title: Why doesn't mvn dependency:purge-local-repository fetch the same dependencies as mvn install does?
body: <p>I don't understand why an errors occurs when I invoke <code>mvn dependency:purge-local-repository -DreResolve=true</code> and it doesn't when I invoke <code>mvn install</code>. I experienced failures of <code>dependency:purge-local-repository</code>, but sucess of <code>mvn install</code>? How could this happen if the build succeeded once (i.e. all dependencies could be fetched from somewhere), but not in re-resolution of <code>dependency:purge-local-repository</code>. Do I suffer from a general misunderstanding?</p>
  
  <p>Issues occured with maven 3.2.2.</p>
