Turning Sonar off for certain code

Question

Is it possible to turn off sonar  www sonarsource org  measurements for specific blocks of code  which one doesn t want to be measured   An example is the  Preserve Stack Trace  warning which Findbugs outputs   When leaving the server  I might well want to only pass the message back to the client  not including the actual exception which I just caught  if that exception is unknown to the client  because the client doesn t have the JAR in which that exception was contained for example

Use   NOSONAR  on the line you get warning if it is something you cannot help your code with  It works

I recommend you try to suppress specific warnings by using  SuppressWarnings  quot squid S2078 quot    For suppressing multiple warnings you can do it like this  SuppressWarnings   quot squid S2078 quot    quot squid S2076 quot    There is also the   NOSONAR comment that tells SonarQube to ignore all errors for a specific line  Finally if you have the proper rights for the user interface you can issue a flag as a false positive directly from the interface  The reason why I recommend suppression of specific warnings is that it s a better practice to block a specific issue instead of using   NOSONAR and risk a Sonar issue creeping in your code by accident  You can read more about this in the FAQ Edit  6 30 16 SonarQube is now called SonarLint In case you are wondering how to find the squid number  Just click on the Sonar message  ex  Remove this method to simply inherit it   and the Sonar issue will expand  On the bottom left it will have the squid number  ex  squid S1185 Maintainability  gt  Understandability  So then you can suppress it by  SuppressWarnings  quot squid S1185 quot

This is a FAQ  You can put   NOSONAR on the line triggering the warning  I prefer using the FindBugs mechanism though  which consists in adding the  SuppressFBWarnings annotation    edu umd cs findbugs annotations SuppressFBWarnings      value    NAME OF THE FINDBUGS RULE TO IGNORE       justification    Why you choose to ignore it

User · Answer

You can annotate a class or a method with SuppressWarnings   java lang SuppressWarnings  squid S00112     squid S00112 in this case is a Sonar issue ID  You can find this ID in the Sonar UI  Go to Issues Drilldown  Find an issue you want to suppress warnings on  In the red issue box in your code is there a Rule link with a definition of a given issue  Once you click that you will see the ID at the top of the page
