I have provided branch specifiers as shown in the attached image. If I remove the branch specifier with $BRANCH in it, job works perfectly(gets triggered) as anyone commits to develop or feature branches.

Now I also want that same job should also be able to build the project on any specific branch of choice. So I added a branch specifier and put $BRANCH in it. I have defined BRANCH as a string parameter and the user can give branch value as input when triggering the job manually.

But in this scenario even if the user gives a "bugfix112" job is still building develop branch. Or if earlier poll action had built the job on feature branch than even after providing user-input, the job will still build feature branch.

It seems like manual input has no effect. How can I configure a Jenkins job that can be triggered on poll SCM and also with user input for the branch parameter?

I also tried giving /$BRANCH,/${BRANCH} but no success.
