title: Android Studio: appcompat installation fails
body: <p>I've a strange problem. I just installed the most recent version of android studio and created a plain vanilla blank activity application. After that, when the IDE opens it tries to install <code>com.android.support:appcompat-v7:14+</code>. However, then I get the error message:</p>
  
  <pre><code>Failed to resolve: com.android.support:appcompat-v7:14+
  Install repository and sync project
  </code></pre>
  
  <p>So, I click on <code>Install repository and sync project</code> however, then I get the following error message:</p>
  
  <pre><code>Loading SDK information...
  Ignoring unknown package filter 'extra-android-m2repository'Warning: The package filter removed all packages. There is nothing to install.
              Please consider trying to update again without a package filter.
  </code></pre>
  
  <p>And underneth it red it is stated:</p>
  
  <pre><code>Install Failed. Please check your network connection and try again. You may continue with creating you project, but it will not compile correctly without the missing components.
  </code></pre>
  
  <p>So, my internet connection is perfectly fine, no traffic gets block by an firewall or something.</p>
  
  <p>What is wrong here? Are there alternatives for installing <code>com.android.support:appcompat-v7:14+</code>?</p>
