Hi I have a yml pipeline in azure devops.

variables:
 - name: dependencyChanged
    value: false

-stage: stage1
 jobs:
 - task: Bash@3
   inputs:
       targetType: 'inline'
       script: |
           CHANGED_FILES=$(git diff HEAD HEAD~ --name-only)
           DEPENDENCY_CHANGED=$(echo "$CHANGED_FILES" | grep -q "aml/ml_service/docker/" && echo "true" || echo "false")
           echo "##vso[task.setvariable variable=dependencyChanged=true;isOutput=true]]$DEPENDENCY_CHANGED"
           echo "Debug: adfChanged value is '${{ variables['dependencyChanged'] }}'"

-stage: stage2
 condition: and(succeeded('stage1'), eq(variables['dependencyChanged'], 'true'))
 jobs:
 .... some jobs here

The problem is:
DEPENDENCY_CHANGED is ‘true’
and dependency_change is also true becasue it is set from DEPENDENCY_CHANGED

but stage2 never gets executed, not sure why.
even if if do
echo “##vso[task.setvariable variable=dependencyChanged=true;isOutput=true]]’true'”

In summary, I want to update the pipeline variables with in different stages and access them in multiple stages.
