Analysis of mixed C# & C++ application on Azure DevOps pipeline

Must-share information (formatted with Markdown):

  • which versions are you using (SonarQube, Scanner, Plugin, and any relevant extension)
    • SonarQube Developer 10.4.1
  • how is SonarQube deployed: zip, Docker, Helm
    • Zip deploy
  • what are you trying to achieve
    • Analyze solution with both C# and C++ code as part of the Azure DevOps CI pipeline (in YML)
    • This needs to function on our own hosted build agents, we do not use the Microsoft hosted build agents.
  • what have you tried so far to achieve this

I am having an issue with analysis of a project with both C# and C++, after following the documentation linked above i was able to get the project building successfully via MSBuild, running though the build wrapper downloaded from our SonarQube server. The build output is as expected, and the logs from the build stage of the pipeline show that SonarQube is detecting both the C++ and C# files to be analyzed.

However when i get to the SonarQubeAnalyze@5 task, I get the following error:

##[error]java.lang.IllegalStateException: The "build-wrapper-dump.json" file was found but 0 C/C++/Objective-C files were analyzed.

Checking the build-wrapper.log file there is an error near the end, which may be relevant but I don’t really know how to interpret this log. The only ERROR is: ERROR: error getting long path name: 123

Here are the relevant parts of the build pipeline YML showing the prepare, download of wrapper, build, test and analyze tasks.

Hello @matthew.watson, and welcome to the community,

Can you share the content of build_wrapper_output_directory (both json and log)?
If the content is sensitive, I can send you a private message.

Hi,

I would prefer to share these logs privately

Thanks

For the record, this was due to C++/CLI C++ Analysis and Common Language Runtime (CLR) Options

Yes, thank you Alejandro for the support.

I disabled CLR on all files apart from the interface between the C# and C++ where it is actually needed.

And now the scanner works correctly.
