Summary

This article shows how to add/append Components to Issues in Jira using Automation Rules from Automation for Jira.

Environment

Jira application version (on Server/Data Center) from 8.0.0, with any version of Automation For Jira.

Solution

Basic mode

You can accomplish the task using basic mode by:

1. Selecting the Component/s field
2. Selecting "Copy from issue" on the values box
3. Proceeding to add the desired components to be added/appended to the Component/s field

Make sure that no json code is inserted on the advanced box below that, else it'll take precedence over the basic mode above.

Advanced mode

If you need to make use of the advanced mode, you can add/append components to the issue with the code below:

{
    "update": {
        "components": [{
            "add": {"name": "Name of the Component"}
        }]
    }
}

If you need to add/append multiple components at once, the below code will do:

{
    "update": {
        "components": [{
            "add": {"name": "Name of the Component"}
        }, 
        {
            "add": {"name": "Name of another Component and so on"}
        }]
    }
}
