|
| 8 | +Arguments: |
| 9 | + owner : GitHub user or organization of the target repo |
| 10 | + repo : Target repo name |
| 11 | + branch : Branch name (e.g. main) |
| 12 | + target-path : Full path (including folders + filename) in the target repo where to upload |
| 13 | + artifact-file : Local file path to upload |
| 14 | + commit-message : Commit message for creating/updating the file |
| 15 | + github-token : GitHub token (PAT or equivalent) with write access to the target repo |
| 16 | +
|
| 17 | +This will perform a GitHub API PUT to /repos/{owner}/{repo}/contents/{target-path}. |
| 18 | +If a file already exists at that path, it will auto-detect the SHA and update; otherwise it will create a new one. |
