String Annotation Value that is a constant attribute [message #1758270]

Hello,

I am generating the following interface and class:

interface A {

public static final String SERVICE_NAME = "xxx.Service.A"
}

@Component(name = A.SERVICE_NAME)
class AImpl implements A {

}

In the annotation I can easily define:

@Component(name = "xxx.Service.A") by using a construct like this:

explicitValues += TypesFactory.eINSTANCE.createJvmStringAnnotationValue => [

operation = anno.members.filter(JvmOperation).findFirst[simpleName == 'name']
values += 'xxx.Service.A'
]

I am however struggling to figure out a way to generate the one above where the name is referencing a field like this:

@Component(name = A.SERVICE_NAME)

I would appreciate any help/pointers on how I can get this done.

Thank you!
Oleg

this sounds like https://bugs.eclipse.org/bugs/show_bug.cgi?id=460798 which states this as not possible yet

Out of curiosity, are there any plans to add this support in the future? Is there a way to help/contribute?

Thank you,
