CI/CD release custom ZIP-file name and custom top-level directory?

We want to create Moodle plugins which need custom zip-file names and a custom top-level directory.

How can we download CI/CD ZIP-files from Gitlab via cURL with correct filenames?

• What version are you on?

  • GitLab Community Edition v16.3.0

• Are you using self-managed or GitLab.com?

  • Self-managed

• What troubleshooting steps have you already taken?

  • Release → wrong ZIP file name and wrong top-level directory.
  • Artifacts → wget and cURL cannot resolve filename from headers.
  • zip-command in .gitlab-ci.yml + Generic Package Repository → wget and cURL cannot resolve filename from headers.

• Can you link to any docs or other resources so we know where you have been?
  Predefined variables reference | GitLab
  `.gitlab-ci.yml` keyword reference | GitLab
  Releases | GitLab
  Job artifacts | GitLab
  GitLab Generic Packages Repository | GitLab

If the GitLab provided packaging is not working for you, you need to package the plugin into ZIP archive yourself and upload that to GitLab Generic Packages Repository in the CI/CD pipeline.

That’s what I wrote in the troubleshooting section.
wget and cURL cannot resolve the filename from the headers of the links of the Generic Packages Repository.

I am not sure what headers are you referring to. Could you please elaborate with an example what you are trying to do?

Artefacts have a long Download-Link which ends with /download. If the link is downloaded with cURL or wget the filename is download. Adding options to cURL or wget to extract the filename from the HTTP-header do not help. The filename is still download.

I am usually using GitLab API endpoint to download packages as it is documented in GitLab Generic Packages Repository | GitLab and this always worked for me

curl -OJ https://gitlab.com/api/v4/projects/<projectid>/packages/generic/<package_name>/<package_version>/file.zip

So in your case probably something like curl -OJ https://gitlab.com/api/v4/projects/<project_id>/packages/generic/moodle-<plugin-type>_<plugin-name>/<tag YYYYMMDDnn>/<plugin-type>_<plugin-name>_moodle<Moodle_MajorMinor_version>_<tag YYYYMMDDnn>.zip
