I'm attempting to download build artifacts from Jenkins via curl in a Bash script. However, I use GitHub for authentication, and even using the API key belonging to an Administrator user, I only get 403 errors and cannot successfully download.
My curl command is as follows:
curl -u me:myapitoken -k 'https://jenkins.example.com/job/my-project/lastSuccessfulBuild/artifact/output/artifact_name'`
The header output indicates that Jenkins considers me logged in as an Administrator, yet, I get the 403 error and am unable to download the artifact.

The link works fine in the browser whilst logged into GitHub and Jenkins.
Does anyone have any idea to authenticate via curl when using GitHub as a primary authentication provider?
So apparently this was due to a bug in the GitHub Authentication plugin. Installing the latest updates has fixed the issue and allowed me to authenticate using the API key.
