File already exists error

[ewpratten]

Behaviour

When deploying a directory with this action, I am getting the error:

##[error]EEXIST: file already exists, symlink '/home/runner/.cache/bazel/_bazel_runner/17d8e9b30b69e9aeac686c3673f39b5a/execroot/highschool_notes/bazel-out/k8-fastbuild/bin' -> '/tmp/github-pages-vbZ3SF'

For clarification, I am using the bazel buildsystem and pandoc to generate some HTML outputs from LaTeX files. After running, Bazel creates the following symlinks in the workspace directory:

bazel-bin -> /home/runner/.cache/bazel/_bazel_runner/17d8e9b30b69e9aeac686c3673f39b5a/execroot/highschool_notes/bazel-bin
bazel-highschool_notes -> /home/runner/.cache/bazel/_bazel_runner/17d8e9b30b69e9aeac686c3673f39b5a/execroot/highschool_notes/bazel-highschool_notes
bazel-out -> /home/runner/.cache/bazel/_bazel_runner/17d8e9b30b69e9aeac686c3673f39b5a/execroot/highschool_notes/bazel-out
bazel-testlogs -> /home/runner/.cache/bazel/_bazel_runner/17d8e9b30b69e9aeac686c3673f39b5a/execroot/highschool_notes/bazel-testlogs

I would expect that this just deploys as per usual (I have no problems in many other projects)

If needed, I can invite you to the private repo where this build is being run

[ewpratten]

I added a shell script that manually copies files from inside the symlink to a local folder, and fixed the issue. I'm guessing that the built-in copy function isn't set up to handle symlinks

[crazy-max]

Hi @ewpratten, yes indeed, symlinks are not handled properly. I will push a fix. Thanks for your feedback.

[ewpratten]

Alright, thank you. I'll close this issue

[crazy-max]

@ewpratten Should be fixed now
