Pass value through jobs in Azure DevOps pipeline - powershell

Question

I try to pass value through my jobs in Azure DevOps pipeline and I use for it this code:
trigger: none
pool:
vmImage: 'windows-2019'
stages:
- stage: Processing
jobs:
- job: A
steps:
- task: PowerShell#2
inputs:
targetType: 'inline'
script: |
$someValue = 1234
Write-Host ("##vso[task.setvariable variable=someValue; isOutput=true;]$someValue")
- job: B
dependsOn: ['A']
variables:
someValue: $[ dependencies.A.outputs['setVariable.someValue'] ]
steps:
- task: PowerShell#2
inputs:
targetType: 'inline'
script: |
Write-host "Hello there"
echo $(someValue)
As a result I get this:
What do I wrong? What code do I need for passing value?

Answer 1

Test your YAML sample and reproduce the same issue.
From your YAML code, it has the following issues.
1.When you set the variable in Powershell task, the command has an extra space character in the command.
Refer to the following sample to set variable:
Write-Host "##vso[task.setvariable variable=someValue;isOutput=true;]$someValue"
2.You need to define the name of the PowerShell task which is used to set the variable. Then you can use the name in next job to get the variable. name: taskname
Here is an full example:
pool:
vmImage: 'windows-2019'
stages:
- stage: Processing
jobs:
- job: A
steps:
- task: PowerShell#2
name: taskname
inputs:
targetType: 'inline'
script: |
$someValue = 1234
Write-Host "##vso[task.setvariable variable=someValue;isOutput=true;]$someValue"
- job: B
dependsOn: A
variables:
someValue: $[ dependencies.A.outputs['taskname.someValue'] ]
steps:
- task: PowerShell#2
inputs:
targetType: 'inline'
script: |
Write-host "Hello there"
echo $(someValue)
