Jenkins version - 1.549 Git plugin ver - 2.0.1

Answer 1

Finally, the native git for windows has an option for long paths:

The msysgit development team has implemented what appears to be a solution in msysgit 1.9.0. It appears that the solution needs to be specifically enabled, but it may allow you to resolve this problem by installing msystgit 1.9.0 and running

git config --global core.longpaths true

Refer to https://github.com/msysgit/git/commit/c5f98452e98dca292c615000df7973ead63cf29b for more details on the option. You should probably only enable that option if you encounter the problem, since the msysgit people warn that there may be compatibility issues with other tools when longpaths are enabled in core git.

Answer 2

We had the same issue. After some research it seems that the Jenkins git plugin cannot cope with too long paths (> 259 chars) under Windows environments. To be more precise - the git plugin uses git via command line in the latest version and this cannot cope with too long paths. Formerly it used JGit implementation that doesn't have this issue. You can still switch back to this implementation with the Jenkins command line argument:

"-Dorg.jenkinsci.plugins.gitclient.Git.useCLI=false" (same for slaves)

or just choose JGit as implementation in the Jenkins configuration dialogue.

With this everything runs fine. But don't forget that JGit is no fully featured native git!
