Disable rule in sonar

In web interface for particular rule just press Deactivate button:

You have to remove this rule in the quality profile that you are using to analyse your project.

Please refer to the documentation that describes all this: Quality Profiles in Sonar.

The right way to do is to put something like this on sonar-project.properties file per project:

sonar.issue.ignore.multicriteria=e1,e2
# tab characters should not be used
sonar.issue.ignore.multicriteria.e1.ruleKey=squid:S00105
sonar.issue.ignore.multicriteria.e1.resourceKey=**/*.java
# right curly braces should be on a new line
sonar.issue.ignore.multicriteria.e2.ruleKey=squid:RightCurlyBraceStartLineCheck
sonar.issue.ignore.multicriteria.e2.resourceKey=**/*.java
