title: Specify chromedriver path to selenium-standalone
body: <p>I am trying to start the selenium-standalone server (<a href="https://www.npmjs.com/package/selenium-standalone" rel="noreferrer">https://www.npmjs.com/package/selenium-standalone</a>) and it is throwing an error:</p>
  
  <pre><code>14:19:09 /usr/local/lib/node_modules/selenium-standalone/bin/selenium-standalone:54
  14:19:09         throw err;
  14:19:09               ^
  14:19:09 Error: Missing /usr/local/lib/node_modules/selenium-standalone/.selenium/chromedriver/2.18-x64-chromedriver

  14:19:09 Build step 'Execute shell' marked build as failure
  </code></pre>
  
  <p>The selenium server is looking for the chromedriver at path </p>
  
  <blockquote>
    <p>/usr/local/lib/node_modules/selenium-standalone/.selenium/chromedriver/2.18-x64-chromedriver</p>
  </blockquote>
  
  <p>by default.</p>
  
  <p>Is it possible to specify the chromedriver location at the command line while running the server? Something like:</p>
  
  <pre><code>selenium-standalone -Dwebdriver.chrome.driver=&lt;path_to_chromedriver&gt; start
  </code></pre>
