You can import a copy of an existing project into your workspace. When a project is copied, its resources are not actually copied, but are a reference to the original resource.
If you make a change to a resource in the project, for example, a service, it is changed both in the original and in the copy.
If you want a copy of a project as an archive, have the project owner export the project to a zip file outside the workspace. Then changes can be made to the working version of the project or services within the workspace. To revert to the archived copy of the project or service, delete the working copy from the workspace, including contents within the project, then unzip the project zip file into the workspace and use the Existing Project Into Workspace option of the Import wizard to import the archived copy of the project back into the workspace.
If you want only a copy of the service in a project, you must copy the entire project. If you only copy the individual service, you are copying the selected file, but not the associated hidden files required to run the service.
Copy the exported project folder into the Eclipse/ workspace folder of your installation directory.
Unzip the exported file into the workspace folder in your installation directory.
The Import wizard opens.
The imported project appears in the WorkSpace Navigator and is available for use.
