[SOLVED] Sonar Qube for Ubuntu scans .NET project with success but no issues analyzed

Issue

I configured the MSBuild for Sonar Scanner and Sonar Scanner itself on Ubuntu, after banging my head on wall many times in many days yielded some fruitful results so that I am able to scan the .NET project on Ubuntu it did not shows any error begin step is fine, build is also successful and it says it is collecting analysis report and finished … but no report is generated I am sure there are issues because for testing I passed the vulnerable project to scanner. The version information is following

1. SonarQube-8.6.1.40680
2. Sonar Scanner 4.6.1.2450
3. Ubuntu 20.04.2 LTS
4. .NET Core 5.0.301

The command that was used to initiate the scanning is following

dotnet sonarscanner begin /k:"'myProjectKey'" /d:sonar.host.url="http://localhost:9000"
dotnet build "myProject.sln"
dotnet sonarscanner end

The output of the sonar scanner is following

please suggest a solution by keeping in view that no admin panel is accessible in command line, so prefer a way e.g. sonar.properties file or any other configuration file change would be best.

Solution

Finally i found the solution my self after lot of experiments and search hope it will help others, Basically carefully observing the logs i noticed the following lines

INFO: Indexing files of module 'VulnerableCoreApp.sln'
INFO: Base dir: ./
INFO: 0 files indexed
INFO: 72 files ignored because of scm ignore settings

Which says that SCM (Source Control Management) is excluding all files for scanning, in sonar SCM used to either include or exclude files for scanning based on version control rules defined in the settings, in my case I was not interested to use SCM in the scanning so I disabled it, to include all files for scanning.

The command line switch did it all for me, you can also specify the switch in properties file of sonar project

-Dsonar.scm.disabled=True

The command now becomes

dotnet sonarscanner begin /k:"'myProjectKey'" /d:sonar.host.url="http://localhost:9000" /d:sonar.scm.disabled=True
dotnet build "myProject.sln"
dotnet sonarscanner end

Now all files are indexed for scanning and none of the files are ignored as SCM is now disabled, if you do want to use SCM then you have to change your SCM settings in sonar admin dashboard to address this issue.
