The jenkins plugin was initially written to update the status update on

the review request once the build completed (either successfully or

not). This change enhances the notification in several ways:

We now post a change to the status update when initially applying the

  patch. This will change the status from "starting build" (assigned by

  the integration) to "build running".
Add a link to the in-progress build.
Fix the post-build notification to properly use the error state

  instead of failure, when the build failed because of some non-code

  related issue.

Ran plugin unit tests.
Built and loaded the plugin into my Jenkins instance.
Posted a change to a review request. Saw that the status soon changed

  to "build running" with a correct link to the build. Saw that the

  build finished successfully.
