The Git polling is distilled into a more developer-useful format that shows commit comments as well
as hyperlinking usernames and changed files to more detailed views of each.

Installing the Gerrit Build Trigger adds a Gerrit event option that can be more efficient and precise than
simply polling the repository.

Gerrit^6 is an open source web application that facilitates code reviews^7 for project source hosted on a
Git version control system. It reads a traditional Git repository, and provides a side-by-side comparison
of changes. As the code is reviewed, Gerrit provides a location to comment and move the patch to an
open, merged, or abandoned status.
The Gerrit Trigger^8 is a Jenkins plugin that can trigger a Jenkins build of the code when any user-
specified activity happens in a user-specified project in the Git repository (see Figure 5.18, “Gerrit
Trigger”). It is a alternative to the more typically-used Build periodically or Poll SCM.
