Setting build number format conditionally

问题

I'm using the YML file and i'm trying to set the build number format using the following snippet, but I'm not quite sure how to get the `Build.SourceBranch' into the formatting.

I've tried to use $(Build.SourceBranch) ... (Build.SourceBranch) and Build.SourceBranch

I'm attempting to set the output to look like

20190220-create-yaml.2 etc for when it's a feature feature branch.

and just 20190220.3 when it's a master branch.

variables:
    ${{ if ne(variables['Build.SourceBranch'], 'master') }}: 
      branchSuffix: ${{ format('-{0}', $(Build.SourceBranch)) }}
    ${{ if eq(variables['Build.SourceBranch'], 'master') }}: 
      branchSuffix: ''

name: $(Date:yyyyMMdd)$(branchSuffix)$(Rev:.r)

As Lance Li mentioned, use Build.SourceBranchName instead of Build.SourceBranch. Additionally, in format function use Build.SourceBranchName variable through variables function:

variables:
    ${{ if ne(variables['Build.SourceBranchName'], 'master') }}: 
      branchSuffix: ${{ format('-{0}', variables['Build.SourceBranchName']) }}
    ${{ if eq(variables['Build.SourceBranchName'], 'master') }}: 
      branchSuffix: ''

name: $(Date:yyyyMMdd)$(branchSuffix)$(Rev:.r)

If you want to use $(Build.SourceBranch), add to comparing value refs/heads:

ne(variables['Build.SourceBranch'], 'refs/heads/master')
