Can You Suppress Sonar Measurements for Specific Code Blocks?

Suppressing Sonar Measurements for Specific Code Blocks

Sonar provides valuable code quality measurements, but there may be instances when you wish to exclude specific blocks of code from these measurements. This article addresses the question of whether it's possible to do so, with a specific example of suppressing the "Preserve Stack Trace" warning issued by Findbugs.

Solution: Using @SuppressWarnings Annotation

To suppress Sonar measurements for a particular class or method, you can utilize the @SuppressWarnings annotation. This annotation allows you to specify the IDs of the Sonar issues you want to ignore.

For instance, to suppress the "Preserve Stack Trace" warning (Sonar issue ID: "squid:S00112"), you would annotate the relevant class or method as follows:

<code class="java">@java.lang.SuppressWarnings("squid:S00112")</code>

Finding Sonar Issue IDs

To determine the issue IDs for the Sonar issues you want to suppress, navigate to the Sonar UI, select "Issues Drilldown," and identify the desired issue. Within the red issue box in your code, there should be a "Rule" link providing a definition of the issue. Clicking on the link will reveal the issue ID at the top of the page.

By incorporating the @SuppressWarnings annotation with the appropriate Sonar issue IDs, you can effectively disable the measurements for specific code blocks, allowing you to focus on other aspects of code quality.
