To deploy a site to a Nexus Professional Maven Site repository, you will need to configure the project's distribution management settings, add site deployment information, and then update your Maven settings to include the appropriate credentials for Nexus.

~/examples$ cd sample-site
~/examples/sample-site$ more pom.xml
<project xmlns="http://maven.apache.org/POM/4.0.0" 
         xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
         xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 
                             http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>org.sonatype.books.nexus</groupId>
  <artifactId>sample-site</artifactId>
  <packaging>jar</packaging>
  <version>1.0-SNAPSHOT</version>
  <name>sample-site</name>
  <url>http://maven.apache.org</url>
  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>3.8.1</version>
      <scope>test</scope>
    </dependency>
  </dependencies>
</project>

Add the following section to sample-site/pom.xml after the dependencies element. This section will tell Maven where to publish the Maven-generated project web site:

  <distributionManagement>
    <site>
      <id>nexus-site</id>
      <url>dav:http://localhost:8081/nexus/content/sites/site/</url>
    </site>
  </distributionManagement>

In addition to the distributionManagement element, you will want to add the following build element that will configure Maven to use version 2.0.1 of the Maven Site plugin.

  <build>
    <plugins>
      <plugin>
        <artifactId>maven-site-plugin</artifactId>
        <version>2.0.1</version>
      </plugin>
    </plugins>
  </build>
