Tracking in-line suppression comments

How to track the use of in-line suppression comments in the code in SonarQube Server 2026.4.

Note: For C, C++, and Objective-C, we recommend using sonar-resolve to resolve issues directly in the code rather than suppressing them with //NOSONAR. See Resolving issues in the code for more information.

Issue suppression on a specific line is possible in most languages by using the //NOSONAR comment or a comparable in-line suppression mechanism suited to the language.

To track the use of in-line suppression comments:

• For C, C++, Objective-C, PHP, T-SQL:

  • Use the rule NoSonar to track the use of the NOSONAR comment.
• For COBOL, PL/SQL:

  • Use the rule NoSonarCheck to track the use of the NOSONAR comment.
• For JavaScript, TypeScript:

  • Use the rule S1291 to track the use of the NOSONAR comment.
• For Java:

  • Use the rule S1309 to track the use of the @SuppressWarnings annotation.
• For Python:

  • Use the rule S1291 to track the use of the NOSONAR comment.
  • Use the rule S1309 to track the use of the noqa comment.
  • Use the rule S7632 to detect malformed NOSONAR and noqa comments.
