Fail VSTS build if SonarQube fails quality gate - sonarqube

Question

We use VSTS build with standard SonarQube build steps:
SonarQube for MsBuild - Begin Analysis
... build
SonarQube for MsBuild - End Analysis
Some time after build I can see Analysis results in SonarQube - whether it Passed or Failed quality gate.
But the VSTS build is successful even if quality gate is Failed.
Is there a way to fail a VSTS build if quaility gate is failed?
Following this:
http://docs.sonarqube.org/display/SONAR/Breaking+the+CI+Build
I've tried looking for report-task.txt file, but I can't see it anywhere.
I can probably just run MSBuild.SonarQube.Runner.exe as command-line build step, as described here:
http://docs.sonarqube.org/display/SONAR/Analyzing+with+SonarQube+Scanner+for+MSBuild#AnalyzingwithSonarQubeScannerforMSBuild-AnalyzingfromtheCommandLine
But I thought I should first try standard Build Steps for SonarQube

Here is a link to failing the build on quality gate violations with 5.3 or later, it uses the SonarQube for MSBuild - Begin Analysis task

This updated task is not available with TFS 2015 Update 1 but is available in Update 2 RC1 and VSTS (VSO).

I too had this requirement to fail the Build if sonar quality gate fails. I did created a power shell task after sonarqube display task. Here is the script to find the status:
function Get-SonarQubeStatus() {
# Step 1. Create a username:password pair
$credPair = "username:password"
# Step 2. Encode the pair to Base64 string
$encodedCredentials = [System.Convert]::ToBase64String([System.Text.Encoding]::ASCII.GetBytes($credPair))
# Step 3. Form the header and add the Authorization attribute to it
$headers = #{ Authorization = "Basic $encodedCredentials" }
# Step 4. Make the GET request
$responseData = Invoke-WebRequest -Uri https://localhost/api/qualitygates/project_status?projectKey=<projectkey> -Method Get -Headers $headers -UseBasicParsing
#write-host $responseData.content
$x = $responseData.content | ConvertFrom-Json
$sonarQualityGateResult = $x.projectStatus.status
if($sonarQualityGateResult -eq "ERROR")
{
write-host "CI failed due to Sonarqube quality Gate"
exit 1
}
}
