Is there a workaround for java.lang.IllegalArgumentException: /std:c++23preview is not supported

SonarQube Server / Community Build

I am using sonar-scanner-6.1.0.4477-windows-x64 for my open source project.
I just upgraded my MSVC C++ compiler settings to C++23, by defining
<LanguageStandard>stdcpp23</LanguageStandard>

which is a new with Visual Studio 2022 version 17.13. At the moment this will pass /std:c++23preview on the cmd-line to cl.exe. This causes however a problem for sonarscanner:

The SonarScanner failed in the CI pipeline with:
15:57:42.355 ERROR Error during SonarScanner Engine execution

Is there a workaround for this problem?

Hey there!

What version of SonarQube are you using? You can typically find this information in the footer of your instance.

Hi Colin,
The problem is in my CI github action:
