               Bringing GitPubSub to the Apache Jenkins build server
           </h1>
               <p>Posted on: 2017-03-26 01:07:08+00:00</p>
               <p>
 When it comes to <a href="#Jenkins">[Jenkins</a>], it has long been known that [polling must die].
 </p>
 <p>While we could go and create post commit hooks in all the ASF hosted Git repositories, that is something that realistically is just creating an added maintenance burden.
 <p>In any case, we have [GitPubSub]. </p></p>
 <p>The question then becomes, how do we integrate [GitPubSub] with [Jenkins]?
 <p>Thankfully, ASF committer stephenc is also an active committer to the [Jenkins] project and created a [plugin] that connects to [GitPubSub] parses the events and passes them through to the Jenkins [SCM API].</p>
 </p>
 <p>
 What does this mean?
 </p>
 <p>* You can turn your Git polling down - way way down - to something like once per day.
 This should significantly reduce the load on both the ASF git servers and builds.apache.org<br/>* Your builds will be triggered in seconds rather than having to wait for the next polling run.<br/>* You can try out using Multi-branch projects much like the [Maven] project has been doing for [Maven core] and [Maven Surefire]
 </p>
 <p>
 If the reaction to this change proves positive, the next step will be to integrate SvnPubSub with Jenkins and bring the benefits to the Subversion based projects too
