title: Gerrit - Reload Plugins to incorporate changes
body: <p>I am developing some plugins for Gerrit 2.9 and usually copy the jar file into the Gerrit site's plugin folder. </p>
  
  <p>However, I notice that it usually takes a while for Gerrit to pick up the changes made in the plugin jar file. One thing that automatically forces Gerrit to reload the plugins is to restart the server itself. </p>
  
  <p>Next, I tried <code>ssh -p 29418 localhost gerrit plugin reload &lt;plugin-name&gt;</code>, however I get an error saying that <strong>"Fatal: Remote plugin administration is disabled"</strong>. </p>
  
  <p>To solve the above message, I was able to find <a href="https://groups.google.com/forum/#!topic/repo-discuss/3VRnSaHSum8" rel="noreferrer">this post</a> where the suggestion is to   <strong>add missing configuration option: "plugins.allowRemoteAdmin = true"</strong>. However I am not sure where to add this configuration option. </p>
  
  <p>So any ideas on how to do a force reload of Plugins without having to restart the Gerrit server itself ? </p>
