title: Gradle build: file not found error
body: <p>I'm running into this error when I try to build my project with Gradle:</p>
  
  <pre><code>${path_to_project}\teacher\build\intermediates\incremental\mergeDebugAndroidTestResources\merged.dir\values-w270dp-h560dp-v13\values-w270dp-h560dp-v13.xml: error: file not found.
  </code></pre>
  
  <p>I'm really confused because I opened the file and it seems like it's from a dependecy I'm using: <code>com.wdullaer:materialdatetimepicker:3.4.1</code></p>
  
  <p>Here's the xml file:</p>
  
  <pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
  &lt;resources&gt;
      &lt;dimen name="mdtp_selected_calendar_layout_height"&gt;230dp&lt;/dimen&gt;
      &lt;dimen name="mdtp_selected_date_day_size"&gt;100dp&lt;/dimen&gt;
      &lt;dimen name="mdtp_selected_date_height"&gt;190dp&lt;/dimen&gt;
      &lt;dimen name="mdtp_selected_date_month_size"&gt;30dp&lt;/dimen&gt;
      &lt;dimen name="mdtp_selected_date_year_size"&gt;30dp&lt;/dimen&gt;
  &lt;/resources&gt;
  </code></pre>
  
  <p>I encountered an error kind of like this before with a previous plugin before, but missing resource was from the <strong>appcompat-v7</strong> library and was because I had a mismatch with the appcompat-v7 library version and my <strong>compileSdkVersion</strong>. All I had to do was update my appcompat-v7 and compileSdkVersion to the latest versions and all was set.</p>
  
  <p>But this instance seems to be from a third party library and I'm using the latest version of the library. I don't know how to go about fixing this</p>
