Pass variable values from .yml to .json files in Azure DevOps CI/CD pipeline

Question

Greetings!!!

I'm trying to pass variable values from the below yml to json files in azure devops ci cd pipeline. Using the below code I have been trying to pass the variable values based on environment to the json file but the actual ResourceGroup value is not showing up after deployment. Still shows up as

"$(resourceGroup)"

Not sure how to address this. Please guide me in the right direction.

Here I'm trying to test out passing variable values to the .json files which are in the trigger folder. But, later extend it out to other artifacts as well.

json:

{
	"name": "myTestTrigger",
	"properties": {
		"description": "Test",
		"pipelines": [
			{
				"pipelineReference": {
					"referenceName": "myPipeline",
					"type": "PipelineReference"
				},
				"parameters": {
					"resourceGroup": "$(resourceGroup)"
				}
			}
		]
	}
}

yml:

parameters:
  - name: env
    displayName: Deploy environment
    type: string
    default: 'development'
    values:
    - development
    - test
    - preproduction
    
variables:
  - name: resourceGroup
    ${{ if eq( parameters['env'], 'development') }}:
      value: "developmentResourceGroup"
    ${{ elseif eq( parameters['env'], 'test' ) }}:
      value: "testResourceGroup"
    ${{ else }}:
      value: "preproductionResourceGroup"
  
stages:
- ${{ if eq( parameters['env'], 'development') }}:
  - stage: stage1
    jobs:
    - job: stage1job
      steps:
        - task: Bash@3
          displayName: stageselected
          inputs:
            targetType: inline
            script: |
              echo "The stage selected was stage1 as env: ${{parameters.env}} was selected and RG ${{variables.resourceGroup}"
 
- ${{ elseif eq( parameters['env'], 'test') }}:
  - stage: stage2
    jobs:
    - job: stage2job
      steps:
        - task: Bash@3
          displayName: stageselected
          inputs:
            targetType: inline
            script: |
              echo "The stage selected was stage2 as env: ${{parameters.env}} was selected and RG ${{variables.resourceGroup}}"
 
- ${{ else }}:
  - stage: stage3
    jobs:
    - job: stage3job
      steps:
        - task: Bash@3
          displayName: stageselected
          inputs:
            targetType: inline
            script: |
              echo "The stage selected was stage3 as env: ${{parameters.env}} was selected and RG ${{variables.resourceGroup}" 	

variables:
- name: resourceGroup
  value: ${{ if ("$(env)" -eq "development") }}developmentResourceGroup
         ${{ if ("$(env)" -eq "test") }}testResourceGroup
         ${{ if ("$(env)" -eq "pre-production") }}preproductionResourceGroup
        

steps:
- script: |
    echo '{ "myResourceGroup": "$(resourceGroup)" }' > $(Build.ArtifactStagingDirectory)/myTestTrigger.json
