I'm experimenting with SonarLint for IntelliJ, but I'm a bit wary of it. It doesn't seem to be offering anything more than IntelliJ already does, and there's no way to even look at what rules it is offering, let alone change them.
Now, maybe it does add something, but, right now, I'm being spammed by false positives. Things like saying a variable is nullable when it was asserted not null in the very previous line. Is there any way to silence the false positives so I can concentrate on what's left?
