In com.googlecode.androidannotations.generation.SourceCodewriter.openBinary(JPackage, String), we call javax.annotation.processing.Filer.createSourceFile(CharSequence, Element...) to generate the source files.

However, we do not give any second parameter, so the varargs is an empty array.

Here is what's said in the javadoc about this parameter :

originatingElements - type or package elements causally associated with the creation of this file, may be elided or null

I think we should actually give it a value. This would help the Eclipse compiler understand which elements are bound to which generated file. I need to check, but it may even remove the generated classes when you remove / rename a resource.
