Adam Brousseau created an issue   Jenkins / JENKINS-54612 Reference repo not used for Git clones on Windows SSH agents Issue Type: Bug Assignee: Mark Waite Components: git-plugin Created: 2018-11-13 20:15 Environment: Jenkins 2.138.2 Git Plugin 3.9.1 Windows 2012r2 Cygwin Git 2.17.0 Labels: windows git Priority: Minor Reporter: Adam Brousseau We use a reference repo on all our agents to speed up our clones. This seems to work on all agents we have except for our Windows nodes. I first noticed that the fetch times were slower on the Windows nodes. I then confirmed by checking the size of the .git folder on each machine after the clone. All non-windows nodes were 11MB whereas the .git folder on Windows was 1.9GB. Our Windows agents are connected over ssh (Cygwin). The Remote Root is on C:\ (windows style path) and the reference repository is also on C:\. We use the Checkout/SCM pipeline step in order to take advantage of extra options not available using the Git step. This is a simplified snippet of what we use I pulled from the Syntax generator. checkout([ $class: 'GitSCM', branches: [[name: '$BRANCH']], doGenerateSubmoduleConfigurations: false, extensions: [[$class: 'CloneOption', depth: 0, noTags: false, reference: '$REFERENCE_REPO', shallow: false]], gitTool: 'Default', submoduleCfg: [], userRemoteConfigs: [[url: '$REPO']]]) The console output tries to convince me it's using the reference repo but it appears it isn't (3:20 to fetch). 00:41:39.279 Cloning the remote Git repository 00:41:39.355 Cloning repository https://github.com/***/***.git 00:41:39.368 > git init C:\Users\jenkins\workspace\Build # timeout=10 00:41:39.574 Using reference repository: C:\repo_cache 00:41:39.574 Fetching upstream changes from https://github.com/***/***.git 00:41:39.574 > git --version # timeout=10 00:41:39.606 > git fetch --tags --progress https://github.com/***/***.git +refs/heads/*:refs/remotes/origin/* # timeout=30 00:45:00.369 > git config remote.origin.url https://github.com/***/***.git # timeout=10 00:45:00.431 > git config --add remote.origin.fetch +refs/heads/*:refs/remotes/origin/* # timeout=10 00:45:00.603 > git config remote.origin.url https://github.com/***/***.git # timeout=10 00:45:00.775 Fetching upstream changes from https://github.com/***/***.git 00:45:00.776 > git fetch --tags --progress https://github.com/***/***.git +refs/heads/*:refs/remotes/origin/* # timeout=30 00:45:02.416 > git rev-parse "origin/master^{commit}" # timeout=10 00:45:02.448 Checking out Revision *** (origin/master) 00:45:02.588 > git config core.sparsecheckout # timeout=10 00:45:02.619 > git checkout -f *** # timeout=30 00:46:45.479 Commit message: "Merge pull request #63 from ***/***" I've tried various things like using Windows Git to populate the reference repo, using a Jenkins git step to populate the repo, using cygwin style paths for both the ref repo location and/or the remote root dir for the agent. Not sure what else I can try but I assume its going to be something related to windows vs cygwin vs path styles vs line-endings.
