title: Error in grabbing Grapes - Dependency not found
body: <p>I have a Groovy file having following code :</p>
  <pre><code>@Grab(group='org.codehaus.groovy.modules.http-builder', module='http-builder', version='0.7' )
  </code></pre>
  <p>I am trying to download the dependencies to use <code>HTTPBuilder</code>.</p>
  <p>But it's showing me the error as follows :</p>
  <blockquote>
  <p>Error grabbing Grapes -- [download failed: org.apache.httpcomponents#httpclient;4.2.1!httpclient.jar,download failed: org.apache.httpcomponents#httpcore;4.2.1!httpcore.jar, download failed: commons-codec#commons-codec;1.6!commons-codec.jar, download failed: commons-beanutils#commons-beanutils;1.8.0!commons-beanutils.jar, download failed: commons-lang#commons-lang;2.4!commons-lang.jar]</p>

  <p>I tried resolving this Grape dependency using below command in command prompt :</p>
  <pre><code>grape resolve org.codehaus.groovy.modules.http-builder http-builder 0.7.2
  </code></pre>
  <p>I also tried the below one too :</p>
  <pre><code>grape install org.codehaus.groovy.modules.http-builder http-builder 0.7.2
  </code></pre>
  <p>then also it is showing me the same error. How can I solve this problem? I use Groovy version 2.2.2.</p>
