How do I access, pipeline variables during the build process. see below. Pipeline Variable

This is what my simple test task looks like: 

 steps:
      - bash: echo "Hello World!!! - $(Build.SourceBranch) and DeployType is $(TeamsChannel)"
        displayName: "Started building for $(Build.SourceBranch)"

You should use this syntax $(VariableName) so in your case $(TeamsChannel).

You are mixing a bit tersm here. You can have few places where you can define variable:

  • pipeline variables tab
  • variable groups
  • yaml

Here you have all three cases:

variables:
- group: PROD
- name: my-bare-variable
  value: 'value of my-bare-variable'

steps:
- script: echo $(isProd) # variable defined in pipeline variables
- script: echo $(my-bare-variable) # variable defined in YAML
- script: echo $(name) # name is variable defined in PROD group
- task: Bash@3
  inputs:
    targetType: 'inline'
    script: 'env | sort'

  • it's saying command not found, if I add it in one of build task. So, like "variable groups" does it have to be referenced in variable section? if so, then how? – change198 Apr 20 '20 at 07:16

Update:

After go through your screenshot, this should be a release pipeline. (Classic UI). But what you are using for test seems to be a yaml pipeline. It's not able to access release variable from a yaml pipeline directly. You should be able to use the variable in tasks of that release pipeline.

Also take a look at this similar question. How to get the variable value in TFS/AzureDevOps from Build to Release Pipeline?

If you are not familiar with variables in Azure DevOps. Suggest you first go through our official doc-- Define variables It describe how to define/set variable, the difference of system variable, system variable, environment, variable scope, secret variable.

Besides, you could also take a look at this blog-- How to pass variables in Azure Pipelines YAML tasks which include three part:

  • Passing variables between tasks in the same job
  • Passing variables between jobs
  • Passing variables between stages

  • thanks @Patrick, this is what I wanted to know. So, in short this is available in release task but not in build . – change198 Apr 20 '20 at 10:26
