title: Gradle can't resolve dependencies through my http proxy
body: <p>when I try to run <code>gradle dependencies</code> on my computer I am getting a 407 status code "Proxy Authentication Required."</p>
  
  <p>I created a gradle.properties file in my <code>%GRADLE_HOME%</code> directory.  <code>gradle.properties</code> contains the following entries:</p>
  
  <pre><code>systemProp.proxySet='true'
  systemProp.http.proxyHost=http-proxy.nwie.net
  systemProp.http.proxyPort=8080
  systemProp.http.proxyUser=%myUserNameHere%
  systemProp.http.proxyPassword=%myPasswordHere%
  </code></pre>
  
  <p>I can successfully get through my proxy for ruby gems by setting HTTP_PROXY to the following value:
  <a href="http://%myUserNameHere%:%myPasswordHere%@http-proxy.nwie.net:8080" rel="noreferrer">http://%myUserNameHere%:%myPasswordHere%@http-proxy.nwie.net:8080</a></p>
  
  <p>I am using gradle-1.3, please let me know if there is something I am missing.</p>
  
  <p>Thanks in advance!</p>
  
  <p>UPDATE:
  I tried setting systemProp.http.proxyUser to a new value in domain/username format.  Below are my current properties file contents:</p>
  
  <pre><code>systemProp.proxySet=true
  systemProp.http.proxyHost=http-proxy.nwie.net
  systemProp.http.proxyPort=8080
  systemProp.http.proxyUser=http-proxy.nwie.net/%USERNAME%
  systemProp.http.proxyPassword=%PASSWORD%
  </code></pre>
  
  <p>I am currently getting the same error message I found initially.</p>
