The Attachments page allows you to specify files that will be attached to the notification message. In the Files list you can add, edit, or remove File Specifications that define the files to be attached.
Note the attached files are not captured and saved as part of the job's history. If you want to save the files, use a File Capture action instead.
If you check the Include captured console output option, any console output that has been captured for the current step (if this action is being called by a step) or for the entire job (if this action is being called by the job) will be attached to the message.
