Suppressing Sonar Measurements for Designated Code Blocks

Sonar (www.sonarsource.org) is a popular tool for analyzing code and detecting potential issues. However, certain code blocks may not require Sonar's measurements, for instance, those that generate unnecessary "Preserve Stack Trace" warnings from Findbugs. This raises the question:

Can Sonar measurements be disabled for specific code blocks?

Answer:

Yes, Sonar measurements can be suppressed for designated code blocks using the SuppressWarnings annotation.

Implementation:

To suppress measurements for a specific class or method, annotate it with @java.lang.SuppressWarnings("squid_id"), where squid_id is the Sonar issue ID. For example:

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

Finding the Sonar Issue ID:

To obtain the Sonar issue ID, navigate to the Sonar UI's Issues Drilldown. Locate the issue you wish to suppress warnings for. The red issue box for your code will contain a Rule link defining the issue. Clicking this link will display the issue ID at the top of the page.
