  2. You will get a second Jenkins URL field. Enter the URL for your Jenkins instance and the Repository URL that you configured Jenkins to use. You can use the dropdown to get the clone URL for each supported protocol. Afterwards, feel free to change it to match your Jenkins instance. Make sure you include the {repository} field so Jenkins knows where to add repository id for the URL.
