How to get GitVersion working in Jenkins

Question

We are using jenkins pipeline (blue ocean) to build our project.

How can we get gitversion working in jenkinsfile?

When trying gitversion.exe /output buildserver: C:\jenkins\workspace\mastere809bb9e>buildtools\GitVersion\tools\GitVersion.exe /output buildserver

GitVersion requires information from the Git repository in order for it to calculate a SemVer version for your code.

To help resolve your issue, in your Jenkins pipeline I would add a step to git clone -b <branch> <remote-repo> and use this as your sources directory. (I don't use Jenkins, but I would imagine they already have a task/step/whatever that can do this.) Then you can run GitVersion and have it calculate the version of your code (making sure to follow the Jenkins Setup instructions at GitVersion).
