Github workflow excluding paths does not work

I cannot get the Github workflow feature to exclude paths to work properly and could not find a similar problem on stack overflow. The most similar case is Github workflow does not trigger on push for path based filtering but it has not helped me.

I have the workflow for PRs below:

name: Build For PRs

on:
  pull_request:
    types: [opened, synchronize, ready_for_review]
    paths:
      - 'src/**'
      - '!src/abc/**'
      - '!src/def/**'
      - '!src/ghi/**'
      - '!src/docker-compose*.yml'
      - '!**.md'

I want it to run on PR's when any file under "src" changes, except when one of the negative filters is a match.

Even changing a .md file triggers this WF. How can I achieve the logic above?

The problem is that excluding paths doesn't work as you want by design.

When all the path names match patterns in paths-ignore, the workflow will not run, but if you have at least one file that doesn't fall under negations - workflow will still run.

So there is no way to stop workflow by this feature the way you want to do - to stop workflow when at least 1 file belong to excluded list.

I would recommend filtering changed files and then stopping workflow if you find any files matching your criteria and use https://github.com/tj-actions/changed-files/ instead. With that action you will be able to check if any files are fitting your criteria and then you just stop the workflow. Unfortunately it will start full workflow, create a runner and execute workflow itself.
