  <p>but I can not find gradle home.</p>
  
  <pre><code>echo $GRADLE_HOME
  [empty result]
  </code></pre>
  
  <p>the first step to determine home directory is detect location of <code>gradle</code> instruction:</p>
  
  <pre><code>which gradle
  /usr/local/bin/gradle
  </code></pre>
  
  <p>there is incomprehensible bash file.</p>

  <p>Any ideas how to detect gradle home directory via terminal?</p>
