How to suppress warning for a specific method with Intellij SonarLint plugin

Question

I want to suppress the Sonar lint plugin warning for some methods.
This question is not what I want Intellij SonarLint 2.3 - ignore rule.

Currently I have to annotate the method with @SuppressWarnings("all"),which suppresses all warnings.

Well if you don't want to put the suppression in the code or in a rule on Sonar, where do you want it to go? – Eth

@dkanejs Intellij can suppress the warning using annotations like @SuppressWarnings("specific suppress id"). – Macfarlane

Ah I understand it is what you're asking now. – Eth

docs.sonarqube.org/display/PLUG/… ? – Eth

You only want to suppress warnings (related to Sonar lint) in a specific method ? You're looking for something to exist like @SuppressWarnings("sonar") – Eth

Answer 1

You can use //NOSONAR or @SuppressWarnings() but you need to specify the rule.

From the SonarQube documentation:

The //NOSONAR tag is useful to deactivate all rules at a given line but is not suitable to deactivate all rules (or only a given rule) for all the lines of a method or a class. This is why support for @SuppressWarnings("all") has been added to SonarQube.

SINCE 2.8 of Java Plugin, you can also use @SuppressWarnings annotation with a list of rule keys:

@SuppressWarnings("squid:S2078")

or

@SuppressWarnings({"squid:S2078", "squid:S2076"}).

One thing to note is that IntelliJ will generate @SuppressWarnings("ALL") which SonarLint will ignore - it has to be "all". – Bernard

Am I correct to assume there's no such capability for Python as of 2022-12-24? docs.sonarqube.org/latest/analyzing-source-code/languages/… – Semipalmate

Answer 2

This annotation for scala method helped me

object Solution {
    @SuppressWarnings(Array("scala:S3776"))
    def threeSum(nums: Array[Int]): List[List[Int]] = {
        val sortedNums = nums.sorted

UPDATE : This submenu doesn't exist on SonarLint warnings (IDEA 2020.3.3, SonarLint 4.14.2.28348).

You can Suppress an inspection in the editor it-self,

Refer to https://www.jetbrains.com/help/idea/disabling-and-enabling-inspections.html, It has various methods to get this done, there are many ways to customize the required behaviors.

That submenu doesn't exist on SonarLint warnings (IDEA 2020.3.3, SonarLint 4.14.2.28348). – Morocco

or maybe exists for Java files but not for Kotlin files – Pinery

This "Suppress for statement" is for an IntelliJ "inspection", not from the SonarLint plugin. – Arginine
