Now, you will have the option to add SVN repositories in your JIRA instance. Click on the Add link. On the next screen, enter Display Name and Repository Root; if your SVN repository requires authentication, then enter username and password. Select Web Link as WebClient for SVN if your repository can be browsed through a browser. Finally, click on the Add button:
