+# Vendored from gitea.com/actions/gitea-upload-artifact commit 81f940d004763f986ba3582c007fd842dd5cb0d7.
+name: 'Upload a Build Artifact'
+description: 'Upload a build artifact that can be used by subsequent workflow steps'
+author: 'GitHub'
+inputs:
+  name:
+    description: 'Artifact name'
+    default: 'artifact'
+  path:
+    description: 'A file, directory or wildcard pattern that describes what to upload'
+    required: true
+  if-no-files-found:
+    description: >
+      The desired behavior if no files are found using the provided path.
+
+      Available Options:
+        warn: Output a warning but do not fail the action
+        error: Fail the action with an error message
+        ignore: Do not output any warnings or errors, the action does not fail
+    default: 'warn'
+  retention-days:
+    description: >
+      Duration after which artifact will expire in days. 0 means using default retention.
+
+      Minimum 1 day.
+      Maximum 90 days unless changed from the repository settings page.
+  compression-level:
+    description: >
+      The level of compression for Zlib to be applied to the artifact archive.
+      The value can range from 0 to 9:
+      - 0: No compression
+      - 1: Best speed
+      - 6: Default compression (same as GNU Gzip)
+      - 9: Best compression
+      Higher levels will result in better compression, but will take longer to complete.
+      For large files that are not easily compressed, a value of 0 is recommended for significantly faster uploads.
+    default: '6'
+  overwrite:
+    description: >
+      If true, an artifact with a matching name will be deleted before a new one is uploaded.
+      If false, the action will fail if an artifact for the given name already exists.
+      Does not fail if the artifact does not exist.
+    default: 'false'
+
+outputs:
+  artifact-id:
+    description: >
+      A unique identifier for the artifact that was just uploaded. Empty if the artifact upload failed.
+
+      This ID can be used as input to other APIs to download, delete or get more information about an artifact: https://docs.github.com/en/rest/actions/artifacts
+  artifact-url:
+    description: >
+      A download URL for the artifact that was just uploaded. Empty if the artifact upload failed.
+
+      This download URL only works for requests Authenticated with GitHub. Anonymous downloads will be prompted to first login. 
+      If an anonymous download URL is needed than a short time restricted URL can be generated using the download artifact API: https://docs.github.com/en/rest/actions/artifacts#download-an-artifact    
+
+      This URL will be valid for as long as the artifact exists and the workflow run and repository exists. Once an artifact has expired this URL will no longer work.
+      Common uses cases for such a download URL can be adding download links to artifacts in descriptions or comments on pull requests or issues.
+runs:
+  using: 'node20'
+  main: 'dist/index.js'
