  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">

 [[3]] Apache DAV passwords

+-------------
 Add the following info into your ~/.netrc
 machine git-wip-us.apache.org login <apache username> <password>

 [[4]] Release Helix

    You should have a GPG agent running in the session you will run the maven release commands (preferred), and confirm it works by running "gpg -ab" (type some text and press Ctrl-D).
    If you do not have a GPG agent running, make sure that you have the "apache-release" profile set in your settings.xml as shown below.


  GPG configuration in maven settings (~/.m2/settings.xml):

+-------------
<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">
  <!-- ... -->
  <profiles>
    <profile>
      <id>apache-release</id>
      <properties>
        <gpg.passphrase>[GPG_PASSWORD]</gpg.passphrase>
      </properties>
    </profile>
  </profiles>
  <!-- ... -->
</settings>
+-------------
   Before release please make sure <<maven-release-plugin version>> in <pom.xml> is <<2.5.1>> or <<newer>>.
