title: Jenkins ver. 2.32.3 - can't install selenium plugin
body: <p>I try to use jenkins to test my PHP facebook webdriver selenium project.
  Jenkins fails to install the selenium plugin. It just loads forever on the installation process:</p>

  <p>In the plugin description I found out that I have to run jenkins on Java 8.</p>
  
  <blockquote>
    <p>(!) This plugin requires Jenkins to run under Java 8 as of version
    3.1.0 (!)</p>
  </blockquote>
  
  <p>So I have installed the latest version from the repository...</p>
  
  <pre><code>java version "1.8.0_121"
  Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
  Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)
  </code></pre>
  
  <p>...and tried it again. But still the installation process does not make any progress. It stays for hours.</p>
  
  <p>What am I doing wrong?</p>
