Generated code tends to flag up in our SONAR code quality tooling for things like cyclomatic complexity. It seems that it is a recognised problem and there is support for annotation-based suppression.
I don't want to have to manually edit or annotate this code to prevent these warnings. How can I change the generated code produced by Eclipse to include say a @Generated or @SuppressWarnings("all") annotation whenever it generates code for me?
I don't think there's a central place in Eclipse config where you can specify some flags that should be added when Eclipse generates code for you.
The only way to kind-of achieve what you want is to modify each code templates of "Java > Editor > Templates" and surround them with some flags like "// SONAR-OFF" and "// SONAR-ON", and to configure the Sonar Switch-Off Violations plugin accordingly.
But:
This is quite a pain to modify all those templates (even if you'll do it only once)
This won't work for advanced code generation like for "equals" or "hashCode" method
