title: Jenkins Not detecting changes on parent repo
body: <p>I have a question . I am using Jenkins 1.6 as a CI tool and mercurial version 3.7.3 . In the build process, I have two WAR files DEVICE and REST . My issue was, Jenkins was detecting changes only when there is a change in device and war files. I mean only on the child repo's and It is not detecting If I make any changes on the parent Repo . Is there any flaw in my Build process.. ? Please find the attached image .
