It removes sonar.branch.name property in Azure Pipeline. Put it somewhere between your SonarQubePrepare and SonarQubeAnalyze tasks.

sonarqube-remove-branch-name.yml

- powershell: |
    $params = "$env:SONARQUBE_SCANNER_PARAMS" -replace '"sonar.branch.name":"[\w/,-.]*"\,?'
    Write-Host "##vso[task.setvariable variable=SONARQUBE_SCANNER_PARAMS]$params"

If anyone is looking for a non-windows variant, this works fine on ubuntu images:

- script: |
    FILTERED_PARAMS=$(echo $SONARQUBE_SCANNER_PARAMS | sed 's/"sonar.branch.name":"[^"]*"\,//g')
    echo "##vso[task.setvariable variable=SONARQUBE_SCANNER_PARAMS]$FILTERED_PARAMS"
  displayName: Filter out non-CE sonar parameters

I use powershell on Linux machines (Azure Pipelines Microsoft-managed agents) and it works well.

- script: |
    FILTERED_PARAMS=$(echo $SONARQUBE_SCANNER_PARAMS | sed 's/"sonar.branch.name":"[^"]*"\,//g')
    echo "##vso[task.setvariable variable=SONARQUBE_SCANNER_PARAMS]$FILTERED_PARAMS"

@dasMulli , for your script I would use bash instead of script because script on Windows machines uses cmd.exe and the commands from your script won't work via cmd.exe, so, there is not reason to use a generic script task.

Hello, @wilbit,
How can I use this with Mac agent?
I tried and the error was:
/Users/runner/work/_temp/ebba7608-9021-4e4f-9953-4dd7bc559b34.sh: line 1: =: command not found
/Users/runner/work/_temp/ebba7608-9021-4e4f-9953-4dd7bc559b34.sh: line 2: Write-Host: command not found

@ElaineBSchwaner , for Mac agent you better use @dasMulli 's version for Bash shell
The final version looks like this

- bash: |
    FILTERED_PARAMS=$(echo $SONARQUBE_SCANNER_PARAMS | sed 's/"sonar.branch.name":"[\w/,-.]*"\,//g')
    echo "##vso[task.setvariable variable=SONARQUBE_SCANNER_PARAMS]$FILTERED_PARAMS"
  displayName: Filter out non-CE sonar parameters
