Failed to match codes between repo and fixes.yml.

In my action, the running log shows that "No warnings found in files changed in this pull request". This error also happened in #17 .

@kenji-miyake All file paths in your fixes.yaml begin with /__w/... (probably because clang-tidy is running self-hosted) while this action expects the GitHub directory layout (/home/runner/...), so it can't normalize paths and is not able to find all these files from your PR.

Thanks @oleg-derevenetz points out that there is another file system in a custom actions container.

I wonder is there a proper way to avoid modifications on fixes.yaml? Maybe GitHub environment variable GITHUB_WORKSPACE helps, creating a symlink from from /home/runner/... to /__w/... .

[caic99]

This might because the job is run in a container, and the working directory defaults to /__w/ in it. ref

[caic99]

Actions that run in Docker containers have static directories under the /github path. ref

If you have steps that use both script and container actions, the container actions will run as sibling containers on the same network with the same volume mounts. ref

What confuses me is the file system and mapping strategy among these two containers and the host system. After all, the fixes.yml is read normally.

@caic99 Yeah, just like I suspected, it seems that the GITHUB_WORKSPACE variable points to the different directory inside a custom action container:

A tested workaround goes here.
