Jenkins "Path Too Long" error

[mlapaglia]

When running gitversion command on a scripted pipeline inside Jenkins I get

When I navigate manually to the folder and execute gitversion it prints out the version correctly. I'm on Windows Server 2019 and have long filepaths enabled.
Why does the command work when I run it outside of the build agent? Is there a way to make it behave the same while running in Jenkins?

It is because libgit2sharp cannot handle longpaths on windows there are a couple of issues raised on the libgit2sharp project repo on github. I have the same issue on Teamcity... been driving me mad trying to fix it. Basically on windows any repos that have node or any other long filenames in any projects you are stuffed as gitversion for windows is broken. However what I have found is that the /nofetch flag is not honored in so much as This step "Normalizing git directory for branch" is concerned it goes to the remote repo anyway which uses LibGit2Sharp to interact with the remote repo. In teamcity I have set that the agent does a full pull to the working folder on the agent. I also set the /nofetch flag. i.e. "/nofetch true"
