How to only trigger on changes to specific file(s)

Drone Support

Drone has several conditions to trigger off. Is there one that will trigger off changes to specific files or dirs ? Main example would be to NOT trigger when README.md is changed, only when the main repo files change.

Using gitlab only: changes: type syntax maybe ?

Very annoying to have a pipeline run when a 2-word change to README.md is pushed.

Hi @Halfwalker!
All Drone triggers are content-independent. As a workaround you may use exit 78 command to exit your pipeline stages before compilation steps. Here is an example:

---
kind: pipeline
type: docker
name: default

steps:
- name: trigger
  image: plugins/git
  commands:
  - test $DRONE_BUILD_EVENT = pull_request
    && DIFF_STRING=origin/${DRONE_COMMIT_BRANCH:-master}
    || DIFF_STRING=${DRONE_COMMIT_SHA}~
  - git --no-pager diff --name-only $DIFF_STRING
    | grep -q -e ^[.]drone[.] -e ^Makefile$ -e [.]c$
    || exit 78

- name: build
  image: gcc
  commands:
  - make

- name: test
  image: gcc
  commands:
  - ./test

...

If you want to limit pipeline or pipeline step execution based on files changed, you can install an extension for this. See https://github.com/meltwater/drone-convert-pathschanged

Yeah, I saw that, thanks. Unfortunately it does’t support Gitea (yet).
