sonar qube error while integrating with Azure DevOps

Question

We are trying to integrate SONAR QUBE checks when the developers tries to merge to MAIN branch.

When we try to incorporate the sonar checks as part of check in policy , we get the below error

ERROR: Error during SonarScanner execution
ERROR: Validation of project reactor failed:
o To use the property "sonar.pullrequest.key" and analyze pull requests, Developer Edition or above is required. See https://redirect.sonarsource.com/doc/branches.html for more information.

ERROR:

We are using SONAR community edition. Is this integration not supported by community edition of SONAR QUBE ?

Answer 1

As it is written in Sonar Qube forum

Pull Request support requires at least the developer edition of SonarQube. If you don't want to analyze your pull requests and keep using the community edition, then simply create a second build definition without any SonarQube task, and use it in your branch strategy to build pull requests.

And also here

Pull Request analysis is available as part of Developer Edition and higher.

So you can't do this with community edition.
