Extra analysis because of sonar.binaries is required

[szapata]

Expected Behavior

When running sonar-scanner in bitbucket pipelines it should analyze only the diff / pull request.

Actual Behavior

it needs to have specified sonar.sources and sonar.binaries but it is doing extra analysis that I consider it shouldn't be doing. Is there any way to analyze only the files present in a pull request?

Plug-in version, SonarQube version, CI system, build type
