Can't see custom warnings in eclipse [message #890100]

I want to have an annotation, classes with which applied will be warned.

I followed this instruction. (since I'm not allowed to use links, the URL is misrepresented intentionally)
http : / / stackoverflow.com/questions/1752607/how-to-intentionally-cause-a-custom-java-compiler-warning-message

Now command line javac will emits the warning I want, but in eclipse, I can't see any warning symbol. I have tried turning on all warning switches in Window -> Preferences -> Java - Compiler -> Errors/Warnings.

I know Eclipse JDT has its built-in compiler, what I don't get is why it behaves differently with the javac in my OS on this.

Did you enable annotation processing on your project in Eclipse
(properties > Java Compiler > Annotation Processing)?

I use Eclipse 3.7.1 and I can't find this preference page Sad

Did a google search and I found some old articles mention it indeed.

It's a property page on your project: select the project in the Package
Explorer > context menu > Properties

Yay, found it. One more thing, does it have to be a project specific stuff? And must I explicitly tell the IDE to add custom APT jars to APT factory path rather than simply include them in build path?

Yes.

Yes, if they contain the processor(s).
