Annotations

[Michael Gerz]

Hello,

there are rumours that findbugs allows using annotations for suppressing
warnings and other things. (I saw some comments in the Changelog)

Where is this feature described? I can't find it in the manual.

Regards,

Michael

Well the SuppressWarnings annotation is part of J2SE 1.5

<http://java.sun.com/j2se/1.5/docs/api/java/lang/SuppressWarnings.html>

The problem is that java.lang.SuppressWarnings has @Retention(value=SOURCE),

which means it doesn't make it into the class file. Hence FindBugs can't see it.

FindBugs defines edu.umd.cs.findbugs.annotations.SuppressWarnings

which works the same way but has @Retention(RetentionPolicy.CLASS).

FindBugs will honor this annotation, and will also honor any annotiation

named SuppressWarnings (with class retention) in any other package .

This does need be documented in the manual.

Yes, that may be working, but then You have to add a findbugs.jar to classpath, which is not what everybody would love to do :)
I've submitted a enhancement to https://sourceforge.net/tracker/index.php?func=detail&aid=2675225&group_id=96405&atid=614696
maybe someday.. ;)
