title: svn command fail from Maven
body: <p>I have imported a project with Maven that has a module using STP-SCA Tools. The <a href="http://websvn.ow2.org/filedetails.php?repname=frascati&amp;path=/trunk/org.eclipse.stp.sca.model/pom.xml" rel="nofollow">POM</a> of this module tries to download the STP-SCA Tools by SVN.</p>
  
  <p>When I do a <code>mvn install</code> of this <code>POM.xml</code> I get the following on cmd</p>
  
  <pre><code>[INFO]

  <p>If I try that svn dir on Eclipse it works.</p>
  
  <p>Why does the svn command fail from Maven?</p>
