Can't find @Nullable inside javax.annotation.*

Question

I want use @Nullable annotation to eliminate NullPointerExceptions. I found some tutorials on the net, I noticed that this annotation comes from the package javax.annotation.Nullable; but when I import it a compilation error is generated: cannot find symbol

Answer 1

In case someone has this while trying to compile an Android project, there is an alternative Nullable implementation in android.support.annotation.Nullable. So take care which package you've referenced in your imports.

Answer 2

The artifact has been moved from net.sourceforge.findbugs to

<dependency>
    <groupId>com.google.code.findbugs</groupId>
    <artifactId>jsr305</artifactId>
    <version>3.0.0</version>
</dependency>
