AzureDevops : Set Ouput Variable in the same job and use it in other tasks

Motivation

while creating a build, in my workplace we usually pull all the latest changes in local and then run few git commands and then change those values in the build pipeline,

Automation:

1. Use Azure bash task to run the git commands
2. Store the results in some variables and then use that in other tasks,

How to use bash tasks to store the variable

echo "------------  Output Results ----------------"
echo "build version of the 8 characters:  ${PBuildVersionFirst} "
echo "build version with 4 character    :  ${PBuildVersionSecond} "


# here we are storing variable PBuildVersionFirst in the variable PBuildVersionFirst1 and #then use it other tasks


echo "##vso[task.setvariable variable=PBuildVersionFirst1]${PBuildVersionFirst}"
echo "##vso[task.setvariable variable=PBuildVersionFirst2]${PBuildVersionSecond}"

How to use the above variable in PowerShell Script tasks ?

Write-Host $(PBuildVersionFirst1)
Write-Host $(PBuildVersionFirst2)

How to use the above variable in bash script tasks?

echo  $(PBuildVersionFirst1)
echo  $(PBuildVersionFirst2)

Next Steps :

Use this variable in the Gradle task and then generate the build artifact :)
