I'm using Eclipse ver 2 20011219 on Windows 2000. When trying to rename a package, changing only the case of one letter(e.g pageinfo to pageInfo) an error is thrown with only Undo or Abort options. Error message: CoreException: A resource exists with a different case: <<the absolute path of the old file follows>>
this is an instance of the file system case sensitivity issue. Moving to platform core
Get the same message when trying to rename the following packages in the Packages view: com.foo.bar to com.foo.bAr But no problems trying to rename in the Navigator view. Moving to JDT/UI for comment.
I also discovered that you can change the case of a package within the Navigator or Resource view, but references to the package within the class -- like the package statement at the top of the file -- or references to the package in other classes, are not changed. Changing the case of a package in the Package or Java view results in the error I previously reported.
Not updating the package statement when renaming in the Navigator is because the action in the navigator doesn't know about Java it is a resource only action. Since the rename works in the Navigator then we need to investigate what how it solves the case sensitivity problem.
there's not too much i can do now on the refactoring/refactoring ui side the exception comes from the fact that Core does not provide any methods to verify resource names (w.r.t. cases) see bug#6998 refactoring sits at the end of it all - i can do nothing here. the navigator uses IResource::move to rename folders jcore uses IFolder::create, which throws the exception here's the stack trace for reference: back to inbox for consideration on further action org.eclipse.jdt.core.JavaModelException[966]: org.eclipse.core.internal.resources.ResourceException: A resource exists with a different

in 2.0 your getting the error in the wizard
I was verifying another case sensitivity related bug (31820), and now I think I don't understand why the resolution to 7960 is to display an error in the rename wizard. The core provides a mechanism for a folder rename; that's how one can change case of a folder in the Navigator. I can not understand why package names should be different (unless it's simply an implementation limitation).
