1. Install SLF4J Logging :
Eclipse –> Help –> Install New Software
Work with: http://www.fuin.org/p2-repository/
Click “Add”
Select Slf4j-api under Maven osgi-bundles
Click “Next”

Eclipse –> Help –> Install New Software
http://guava-osgi.googlecode.com/svn/trunk/repository/

Maven 1.5 seems have problem with Eclipse 3.8
Eclipse –> Help –> Install New Software
http://download.eclipse.org/technology/m2e/releases
Uncheck “Show only the latest versions of available software”
Choose version 1.4
4 . Import the existing Maven project:
File –> Import –> …
