Description:

There seems to be a problem related to the core.symlinks config option. Usually, if core.symlinks is not set (the default), Git will probe the target file system for symlinks support when cloning (see [1]). As Windows does not support symlinks in the POSIX sense, Git for Windows internally uses core.symlinks=false if that option is otherwise unset. However, relying on this results in this error for me (see [2]):

{code}
Directly using Git from the command line on the server works fine to clone the repository, I do not get any errors about being unable to create symlinks then.
The error
in Jenkins
disappears when I explicitly do "git config --system core.symlinks false" on the build server (see [3]).
