title: StanfordCoreNLP compiler errors using javac
body: <p>I have just started looking into the Stanford NLP libraries. I downloaded and uncompressed the core file that includes everything, then tried to run the demo file (StanfordCoreNlpDemo.java).</p>
  
  <pre><code>import edu.stanford.nlp.io.*;
  import edu.stanford.nlp.ling.*;
  import edu.stanford.nlp.pipeline.*;
  import edu.stanford.nlp.semgraph.SemanticGraph;
  import edu.stanford.nlp.semgraph.SemanticGraphCoreAnnotations;
  import edu.stanford.nlp.trees.*;
  import edu.stanford.nlp.util.*;
  </code></pre>
  
  <p>All of the import lines trigger an "error: package edu.stanford.nlp. does not exist" message. </p>
  
  <p>Can anyone tell me what I need to do to make the demo work?</p>
