GitHub access using access token and Basic Authentication no longer working

[Chris Jansen]

Hi,

I have been using a GitHub personal access token and basic authentication to pull from private GitHub repos from Jenkins. I use the GitHub Plugin, and then for each project, the GitHub Project and Git Repository URL settings are the same, with a format of: https://<user>:<access_token>@github.com/<account>/<repo>/.

This has been working fine for months, until this past Wednesday. Now whenever I build I get an 'Invalid username or password' error (see below).

I recreated the GitHub access token, which didn't fix the problem. I'm think the issue is on the Jenkins side, since I can use the same URL on the command-line to clone the repo, and it works fine.

I upgraded Jenkins to 1.558, but then reverted back to 1.555, thinking the upgrade could have caused the problem. I'm still stuck without being able to pull from GitHub though.
