If your question is about SonarQube for IDE in the IntelliJ Platform, VS Code, Visual Studio, or Eclipse, please post it in that sub-category.

Otherwise, please provide:

  • Operating system: Windows
  • IDE name and flavor/env: IntelliJ Ultimate

And a thorough description of the problem / question:

When switching over enums with 2 or less values S1301 will fire and tell you to use if statements. This is a false positive because you want switch exhaustion over enums.

enum Something {
   ONE, TWO
}

var s = ONE;
switch (s) { <-- S1301 here
   case ONE -> ...;
   case TWO -> ...;
}
