The previous worker installed sonarqube a long time ago and didn’t update it. (5.XXX)
I’ve asked the previous worker and several people, but they answered Sonarqube is not paid version.
But strangely, the C++ project was working, I can also check the C++ rules from Sonarqube.
I don’t know the answer.
I guess the previous worker used “cppcheck” for C++ with old Sonarqube version
or
It seems that someone is lying to me. (that is old sonarqube is paid version)
What is best and simply way to find answer?
