<!--
 | 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.
 |
 |-->
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
     xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
     xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
 <!-- localRepository
  | The path to the local repository maven will use to store artifacts.
  |
  | Default: ${user.home}/.m2/repository
  -->
 <localRepository>D:\Maven\repository</localRepository>
 

 <!-- interactiveMode
  | This will determine whether maven prompts you when it needs input. If set to false,
  | maven will use a sensible default value, perhaps based on some other setting, for
  | the parameter in question.
  |
  | Default: true
 <interactiveMode>true</interactiveMode>
 -->

 <!-- offline
  | Determines whether maven should attempt to connect to the network when executing a build.
  | This will have an effect on artifact downloads, artifact deployment, and others.
  |
  | Default: false
 <offline>false</offline>
 -->

 <!-- 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
  | "org.apache.maven.plugins" and "org.codehaus.mojo" if these are not already contained in the list.
  |-->
 <pluginGroups>
  <!-- pluginGroup
   | Specifies a further group identifier to use for plugin lookup.
  <pluginGroup>com.your.plugins</pluginGroup>
  -->
 </pluginGroups>

 <!-- 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.
  |-->
 <proxies>
  <!-- proxy
   | Specification for one proxy, to be used in connecting to the network.
   |
  <proxy>
   <id>optional</id>
   <active>true</active>
   <protocol>http</protocol>
   <username>proxyuser</username>
   <password>proxypass</password>
   <host>proxy.host.net</host>
   <port>80</port>
   <nonProxyHosts>local.net|some.host.com</nonProxyHosts>
  </proxy>
  -->
 </proxies>

 <!-- servers
  | 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>release</id>
   <username>admin</username>
   <password>admin123</password>
  </server>
  
  <server>
   <id>snapshots</id>
   <username>admin</username>
   <password>admin123</password>
  </server>
  
  

  <!-- Another sample, using keys to authenticate.
  <server>
   <id>release</id>
   <privateKey>/path/to/private/key</privateKey>
   <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.
  |-->
 <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>
   <name>Human Readable Name for this Mirror.</name>
   <url>http://my.repository.com/repo/path</url>
  </mirror>
   -->
 </mirrors>

 <!-- 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>
    </property>
   </activation>
