Poll SCM using Jenkins not working

Balu Pillai (1324) | asked Jun 20 '19, 11:47 a.m.

 Hi dear all, 

I have been trying to setup a job that polls the SCM (Jazz) and automatically run when a change is detected in the repository. I have enabled the "Poll SCM" option in Jenkins (@ every 5 mins) and I can see that Jenkins is trying to poll (from the logs), but it comes back saying no change detected which is not true.

I am trying to figure out why? My workspace is configured to follow the required streams I am interested in and Jenkins is configured with the Team Concert Plug in. Am I missing something? Please advise.

Is your Jenkins job configured to use a Build Workspace? If so can you confirm if the Build Workspace is used just in this particular Jenkins job and not in any other jobs/ Build Definition?

Hi Sridevi, 

Thanks for your suggestion. I have managed to get it working, it was a configuration error - my bad. Jenkins was running out of heap space at the server (all of a sudden), so RTC checkout/polling was not working as I expected it to. I understand this is not directly related to the topic, but for anyone who comes across this problem: 

- I used Java melody plug in to profile and have increased the memory now in the Jenkins.xml file from a default value of 256MB to something higher.

 See and see and type Jenkins into the search field. Should that not be enough, consider to provide information about how you configured the Jenkins Job.
