title: Java-Eclipse Dependency Errors with Spark
body: <p>So I could be misunderstand how Spark works completely... but here goes.</p>
  
  <p>I am working on a project in (pure) Java, using Eclipse as my IDE. I wanted to use Spark for this, as I have some sections that I need Machine Learning for.
  I tried downloading Spark as provided, but there was no convient jar file I could import, so that didn't work. Trying to import single java files fails completely, since it can't find critical pieces...
  So I learned Maven, and tried downloading Core using Maven, the way listed..</p>
  
  <pre><code>groupId = org.apache.spark
  artifactId = spark-core_2.10
  version = 1.1.0
  </code></pre>
  
  <p>However, my project won't compile because these have dependency issues, and other issues...
  For example, if you import core (like I did), it can't find "Accumulator". This file SHOULD exist, because it's visible on the API (<a href="http://spark.apache.org/docs/latest/api/java/index.html" rel="nofollow">http://spark.apache.org/docs/latest/api/java/index.html</a>), but not anywhere else...</p>
  
  <p>No idea how to proceed, help would be appreciated.</p>
  
  <p>PS: Windows. I'm sorry.</p>
