I have an action whose problem matcher seems to only fail when run self-hosted. The file is getting dropped due to not being under the workspace root:
- File "./src/demo.v", line 5, characters 7-13: ##[debug]Dropping file value '/home/ubuntu/coq-ci/actions-runner/_work/coq-github-ci-test/coq-github-ci-test/src/demo.v'. Path is not under the workflow repo.
I’m not exactly sure how to debug this since I don’t know what the workflow repo is, but I was surprised to find that while RUNNER_WORKSPACE is
/home/ubuntu/coq-ci/actions-runner/_work/coq-github-ci-test like I’d expect, GITHUB_WORKSPACE is
/github/workspace when my action runs (even though it was the same as RUNNER_WORKSPACE during actions/checkout@v2).
The full logs are at https://github.com/tchajed/coq-github-ci-test/runs/714375293.
