Can you please remind what happens when the plugin sees a warning it doesn't know about in a clang report/log file ?
Does it

• skip the warning,
• error and bail out,
• transform it into a generic uncategorized sonar rule ?

Hi @johan-boule,

looking in the code:

sonar-cxx/cxx-sensors/src/main/java/org/sonar/cxx/sensors/utils/CxxIssuesReportSensor.java

Line 172 in e265c12

.forRule(RuleKey.of(getRuleRepositoryKey(), ruleId))

https://github.com/SonarSource/sonarqube/blob/83b1e2d1b7aeee70413fb705eac2592f56b2ebe1/sonar-plugin-api/src/main/java/org/sonar/api/batch/sensor/issue/NewIssue.java#L87

Save the issue. If rule key is unknown or rule not enabled in the current quality profile then a warning is logged but no exception is thrown.

Means message is skipped and you should see a warning in the scanner LOG file.

Regards,
