title: Maven refuse to download aar packaged dependency from remote repository
body: <p>I want to use this android dependency in my java program:</p>
  
  <pre><code>http://jcenter.bintray.com/com/o3dr/android/dronekit-android/2.9.0/
  </code></pre>
  
  <p>so I added all the plugins &amp; repositories into my maven pom file:</p>
  
  <pre><code>&lt;repositories&gt;
      &lt;repository&gt;
          &lt;id&gt;central&lt;/id&gt;
          &lt;name&gt;bintray&lt;/name&gt;
          &lt;url&gt;http://jcenter.bintray.com&lt;/url&gt;
          &lt;!--&lt;snapshots&gt;--&gt;
              &lt;!--&lt;enabled&gt;false&lt;/enabled&gt;--&gt;
          &lt;!--&lt;/snapshots&gt;--&gt;
      &lt;/repository&gt;
  &lt;/repositories&gt;
  
  &lt;pluginRepositories&gt;
      &lt;pluginRepository&gt;
          &lt;!--&lt;snapshots&gt;--&gt;
              &lt;!--&lt;enabled&gt;false&lt;/enabled&gt;--&gt;
          &lt;!--&lt;/snapshots&gt;--&gt;
          &lt;id&gt;central&lt;/id&gt;
          &lt;name&gt;bintray-plugins&lt;/name&gt;
          &lt;url&gt;http://jcenter.bintray.com&lt;/url&gt;
      &lt;/pluginRepository&gt;
  &lt;/pluginRepositories&gt;
  
  &lt;build&gt;
      &lt;plugins&gt;
          &lt;plugin&gt;
              &lt;groupId&gt;com.simpligility.maven.plugins&lt;/groupId&gt;
              &lt;artifactId&gt;android-maven-plugin&lt;/artifactId&gt;
              &lt;version&gt;4.1.0&lt;/version&gt;
  
              &lt;extensions&gt;true&lt;/extensions&gt;
              &lt;configuration&gt;
                  &lt;sign&gt;
                      &lt;debug&gt;false&lt;/debug&gt;
                  &lt;/sign&gt;
              &lt;/configuration&gt;
          &lt;/plugin&gt;
          ...
  </code></pre>
  
  <p>Then I add the dependency into the same file:</p>
  
  <pre><code>    &lt;dependency&gt;
          &lt;groupId&gt;com.o3dr.android&lt;/groupId&gt;
          &lt;artifactId&gt;dronekit-android&lt;/artifactId&gt;
          &lt;version&gt;2.9.0&lt;/version&gt;
          &lt;type&gt;aar&lt;/type&gt;
      &lt;/dependency&gt;
  </code></pre>
  
  <p>But nothing happens, maven ignore it as if it doesn't exist, if I import its main package in a scala file and build it with <code>mvn clear install -U</code>, I get this error:</p>
  
  <blockquote>
    <p>[ERROR] /home/peng/git-drone/dronespike/src/main/scala/Main.scala:1: object o3dr is not a member of package com<br>
    [ERROR] import com.o3dr.android._<br>
    [ERROR]            ^</p>
  </blockquote>
  
  <p><strong>Question</strong>: What should I do to fix this problem?</p>
