```

jenkins is run from the command line (java -jar .... as it is for testing purposes) on a windows machine.

GIT_SSH is set in the windows environment to GIT_SSH=c:\Program Files (x86)\PuTTY\plink.exe

The checkout is in a workflow which uses credentials (the following step)

```
checkout([$class: 'GitSCM', branches: [[name: '*/functions_timestamp']], doGenerateSubmoduleConfigurations: false, extensions: [[$class: 'CleanBeforeCheckout'], [$class: 'RelativeTargetDirectory', relativeTargetDir: 'cjp-champagne-lib']], submoduleCfg: [], userRemoteConfigs: [[credentialsId: 'github', url: 'git@​github.com:jtnord/cjp-champagne-lib.git']]])

```
