title: Could not resolve dependencies ... until the update interval has elapsed or updates are forced
body: <p>While trying to compile Jena, I met the following error:</p>
  
  <pre><code>[ERROR] Failed to execute goal on project jena-elephas-stats: Could not resolve dependencies for project org.apache.jena:jena-elephas-stats:jar:3.1.1-SNAPSHOT: Failure to find org.apache.jena:jena-ele
  phas-mapreduce:jar:tests:3.1.1-SNAPSHOT in https://repository.apache.org/snapshots was cached in the local repository, resolution will not be reattempted until the update interval of apache.snapshots
  has elapsed or updates are forced -&gt; [Help 1]
  </code></pre>
  
  <p>What does it mean? What was cached and where? How to force update?</p>
