Git credential issue when working with Jenkins End-to-End Multibranch Pipeline Project Creation

Question

Image of Error - Git credential validation failed with an unexpected error. Please try again

When working on the initial End-to-End Multibranch Pipeline Project Creation project for Jenkins, it is asking for credentials when connecting to the local /home/user_name/GitHub/building-a-multibranch-pipeline-project to access the local git files. I have tried an array of different approaches form providing my system credentials to my git credentials but nothing seems to work.

The workflow for this project is as follows:

• install Jenkins
• run docker instance code below
• fork and clone git repo locally into /home/user_name/GitHub
• create a pipeline with Git <- this is where the Git error occurs
• Tutorial link: https://jenkins.io/doc/tutorials/build-a-multibranch-pipeline-project/

I realize this is probably a very simple problem, but I greatly appreciate any help.

Answer 1

Check if using the file protocol as an URL would be enough to convince Jenkins and its Credential plugin that is does not need username/password:

file:///home/GitHub/building-a-multibranch-project

The idea is: for local file-based access, there is no authentication with Git.
