When renaming a variable (or other class member) Idea shows you the occurencies in a
find window.
It would be nice if Idea could (loudly or very clear) warn me if there will be any
name clashes when renaming.
For example:
public String myMethod() {
int myVariable = 0;
int myOtherVariable = 1;
System.out.println("Values: " + myVariable + ", " + myOtherVariable);
System.out.println("Method result: " + myOtherMethod());
}
Renaming "myVariable" --> "myOtherVariable" should give a warning while the scope and
usages of "myVariable" intersects with the scope of "myOtherVariable".
Renaming "myOtherMethod" --> "myMethod" should give a warning while the scope and
usages of "myOtherMethod" intersects with the scope "myMethod".
I guess this can be extended to other refactorings as well. Method signature etc.
I've encountered these clashes from time to time and it would be nice to be able to
rely on the refactorings to not infer errors.
When renaming in small projects this is not a problem to me, I've actually used the
effects to save me some work. I can, however, not think this is a wanted effect.
