+    If one of your repos requires basic authentication, you can supply its credentials
+    in your <code>local.properties</code> file by specifying keys and values following the format:
+</p>
+<pre>
+authUrl.{host}.username=xxx
+authUrl.{host}.password=xxx
+</pre>
+<p>
+  Note that the host is just the host name portion of the URL (excluding "http://",
+  port number, slash and path). For example, for the repo
+  <code>"https://dl.bintray.com/cbeust/maven/"</code>, the credentials would be:
+</p>
+<pre>
+authUrl.dl.bintray.com.username=xxx
+authUrl.dl.bintray.com.password=xxx
+</pre>

+  If only one of <code>username</code> or <code>password</code> is specified,
