title: How to debug or resolve "Error: The current project can not be run" for Run Configuration for Android Instrumented Tests?
body: <p>I have a <a href="https://github.com/janpio/separate_test_module/tree/old-gradle-extracted" rel="nofollow noreferrer">project</a> (created via this <a href="https://stackoverflow.com/a/46441463/252627">StackOverflow question</a>) that has a <strong>module</strong> with an <strong>Android Instrumented Test</strong>. It can be run via a normal Configuration where the module is selected. </p>
  
  <p>This works for Android Gradle plugin &lt;=2.2.3 and >=3.0.0-beta1. But as soon as I change the project to Android Gradle project 2.3.x (2.3.0 -> 2.3.3) I get this error message for my run configuration:</p>

  <p>I found no way to get more information or debug this error message in any way. There is nothing highlighted in this window or anywhere else.</p>
  
  <p>Any idea what could be causing this?
  How can I debug this error message to find out what is wrong with my project?</p>
