Expected Behavior

When I specify all the output formats with my specified filenames, they should be created.

Current Behavior

The action fails with:

Run sudo chown -R $USER:$USER .tmp
sudo chown -R $USER:$USER .tmp
shell: /usr/bin/bash --noprofile --norc -e -o pipefail {0}
env:
run_number: ${GITHUB_RUN_NUMBER}
chown: cannot access '.tmp': No such file or directory
Error: Process completed with exit code 1.

Possible Solution

The step "Post: Change folder own group" which does run 'sudo chown -R $USER:$USER .tmp' should only occur if .tmp exists. Or if it does occur, ignore the error.

Steps to Reproduce

Link to live example build https://github.com/ikenna/acme-pet-supplies/runs/7460315228?check_suite_focus=true

1. Run the action, specifying all the available output formats in custom filenames. E.g

  - name: "Run breaking change check (with OpenAPITools/openapi-diff)"
    id: diff_state
    uses: swimmwatch/[email protected]
    with:
      old-spec: base/reference/product-catalog-api.oas.yaml
      new-spec: head/reference/product-catalog-api.oas.yaml
      json: "diff.json"
      markdown: "diff.md"
      text: "diff.txt"

Context (Environment)

1. Failing build with all the formats specified in a non .tmp path : https://github.com/ikenna/acme-pet-supplies/runs/7460315228?check_suite_focus=true

2. Passing build with only three formats specified in a non .tmp path : https://github.com/ikenna/acme-pet-supplies/runs/7460555288?check_suite_focus=true

Detailed Description

I can't successfully run the action if I specify custom names for all the output formats. But I can if I specify a subset.

Possible Implementation

Ignore the error if .tmp does not exist.

run: sudo chown -R $USER:$USER .tmp 2>/dev/null
