Rational Team Concert™ source control includes a special operation to remove an Eclipse project from your repository workspace. The remove operation is treated like any other folder deletion and becomes part of a change set. The project will be removed from other workspaces or streams where that change set has been applied.
To remove a project from the repository:
The project is removed from the local and repository workspaces. When you deliver the resulting change set, the project is removed from the workspace flow target.
