change your mind about a file before committing it, you can delete the file, and it
will be as if it never existed: Right-click the file, and select the Delete option. In
the case of Java files, you can use the Refactor | Safe Delete option, as discussed
in chapter 9, to verify that you're removing an unused class. Upon issuing the
delete request, IDEA asks if you wish to delete the file from CVS as well, as shown
in figure 8.9. If you select the option to no longer show the dialog, the option you
select ( Delete or Don't Delete ) becomes the default behavior for IDEA . You can
later reset this setting in the CVS configuration panel.
The file is deleted from your working directory and from CVS as well if
requested. Just like when you add a file, the file isn't removed from the repository
until you commit your changes. You can un-remove the file using IDEA 's rollback
feature, discussed later in this chapter. When you commit your removals, the file
is removed from the repository.
Of course, files in CVS are never really deleted—they're moved into a hidden
archive folder called Attic and marked as deleted in the latest version. That way,
older revisions of the source tree still have access to them. Note, however, that
CVS doesn't let you delete directories; you're stuck with them. You can make them
disappear from your workspace by using the Prune Empty Directories option
when checking out your project from CVS .
Renaming, moving, and copying files
First the bad news: CVS doesn't provide rename or move facilities. If you're using
the command-line client, you have to manually copy the file to its new location or
name, add the new file to CVS , and remove the old file from CVS . Luckily, inte-
gration of CVS with IDEA 's refactoring features relieves you from the underlying
machinations. By using, for example, the Refactor | Rename refactoring, IDEA
executes any and all CVS operations required to perform the requested refactor-
ing. You can even use the Undo command to revert this change. When you com-
mit your project, the removal and addition are recorded. If you've renamed a
Java class (which results in the renaming of a Java file), IDEA 's refactoring facility
automatically corrects all the code references for you as well. The refactoring
commands Move and Copy work the same way.
