title: Groovy - Grab - download failed
body: <p>I have a fresh installation of Groovy 2.1.4 and I'd like to create a script that uses HTTP builder.</p>
  
  <p>I've added the following line at the top of the script:</p>
  
  <pre><code>@Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.6')
  </code></pre>
  
  <p>When I run the script in GroovyConsole, I get the following error:</p>
  
  <pre><code>1 compilation error:
  
  Exception thrown

  <pre><code>grape -V resolve org.codehaus.groovy.modules.http-builder http-builder 0.6
  </code></pre>
  
  <p>I get the same error, i.e.:</p>

  Error in resolve:
      Error grabbing Grapes -- [download failed: commons-logging#commons-logging;1.1.1!commons-logging.jar]
  </code></pre>
  
  <p>When I try to resolve commons-logging directly, via the following command:</p>
  
  <pre><code>grape -V resolve commons-logging commons-logging 1.1.1
  </code></pre>
  
  <p>I get the same error, i.e. <code>not found</code>.</p>
  
  <p>When I instead try to download the latest version, i.e. 1.1.3, via the appropriate command, it works. But even after that, resolving the http-client still fails.</p>
  
  <p>Where's the problem?</p>
