The repository in the workspace on the agent running that build is probably damaged. Wipe the workspace on the agent and run the job again.
If wiping the workspace and running the job again does not resolve it, you may also be encountering a timeout while cloning the repository. Increase the timeout for the repository clone from its default of 10 minutes to something large enough that it will allow you to clone the repository. The amount of output you're showing hints that the repository is large or the network connection between the agent and the upstream cloned repository is slow. In either of those cases, you probably want to reduce the clone time and the disc space use by applying one or more of the techniques described in "Git in the Large <https://youtu.be/jBGFjFc6Jf8?t=6434>". Those techniques include (1) reference repositories on the agent, (2) narrow refspecs, (3) shallow clones, and (4) sparse checkouts. If this is a Pipeline repository and the failure is during the initial clone of the repository, then you may also need to use lightweight checkout to only checkout the Jenkinsfile rather than the entire repository. Alternately for Pipelines, if your git provider is GitHub, Bitbucket, or Gitea, you can significantly improve performance by using those branch source plugins to manage the Pipeline instead of relying on low-level command line git calls. Reference repositories are usually the most effective technique to reduce data transfer time and disc space use for large git repositories. Allan Burdajewicz of CloudBees wrote a great article on reference repositories at https://support.cloudbees.com/hc/en-us/articles/115001728812-Using-a-Git-reference-repository .
