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
There are docs here on how to ignore specific rules for specific files, which links to an example of how to search for specific rules, by language. This page on baeldung goes into additional detail better than the docs
