I setup a job to build feature branches and skip the master branch. I do this by specifying "*/master" as the branch to build and then inverse as the choosing strategy. I have the job setup to poll SCM every 15 minutes (I don't have access to change the hooks).

When I push changes to a branch other than master, the job does as expected and builds the branch. However when I push changes to master, the job runs and builds the last branch it built. I left this overnight and have a build every 15 minutes of the same commit.
