我正在尝试用另一个变量更新 azure devops 中的管道变量。 但我不确定如何做到这一点

Question

I am reading a value from.json file and storing it in a variable. Then updating this value to the pipeline variable.

$data = (Get-content -Path("C:/Desktop/file.json")).androidVersionName |Out-String

In the above cmd, I'm reading the data of androidVersionName from file.son and converting it to string data type

Write-Host "##vso[task.setVariable variable=version;]$data"

In the above cmd, I'm setting the value of pipeline variable version to the value available in data. But the value is not getting updated in powershell task of azure. Pls some one help. I'm trying this for release pipeline CD

Tried different methods suggested in comments section. Not sure why it is not getting updated in the pipeline variable section. Will there be any problem related to access? Or will it work if I add variable groups and use that?

Answer 1

Can you check this line?

Write-Host "##vso[task.setVariable.variable=version;]data"

According to the documentation, you should use task.setVariable variable=version instead of task.setVariable.variable=version : Set variables in scripts

Examples:

Write-Host "##vso[task.setvariable variable=sauce]crushed tomatoes"
Write-Host "##vso[task.setvariable variable=secret.Sauce;issecret=true]crushed tomatoes with garlic"
Write-Host "##vso[task.setvariable variable=myOutputVar;isOutput=true]this is the value"

Additionally, check your Get-Content , you should convert your json string..... as example

$data = Get-content -Path("C:/Desktop/file.json")| ConvertFrom-Json
$version = $data.androidVersionName

Write-Host "##vso[task.setVariable variable=version]$version"

Answer 2

echo "##vso[task.setvariable variable=myvar]Get-content -Path("C:/Desktop/file.json").androidVersionName |Out-String" --> tried this code and it worked like a charm
