title: Can't update build.gradle to use support library 23.0.1
body: <p>So I've updated my build.gradle file:</p>
  
  <pre><code>compile 'com.android.support:appcompat-v7:23.0.1'
  compile 'com.android.support:recyclerview-v7:23.0.1'
  compile 'com.android.support:cardview-v7:23.0.1'
  compile 'com.android.support:design:23.0.1'
  </code></pre>
  
  <p>But when I try to sync the project this pops up</p>
  
  <pre><code>Error:(25, 13) Failed to resolve: com.android.support:recyclerview-v7:23.0.1
  Install Repository and sync project
  Show in File
  Show in Project Structure dialog
  </code></pre>
  
  <p>(and the same for the other two repositories)</p>
  
  <p>Then I try to click "Install Repository and sync project" and this error occurs:</p>
  
  <pre><code>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 install fails.</p>
  
  <p>I have installed build tools 23.0.1 and everything for android M in SDK manager.
  Tried rolling back to 23.0.0 but it's the same. </p>
  
  <p>What's wrong? Where did this package filter came from? I dont think I changed anything except for build.gradle before this error occured</p>
  
  <p>EDIT: I tried to delete build tools and install them again and while installing SDK manager log popped up with this:</p>
  
  <pre><code>Preparing to install archives
