title: Gradle home can not be found
body: <p>My Android Studio project cannot be built because I get the error:</p>
  
  <pre><code>Error running build: Gradle home can not be found
  </code></pre>
  
  <p>Gradle home cannot be found now but it worked before in this project, so I assume it is not about the <code>GRADLE_USER_HOME</code> variable. I can build any other project, old and newly created.</p>
  
  <p>It stoped working after I created new activity and deleted it manually. What can be reason for this</p>
  
  <p>EDIT:
  I tried to build app today and everything worked, so there is no problem anymore. But still I have no idea what that was.</p>
