Unable to trigger build using 'Poll SCM' and Git notifyCommit option

[Garbageyard]

We use Jenkins (1.614) and have Git as version control tool. The Git plugin version is 2.3.5. I am trying to trigger build only after every check-in since continuously polling is too expensive. I tried the following method described in various links but it’s not working:

1. Enabled ‘Poll SCM’ and assigned a dummy value. I also tried without assigning any value.

2. Added following line in post-receive hook:

curl http://jenkins_url:9099/jenkins/git/notifyCommit?url=ssh://gitolite@git_server/TestRepo

3. Now if I commit some changes, I get the following message during push:

$ git push origin release-test

remote: No Git consumers using SCM API plugin for: ssh://gitolite@git_server/TestRepo

4. When I see the Git Polling Log, I notice the following:

Started on Jun 10, 2015 6:42:04 PM

No existing build. Scheduling a new one.

Done. Took 0 ms

Changes found

5. I do see the build # getting incremented after every such poll for few seconds but 'Build History' remains empty as shown in attachment. No steps that are part of the build are executed.

Any inputs why the build is not getting triggered as expected?
