I use annotation in my code, and I try to use value which determine in run time.

I define my list as static final (lst), and I add to this list some elements.

When I use lst.get(i), I get compilation error:

The value for annotation attribute must be a constant expression

What is the solution for this issue?

The value for an annotation must be a compile time constant, so there is no simple way of doing what you are trying to do.

It is possible to use some compile time tools (ant, maven?) to config it if the value is known before you try to run the program.
