1. right-click the project’s name in the Project Explorer 2. choose Build Configurations \> Manage… 3. use the ‘Rename…’ button to rename the active configuration 4. OK A copy of the “renamed” i [/i]configuration appears in the Project Explorer in addition to the configuration with the original name! So it’s just done a copy - not a rename! However, returning to the ‘Manage Configurations’ dialogue, it contains only the renamed version - not the original! So there’s this “orphan” configuration folder left in the Project Explorer! ---

If you rename a configuration other than the Active one, it’s worse: the Project Explorer is not updated at all - so you still see the old name, and there’s no sign of the new name! ---

Actually, the inner configuration object is indeed renamed (no duplication at this level). But it’s true that the build configuration output folder itself is not renamed (and then a new one with the new config name is created). The build configurations rename facility is implemented in the Eclipse CDT core. About the non-active configs, the new folder is not created since these output folders are created only when the corresponding configuration is active. E.g. when you create a project, only the active configuration folder is created, not the other ones. ---

But, when you create a New configuration in an existing project, its output folder does appear in the Project Explorer, but it doesn’t appear in the ‘Manage Configurations’ list until you close and re-open it! ---

The explanation of this strange behaviour: we have indeed a known GUI bug in the Manage Configurations list, which doesn’t display newly created configs until the dialog is re-opened. But since the newly created config is immediatly set as the active one, its output folder is then created on the Project Explorer.
