title: Sonarqube - what is rule key?
body: <p>I am trying to change my Jenkins jobs regarding Sonarqube settings. So I opened my Jenkins job configuration, I am seeing something like this</p>
  
  <pre><code>sonar.issue.ignore.multicriteria=e1,e2,e3,e4,e5
  sonar.issue.ignore.multicriteria.e1.ruleKey=squid:S00112
  sonar.issue.ignore.multicriteria.e1.resourceKey=**/*.java
  </code></pre>
  
  <p>I am searching for ruleKey "squid:S00112" in Sonarqube documentation, but I am not able to find any reference regarding that.</p>
  
  <p>I need to add a few more rules to ignore. But I am unable to identify the rules rule-key values (like ruleKey=squid:S00112).  </p>
