How to suppress FindBugs warnings for fields or local variables

Question

I would like to suppress FindBugs warnings for specific fields or local variables. FindBugs documents that the Target can be Type, Field, Method, Parameter, Constructor, Pac

Answer 1

@SuppressFBWarnings on a field only suppresses findbugs warnings reported for that field declaration, not every warning associated with that field.

For example, this suppresses the "Field only ever set to null" warning:

@SuppressFBWarnings("UWF_NULL_FIELD")
String s = null;

I think the best you can do is isolate the code with the warning into the smallest method you can, then suppress the warning on the whole method.

Note: @SuppressWarnings was marked deprecated in favor of @SuppressFBWarnings

Check http://findbugs.sourceforge.net/manual/filter.html#d0e2318 There is a Local tag that can be used with the Method tag. Here you can specify which bug should be excluded for a specific local variable. Example:

<FindBugsFilter>
  <Match>
        <Class name="<fully-qualified-class-name>" />
        <Method name="<method-name>" />
        <Local name="<local-variable-name-in-above-method>" />
        <Bug pattern="DLS_DEAD_LOCAL_STORE" />
  </Match>
</FindBugsFilter>
