Installation

Configuration

Windows:

C:\> mkdir c:\Documents and Settings\<your_username>\.m2
C:\> copy "c:\Program Files\apache-maven-2.1.0\conf\settings.xml" "c:\Documents and Settings\<your_username>\.m2\"
        1 file(s) copied.

Configuration at a "Global Level" (for all users on a machine) can be done in "${maven.home}/conf/settings.xml"

Local Repository

The location of your local repository can be changed in your user configuration ("${user.home}/.m2/settings.xml").
The default value is "${user.home}/.m2/repository/" (= "~/.m2/repository").

<settings>
 ...
 <localRepository>C:/Documents and Settings/<your_username>/.m2/repository</localRepository>
 ...
</settings>

Note: The local repository must be an absolute path.

HTTP Proxy

You can configure a proxy to use for some or all of your HTTP requests in Maven 2.0. The username and password are only required if your proxy requires basic authentication (note that later releases may support storing your passwords in a secured keystore - in the mean time, please ensure your settings.xml file (usually ${user.home}/.m2/settings.xml) is secured with permissions appropriate for your operating system).
The nonProxyHosts setting accepts wild cards, and each host not to proxy is separated by the | character. This matches the JDK configuration equivalent.

<settings>
      ...
      <proxies>
            <proxy>
                  <id>_location name_</id>
                  <active>true</active>
                  <protocol>http</protocol>
                  <host>_internal proxy address_</host>
                  <port>_proxy port_</port>
                  <username>{your_proxyuser}</username>
                  <password>{your_proxypassword}</password>
                  <nonProxyHosts>localhost</nonProxyHosts>
          </proxy>
      </proxies>
      ...
</settings>

Using an intranet mirror repository

Behind the firewall of a company's network it is useful to set up a central repository mirror server (e.g. opensource product "Archiva").

<mirrors>
 ...
 <mirror>
    <id>archiva.central</id>
    <mirrorOf>central</mirrorOf>
    <name>Archiva mirror of central Maven repository.</name>
    <url>http://_server_address_and_port_/archiva/repository/internal/</url>
 </mirror>
 ...
</mirrors>

Test

Windows:

C:\>mvn
[INFO] Scanning for projects...

[ERROR] BUILD FAILURE

[INFO]
 
You must specify at least one goal or lifecycle phase to perform build steps.
The following list illustrates some commonly used build commands:
 
 mvn clean
    Deletes any build output (e.g. class files or JARs).
 mvn test
    Runs the unit tests for the project.
 mvn install
    Copies the project artifacts into your local repository.
 mvn deploy
    Copies the project artifacts into the remote repository.
 mvn site
    Creates project documentation (e.g. reports or Javadoc).
 
Please see
http://maven.apache.org/guides/introduction/introduction-to-the-lifecycle.html
for a complete description of available lifecycle phases.
 
Use "mvn --help" to show general usage information about Maven's command line.

This behaviour is ok, because maven does not find a pom.xml file to process and you didn't specify a goal.

Windows:
