Check Artifact v4 Existence

A composite Github Action inspired by the very awesome xSAVIKx/artifact-exists-action

Checks if an artifact with a given name, uploaded with actions/upload-artifact@v4, exists. Only works with the actions/upload-artifact v4 and later, not versions v1-v3.

Inputs

• name (required) - Name of the artifact to check

Outputs

• exists - Whether the artifact exists and could be downloaded. true if it the artifact was downloaded, false it couldn't be downloaded. It could also be null if something in the composite workflow failed and it never couldn't got to the end, if the download-artifact call was skipped or something else strange happened.

Example usage

- uses: softwareforgood/check-artifact-v4-existence@v0
  with:
    name: "example-artifact"
