title: Sbt proxy configuration problems
body: <p>So, it seems that I have a problem configuring proxy for SBT. I tried the following methods</p>
  
  <ol>
  <li><p>Configured the following parameters in %SBT_HOME%\conf\stbconfig.txt:</p>
  
  <pre><code>-Dhttp.proxySet=true 
  -Dhttp.proxyHost=proxy_server
  -Dhttp.proxyPort=proxy_port 
  -Dhttp.nonProxyHosts="localhost|127.0.0.1" 
  -Dhttp.proxyUser=username
  -Dhttp.proxyPassword=password
  -Dhttps.proxyHost=proxy_server
  -Dhttps.proxyPort=proxy_port 
  -Dhttps.nonProxyHosts="localhost|127.0.0.1" 
  -Dhttps.proxyUser=username
  -Dhttps.proxyPassword=password
  </code></pre></li>
  <li><p>I added the above parameters sbtopts file but didn't work.</p></li>
  <li><p>I tried the solutions that said to pass the configurations in command line as environment variables ( JAVA_OPTS or SBT_OPTS) but it seems that it didn't worked for me. </p></li>
  </ol>
  
  <p>I still got errors( Unresolved dependencies) and/or warnings ( [warn] Your proxy requires authentication.)</p>
  
  <p>I use java 1.8.0_131 and sbt 1.0.2. Scala version is:  2.12.3.</p>
  
  <p>The output of the <strong>sbt new scala/hello-world.g8</strong> is:</p>
