Atlassian Bamboo: don't trigger build if changes were made to a specific file

Question

I have a plan in Bamboo that starts whenever changes are made to the attached repositories (via polling).

Now, on each build, if successful, a CHANGELOG file is updated in the repo, which in turn, triggers another build. How can I omit certain files from Bamboo's polling, so that a build isn't started if changes are found for those files? Because otherwise, I enter in infinite loop, with a change to CHANGELOG triggering another build which in turn updated CHANGELOG and so on.

If this is not possible, what other viable solutions are there? Is it possible to attach a shell script somewhere before the build starts to check whether it's desired to start a new build?

Answer 1

It turned out that this was simpler than I've thought. In Plan Configuration, in the Repositories tab, on each repository, under Advanced, there is an Include / exclude files input where you can Customise what files Bamboo uses to detect changes. By adding a regular expression there, I got everything solved and working as expected.
