Cannot suppress warnings [message #507892]

Eclipse Platform Version: 3.4.2

I've tried changing the compiler compliance level to 1.5 and 1.6. In either case when I try to suppress warnings for methods that are not invoked using @SuppressWarnings("unused") I get the error, "SuppressWarnings cannot be resolved to a type"

What do I need to do to make eclipse use this annotation?

First, make sure that the project really has the right compliance: it
might have project specific compliance set which differs from the
workspace settings. Second, verify that the JRE library on the project's
Java build path is 1.5 or higher.

Thanks Dani,

I should note that I'm using eclipse with the BlackBerry JDE plugin, however this error arises even before I try to compile. Nonetheless could this be at the root of the problem?

I have verified that the project compliance is 1.5.
Project->Properties->Java Compiler

I have verified that the workspace compliance is 1.5.
Window->Preferences->Java->Compiler

I have verified that the installed JRE is 1.6 (jre6)
Window->Preferences->Java->Installed JREs

I still have the problem. Could the problem be related to annotation settings?

You have to make sure that the JRE 1.6 is the one that is in your
project build path:
Project->Preferences->Java Build Path->Library->JRE System Library

Thanks Mauro,

I've gotten past the initial error. Now I get the following warning, "Unnecessary @SuppressWarnings("unused")"

When I compile warnings are still output as if there was no annotation.

I'm using rapc.

Hmmm... the "Unnecessary @SuppressWarnings("unused")" error means that
you wrote a @SuppressWarnings("unused") that is useless (that is: there
are no unused variables in your class).
If you want to hide ALL the warnings, you have to use
@SuppressWarnings("all").

Hope this helps.

BlackBerry JDE doesn't support annotations, so @SuppressWarnings will not work.
