Resolution

If you have installed a recent version of Git for Windows, during the installation there is an option to enable/disabled the Git Credential Manager for Windows.

git for windows option

This option is enabled by default and set the git property credential.helper at a system level. This forces the git client to use the Git Credentials Manager for Windows instead of the local configuration provided by Jenkins. Consequently it makes your build either hang (if running the node as an System Account) or fail (if running the node as a local User).

To workaround that behavior there are 3 different solutions:

  1. Unset the system property via a terminal

    Run as administrator:

    git config --system --unset credential.helper

    If configuration exists for the account used to run the Jenkins Agent process, you may need to remove the system property for it. By editing the $USER_HOME/.gitconfig file or running the following command:

    git config --global --unset credential.helper

    You may also need to edit the global config file by doing git config --edit --global and remove the line:

     helper = manager

    Then potentially add the line:

     [core]
    askpass =
    It is best to reboot the Jenkins Agent machine to ensure no orphan "Windows Git Credential Manager" processes previously started by Jenkins are still running.

  2. Uninstall/Re-install git-for-window and ensure to disable the option "Enable Git Credential Manager" during the installation.

  3. Use the portable version of git-for-windows (no installer)
