title: How to run Spark-shell including sansa-stack library for loading rdf File
body: <p>I'm trying to run spark-shell including the sansa-stack library for loading rdf data.
  I run the comand:</p>
  
  <pre><code>./spark-2.2.0-bin-hadoop2.7/bin/spark-shell --packages net.sansa-stack:sansa-rdf-parent_2.11:0.3.1-SNAPSHOT
  </code></pre>
  
  <p>the I get this log:</p>
  
  <pre><code>Ivy Default Cache set to: /home/xitan/.ivy2/cache
  The jars for the packages stored in: /home/xitan/.ivy2/jars
  :: loading settings :: url = jar:file:/home/xitan/Documenti/sparkin/spark-2.2.0-bin-hadoop2.7/jars/ivy-2.4.0.jar!/org/apache/ivy/core/settings/ivysettings.xml
  net.sansa-stack#sansa-rdf-parent_2.11 added as a dependency
  :: resolving dependencies :: org.apache.spark#spark-submit-parent;1.0
      confs: [default]
      found net.sansa-stack#sansa-rdf-parent_2.11;0.3.1-SNAPSHOT in local-m2-cache
  </code></pre>
  
  <p>after that I get the spark-shell, but when I try to import a function from sansa-stack it gives me an error</p>
  
  <pre><code>scala&gt; import net.sansa_stack.rdf.spark.io.NtripleReader
  </code></pre>
  
  <p>it does not find the library:</p>
  
  <pre><code>&lt;console&gt;:23: error: object sansa_stack is not a member of package net
         import net.sansa_stack.rdf.spark.io.NtripleReader
  </code></pre>
