title: how to correct an incorrectly imported project in Intellij. Getting error - Not a valid project ID
body: <p>I cloned my repo and using the existing <code>build.sbt</code>, I imported the project in <code>Intellij</code> (I don't remember the setting I used when doing so). I notice that <code>Intellij</code> have the project a name of its own - <code>web_3075</code> while the name of my project is <code>TestProject</code> (<code>name := "TestProject"</code>). Now when I try to compile the project, I get the error <code>Not a valid project ID: web_3075</code>. How could I solve the issue?</p>
  
  <p>Could I safely delete <code>.idea</code> file and import the project again?</p>
