Sonarqube How to supress a specific warning in Python using # NOSONAR

Question

In Python we can suppress all Sonarqube warnings at a particular line in the code by applying the # NOSONAR comment. This is not ideal. Is there a way to suppress a specific error, instead of supressing all errors?

For example, you may have a function with two warnings:

Function "foo" has 8 parameters, which is greater than the 7 authorized.
Refactor this function to reduce its Cognitive Complexity from 17 to the 15 allowed

How can you suppress the first, but not the second?

Answer 1

This is a workaround if you are using Jenkins, that isn't perfect. It can be used to suppress a specific warning for an entire file (instead of just one function).

In the Jenkins property file add something like:

sonar.issue.ignore.multicriteria=e1
sonar.issue.ignore.multicriteria.e1.ruleKey=python:S107
sonar.issue.ignore.multicriteria.e1.resourceKey=path/to/file.py

Where python:S107 is the rulekey for a function having more than 7 parameters, and path/to/file.py is the file you want to suppress this specific rule for. Unfortunately it will supress it for the entire file, as opposed to the specific function.
