title: Gradle NOT finding my subdirectory to build
body: <p>I have an application with subdirectory(projects) inside this project like this</p>
  
  <ul>
  <li>My Application
  
  <ul>
  <li>Project a</li>
  <li>Project b</li>
  <li>Project c </li>
  </ul></li>
  </ul>
  
  <p>etc...</p>
  
  <p>I'm trying to build Project b from the root folder (My Application) using this command:</p>
  
  <pre><code>gradle :Project b:build
  </code></pre>
  
  <p>But I got this error message:</p>
  
  <blockquote>
  <pre><code>* What went wrong:
  Project 'Project b' not found in root project 'MyApplication'.
  
  * Try:
  Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output.
  </code></pre>
  </blockquote>
  
  <p>But if from <strong>My Application</strong> I do this using command line: </p>
  
  <pre><code>cd Project b 
  </code></pre>
  
  <p>and then run the build</p>
  
  <pre><code>gradle build
  </code></pre>
  
  <p>It builds successfully. What am I doing wrong?</p>
