Decorators fail abruptly during compilation time.

[vishna]

One of steps to repro:

1. Decorator B static imports method from Decorator A.
2. Refactor Decorator A by moving static method to other class or just remove the method completely.
3. Compiler will now yield error as base decorator classes don't get generated. This is misleading as the reason for this failure is wrong static method import whereas all we get from the logs is error about decorator classes not being present. This is not helpful at all and you have to spend significant amounts of time to figure our where the problem lies.

Solution, if feasible, would be to always force generate base classes even if imports are incorrect, that way we can trace and fix errors more quickly.
