title: Got "undefined method `[]' for nil:NilClass" installing java Cookbook
body: <p>I try to set up a vagrant vm using Chef Solo and Berkshelf. I want to use the <a href="https://github.com/opscode-cookbooks/java" rel="nofollow">maven</a> cookbook. "maven" depends on "java" and "java_ark" (which is included in the "java" cookbook). All of them were created by Opscode.</p>
  
  <p>But everytime I get this error:</p>
  
  <pre><code>NoMethodError
  
  -------------
  
  undefined method `[]' for nil:NilClass
