  - develop
  - feat/*
  - pipeline: pipeline2
  project: appcom
  source: pipeline2-api
  trigger:
  branches:
  - develop

  variables:
 - name: alias
   value: $(resources.triggeringAlias)

         script: |
         if [ "$(alias)" == "pipeline1" ]; then
           echo ("##vso[task.setvariable variable=apiname]$(resources.pipeline.pipeline1.pipelineName)")
           echo ("##vso[task.setvariable variable=dockertag]$(resources.pipeline.pipeline1.sourceCommit) | cut -c -7")
           echo ("##vso[task.setvariable variable=helmpath]P02565Mallorca/pipeline1-api")
         elif [ "$(alias)" == "pipeline2" ]; then
           echo ("##vso[task.setvariable variable=apiname]$(resources.pipeline.pipeline2.pipelineName)")
           echo ("##vso[task.setvariable variable=dockertag]$(resources.pipeline.pipeline2.sourceCommit) | cut -c -7")
           echo ("##vso[task.setvariable variable=helmpath]P02565Mallorca/pipeline2")
           fi

By reference to this doc: Set variables in scripts, below yaml should work as expected.

resources:
  pipelines:
  - pipeline: pipeline1
    project: appcom
    source: pipeline-api
    trigger:
      branches:
      - develop
      - feat/*
  - pipeline: pipeline2
    project: appcom
    source: pipeline2-api
    trigger:
      branches:
      - develop
      - feat/*
    
variables:
- name: alias
  value: $(resources.triggeringAlias)

stages:
- stage: ScanImage
  jobs:
  - job: ScanImage
    pool:
      vmImage: 'ubuntu-16.04'
    steps:
    - script: echo $(alias)

    - task: Bash@3
      inputs:
        targetType: 'inline'
        script: |
          if [ "$(alias)" == "pipeline1" ]; then
            echo "##vso[task.setvariable variable=apiname]$(resources.pipeline.pipeline1.pipelineName)"
            echo "##vso[task.setvariable variable=dockertag]$(resources.pipeline.pipeline1.sourceCommit) | cut -c -7"
            echo "##vso[task.setvariable variable=helmpath]P02565Mallorca/pipeline1-api"
          elif [ "$(alias)" = "pipeline2" ]; then
            echo "##vso[task.setvariable variable=apiname]$(resources.pipeline.pipeline2.pipelineName)"
            echo "##vso[task.setvariable variable=dockertag]$(resources.pipeline.pipeline2.sourceCommit) | cut -c -7"
            echo "##vso[task.setvariable variable=helmpath]P02565Mallorca/pipeline2-api"
          fi

    - script: echo $(dockertag)
    - script: echo $(helmpath)
    - script: echo $(apiname)

See:Resources: pipelines for more details.

Hi Edward, i followed as you mentioned and setting up branchName as variable as below echo "##vso[task.setvariable variable=branchName]$(resources.pipeline.pipeline2.sourceBranch)" but i could not use this variable in condition for as stage stages: - stage: DEV_DCR condition: and(succeeded(), or(eq(variables $(branchName), 'refs/heads/develop'), eq(variables$(branchName), 'refs/heads/release'), contains(variables$(branchName), 'refs/heads/hotfix/'), contains(variables$(branchName), 'refs/heads/bugfix/')))..... it gives error. any idea how we can use it

Edward Han-MSFT Over a year ago

You should use stageDependencies.stageName.jobName.outputs['stepName.variableName'] not variables$(branchName) in condition, see: learn.microsoft.com/en-us/azure/devops/release-notes/2020/… and learn.microsoft.com/en-us/azure/devops/pipelines/process/… for details. BTW, please file a new ticket if you have more questions with detailed information. Thanks.
