I have a job where the git refspec and branch are set to +refs/heads/${branch}:refs/remotes/origin/${branch} and the branch is set to ${branch}.
With that configuration, the SCM polling keeps triggering new builds from the same change.
If I replace the variables with their values, the SCM polling works correctly.

[JENKINS-22009] Git Polling Keeps Detecting Changes When Variables in refspec
Daniele Vigano
added a comment - I can confirm this bug. With Jenkins 1.572, git client plugin 1.9.2 and git plugin 2.2.2 the polling module does not resolve our "$branch" variable, set in the parametrized build configuration:

added a comment - I've hit this bug too, when using parameters in the Branch Specifier field. Git plugin 2.2.2, Git client plugin 1.9.2, Jenkins 1.554.3 LTS.
You can work around this bug by disabling remote polling for the affected jobs. (I think this is true for most of the git trigger bugs listed here [1].) I have a Jenkins script (for Script Console or Scriptler) which disables remote polling for all jobs [2].

added a comment - pull requests were merged in master and 2.2.x 
I agree with this bug .... older versions of the Git plugin used to properly resolve variables in the "branches to build" field in both parameterized builds and polling. Now, it seems that polling does not resolve variables when issuing the ls-remote command. Can someone look into this – it seems like a trivial thing to fix.
Thanks.
