SonarQube+Swift integration: COMPILER_INDEX_STORE_ENABLE=NO' failed with error code: 66

I have been trying to implement SonarQube to implement in my Swift project. So far we have:

  1. Sonarqube is up and running, checked on localhost too.
  2. Sonar-project.properties seems to be fine, I have verified multiple times.
    When I am running ./run-sonar-swift.sh -v, I get error which is tough to understand.

Any lead to solve this would be very helpful. Thanks!!
