To add the client as a Maven 2 dependency, first you'll need to add the BLC repository to your POM:
<repositories>
...
<repository>
<id>BLC</id>
<name>BLC</name>
<url>http://nexus.blueleftistconstructor.com/content/repositories/releases</url>
</repository>
...
</repositories>
...and then add the following dependency:
<dependencies>
...
<dependency>
<groupId>com.lysergicjava.nfclient</groupId>
<artifactId>netflix-java-client</artifactId>
<version>2.1.2</version>
</dependency>
...
</dependencies>
Download the client here. Then, all you need to do is add the netflix-java-client.jar to your project's classpath. Just import com.netflix.api.client.NetflixAPIClient when needed.
First, you'll need to get the source, which is hosted in a Mercurial repository. Once you have a Mercurial client installed, just run hg clone http://www.blueleftistconstructor.com/hg/nfjc to pull the complete project. You'll then need Maven 2.0.8 or greater to build the client. Just run mvn clean package and you're good to go.
