In Gitlab CI, how do you trigger a build only if changes happen on particular set of files?
Is there a way to either include or exclude certain files from triggering a build? For eg: updating README.md, .gitignore files should not cause a build to trigger.

If you are using a declarative syntax of Jenkinsfile to describe your building pipeline, you can use changeset condition to limit stage execution only to the case when specific files are changed. This is now a standard feature of Jenkins and does not require any additional configruation/software.
GitLab CI/CD Trigger is the most common and convenient technique for triggering CI/CD. GitLab CI/CD pipelines, by default, are executed automatically when new commits are pushed to a repository and do not require any intervention once created.
Run jobs for scheduled pipelines To configure a job to be executed only when the pipeline has been scheduled, use the rules keyword.
UPDATE 2
Only/except seem to be an unstable feature. The doc recommends using rules:changes instead:
job: script: - build # replace with your build command rules: - changes: - /*.{java, py} # ... or whatever your file extension is - dockerfiles/**/* # all files under folder 'dockerfiles' UPDATE 1:
Like Gajus mentioned in the comments, it is now possible!

Original post:
No, it is not possible – not now!
I think this is the issue you are looking for: https://gitlab.com/gitlab-org/gitlab-ce/issues/19232 – It is a very high rated issue (over 100 thumps-up).
The milestone has changed to Next 3-6 months, 4 months ago. (https://gitlab.com/gitlab-org/gitlab-ce/issues/19232#note_31943850) I hope we will see this function soon.

Update: This is now possible as of 11.4, see https://docs.gitlab.com/ee/ci/yaml/#onlychangesexceptchanges
Original post:
There's not currently any way to trigger a build in GitLab CI conditionally based on which files have been edited.
I've thought about this feature myself before, and I think it could be very useful for a number of different use cases.
The closest issue I could find for this is https://gitlab.com/gitlab-org/gitlab-ce/issues/23010
Anyway, to answer your question:
You can't really do this right now – even manually – since there's no way to determine if a merge request has changed a file or not since CI has no concept of a merge request.
Pipelines "understanding" what Merge Requests are should be added sometime soon.

Accidentally found your question. I thinks it's a little bit late :), but that feature available since version 11.4
see docs
