Is there a way to ignore a single FindBugs warning?

With PMD, if you want to ignore a specific warning, you can use // NOPMD to have that line be ignored.

Is there something similar for FindBugs?

The FindBugs initial approach involves XML configuration files aka filters. This is really less convenient than the PMD solution but FindBugs works on bytecode, not on source code, so comments are obviously not an option. Example:

   <Class name="com.mycompany.Foo" />
   <Method name="bar" />

However, to solve this issue, FindBugs later introduced another solution based on annotations (see SuppressFBWarnings) that you can use at the class or at the method level (more convenient than XML in my opinion). Example (maybe not the best one but, well, it's just an example):

    justification="I know what I'm doing")

Note that since FindBugs 3.0.0 SuppressWarnings has been deprecated in favor of @SuppressFBWarnings because of the name clash with Java's SuppressWarnings.

Here is a more complete example of an XML filter (the example above by itself will not work since it just shows a snippet and is missing the <FindBugsFilter> begin and end tags):

        <Class name="" />
        <Method name="bar" />
        <Bug pattern="NP_BOOLEAN_RETURN_NULL" />

If you are using the Eclipse FindBugs plugin, browse to your XML filter file using Window->Preferences->Java->FindBugs->Filter files->Exclude filter files->Add.

Update Gradle

dependencies {
    compile group: 'findbugs', name: 'findbugs', version: '1.0.0'

Locate the FindBugs Report


Find the specific message

find bugs

Import the correct version of the annotation

import edu.umd.cs.findbugs.annotations.SuppressWarnings;

Add the annotation directly above the offending code


See here for more info: findbugs Spring Annotation

As others Mentioned, you can use the @SuppressFBWarnings Annotation. If you don't want or can't add another Dependency to your code, you can add the Annotation to your Code yourself, Findbugs dosn't care in which Package the Annotation is.

public @interface SuppressFBWarnings {
     * The set of FindBugs warnings that are to be suppressed in
     * annotated element. The value can be a bug category, kind or pattern.
    String[] value() default {};

     * Optional documentation of the reason why the warning is suppressed
    String justification() default "";
