title: Errors in pom.xml with dependencies (Missing artifact...)
body: <p>A friend has passed me a Maven project that I'm trying to run locally in my computer. All that I have done in Eclipse, I selected:</p>
  
  <blockquote>
    <p>File -> Import -> Existing Maven Projects</p>
  </blockquote>
  
  <p>After that, the project showed me 4 errors in my <code>pom.xml</code> (Missing artifact..):</p>

  <p>I tried removing the content of <code>.m2</code> folder and then in Eclipse I clicked on my project and chose "Run as" -> "Maven clean" and then "Run as" -> "Maven install". But I still have the same errors. I'm new with Spring so I dont know what else to do.</p>
  
  <p>EDIT:</p>
  
  <p>When I try to do: run as/ maven install, this is what my console says:</p>

  <p>EDIT2: This is my complete pom.xml: <a href="https://dl.dropboxusercontent.com/u/31349296/pom.xml">https://dl.dropboxusercontent.com/u/31349296/pom.xml</a> It looks pretty awful when I try to paste the code here.</p>
