[Bug] GitVersion produces errors on TFS 2018 and older

[conmilo]

Hi,

There is an issue calling GitVersion via command line on Azure DevOps Server (TFS) 2018 and older. Apparently these versions of TFS do not have the capability of setting output variables with the isOutput flag. See also #2426 and microsoft/azure-pipelines-agent#3284

Reproduction Steps

See Using GitVersion with the Command Line build step

Command line task calling dotnet gitversion /output buildserver /nofetch

Error Produced

Unable to process command '##vso[task.setvariable variable=GitVersion.Major;isOutput=true]0' successfully. Please reference documentation (http://go.microsoft.com/fwlink/?LinkId=817296)
Value cannot be null. (Parameter 'RefName')
Unable to process command '##vso[task.setvariable variable=GitVersion.Minor;isOutput=true]1' successfully. Please reference documentation (http://go.microsoft.com/fwlink/?LinkId=817296)
Value cannot be null. (Parameter 'RefName')
Unable to process command '##vso[task.setvariable variable=GitVersion.Patch;isOutput=true]0' successfully. Please reference documentation (http://go.microsoft.com/fwlink/?LinkId=817296)
Value cannot be null. (Parameter 'RefName')

Environment

• GitVersion 5.8.2+Branch.main.Sha.90dc2bedb08ac54498bddcc279cde5c4596a18d3
• Team Foundation Server 2017 (15.117.26714.0)

Relevant Line of Code

GitVersion/src/GitVersion.Core/BuildAgents/AzurePipelines.cs

Line 21 in 90dc2be

$"##vso[task.setvariable variable=GitVersion.{name};isOutput=true]{value}"

Workaround

Select the Control Option "Continue on error"

Still applies to GitVersion 5.9.0. Anyone have any thoughts on this?
