Sonar exclusions produce indexed twice error

SonarQube Cloud

The exclusion of folders produce an indexed twice error on a file that should be excluded.
Why it is indexed twice as it should be excluded from filtering?
How can I exclude a full folder and some files with that structure?

The project structure

c:\src\SonarExamples\sonarqube-scanner-msbuild
+---CSharpProject
|   +---SomeConsoleApplication
|   \---SomeConsoleApplicationTest
\---Outputs
    \---Prints
        \---SomeConsolePrints

The filter we used in our pipeline is:

variables:
  projectSourceDir: 'sonarqube-scanner-msbuild'

- task: SonarCloudPrepare@1
  inputs:
    SonarCloud: 'SonarCloud'
    organization: 'my-organization'
    scannerMode: 'MSBuild'
    projectKey: 'SonarKey'
    projectName: 'SonarExamples'
    projectVersion: '${{ parameters.ProjectVersion }}'
    extraProperties: |
      sonar.sources = $(projectSourceDir)/CSharpProject/
      sonar.exclusions = **/AssemblyInfo.cs,$(projectSourceDir)/CSharpProject/SomeConsoleApplicationTest/**/*,$(projectSourceDir)/Outputs/**/*
      sonar.cpd.exclusions=**/AssemblyInfo.cs

The result gives an error

As remark doing the same exclusions only in SonarCloud Dashboard in General Settings - Analyze Scope does the job correctly without …/App.config can’t be indexed twice.
We would like do this exclusion from source code in a way to have the history of changes.
How can we achieve that?

Found the problem. Removing sonar.sources in -task: SonarCloudPrepare fix it and build pass.
We have to use the source defined by default in SonarCloud and not the one from the SonarCloudPrepar task

  • task: SonarCloudPrepare@1
    extraProperties: |
    sonar.sources = $(projectSourceDir)/CSharpProject/
