target-env</name>
               <value>dev</value>

             <tomcatPath>/path/to/tomcat/instance</tomcatPath>
