To reuse a job named testJob from a referenced project named project_ref in your main job, you

need to navigate to @Referenced project, @project_ref, Job Designs, Standard, then select testJob. A

referenced project is a project that can be accessed from another project in read-only mode. You can

add a referenced project to your main project by using the Project Settings window in Talend Studio.

You can then browse the items (such as jobs, metadata, routines, etc.) of the referenced project in

the Repository tree view under the @Referenced project node. You can drag and drop any item from

the referenced project to your main job design workspace.

You do not need to use import items, create standard job, or navigate to Metadata options. These

options are not used to reuse jobs from referenced projects. The import items option is used to

import items (such as jobs, metadata, routines, etc.) from an archive file that can be exported from

another project or workspace. The create standard job option is used to create a new job with a

name and a description. The Metadata node in the Repository tree view is used to store and manage

metadata definitions for various data sources (such as databases, files, web services, etc.). Reference:
