Why eclipse refactoring rename a variable even in different folders?

Question

I am working with Eclipse and I have a weird problem.

I have one code (let's call it A) and another copy of that code (let's call it B). A and B are one code but in different folders.

I want to keep A as original code and change some variable's name in code B.

When I change any variable's name using Refactor option in code B, it will automatically be changed in code A too!!!!

I do not want to see this change in code A, I want to compare both code in same time so I should open both of them with my Eclipse.

Look forward to your kind response,

Answer 1

Finally I found a solution for above mentioned problem ! Imagine I have to same folder with same code which are dependent together (folder A and B):

Now when I open these folders in Eclipse to work on the codes, lets call them Project A and Project B, as I mentioned I had problem with renaming the valuables in my code. Because with renaming one variables (Refactor option) in Code A, that variable will be renamed in code B automatically which I do not want it !

The simple solution is: I should just right click on Project B -> choose "close project" !

Now I can work on Project A without any influence on Code B, and when ever I need to move to Project B I need to simply write click on Project B -> choose "open project"!

It is good, because I already have two projects in my Eclipse desktop and whenever I need the using "close project" and "open project" I will active them :)

Anyway many thanks for all your helps...

If code A is dependent on that variable in code B, refactoring B should change code A as well. This is the expected scenario. So, you should first remove the dependency and then do this refactoring.

After typing the new variable name, press Esc instead of Enter. This will limit changes to the one file.
