title: Why am I getting this Maven error?
body: <p>I've been trying to fix this problem for a good part of an hour now, and I haven't gotten anywhere.</p>
  
  <p>When I attempt to compile my project using Maven, I get this error: </p>
  
  <blockquote>
    <p>[ERROR] Failed to execute goal org.apache.maven.plugins:maven-assembly-plugin:2.2-beta-5:single (default-cli) on project GankALane: Unable to parse configuration of mojo org.apache.maven.plugins:maven-assembly-plugin:2.2-beta-5:single for parameter archive: Cannot find setter, adder nor field in org.apache.maven.archiver.MavenArchiveConfiguration for 'descriptorRefs'</p>

  <p>I'm compiling by using the command: 
  <code>mvn clean compile assembly:single</code></p>
  
  <p>and here's my <code>pom.xml</code>:</p>
