Here is the code that generates the false positive:

constexpr char AUTHCODE_ACCURACYLEVEL_OPTION_RTK = 'R';

    auto receiverModelHasRTKAccuracy = [](const std::string &modelString) {
        return modelString[ConstantsNovatel::AUTHCODE_ACCURACYLEVEL_OPTION_INDICATOR] ==
               ConstantsNovatel::AUTHCODE_ACCURACYLEVEL_OPTION_RTK;
    };

Must-share information (formatted with Markdown):

  • which versions are you using (SonarQube Server / Community Build, Scanner, Plugin, and any relevant extension)
  • how is SonarQube deployed: zip, Docker, Helm
  • what are you trying to achieve
  • what have you tried so far to achieve this

Do not share screenshots of logs – share the text itself (bonus points for being well-formatted)!

Hi,

Welcome to the community!

What version of SonarQube are you seeing this in?

How can I tell what version of SonarQube I am using?

With the example code I submitted, SonarQube is saying that modelString is an unused parameter. It is being used.

Hi,

Your version is way past EOL. You should upgrade to either the latest version or the current LTA (long-term active version) at your earliest convenience. Your upgrade path is:

7.9.6 → 8.9.10 → 9.9.9 → 2025.1.1

You may find these resources helpful:

If you have questions about upgrading, feel free to open a new thread for that here.

If you can still reproduce this after you upgrade, we’d love to hear about it!

 
Thx,
Ann
