title: SLF4J Binding Error
body: <p>Im am new to maven and the last two days i try to integrate maven into a small web project.
  (I use Eclipse Juno as IDE). 
  First I generated a new project (structure) with the "mvn-archetype-webapp" command and copied the sources from the project into this structure. 
  Then I added all dependencies to the pom.xml so that I could compile and start the project with the tomcat7 plugin. 
  So far everything works fine except the SLF4J Error Messages at the start of every maven command: </p>
  
   <pre class="lang-java prettyprint-override"><code>    SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder". 
      SLF4J: Defaulting to no-operation (NOP) logger implementation SLF4J:
      See http://www.slf4j.org/codes.html#StaticLoggerBinder for further details.
  </code></pre>
  
  <p>My pom.xml dependencies looks like this:</p>
