Synchronization between the repository and add-on will start automatically, however, reindexing may be required to manually start the synchronization process.
There are two ways to do this:
Click the view icon to see the reindex progress of the selected repository.
The add-on stores the ID of the last indexed commit for each branch. This ID is used to limit the processed data upon reindex or update. This way, only new commits will be indexed on the next synchronization.
Click the Actions icon then Reset to reset the Last Indexed date. Perform this process whenever an add-on is updated or re-installed.
The Git Add-on automatically changes the updatedDate of an issue when a Git commit is added to an issue upon reindex. When the reindex encounters a commit previously modified by the user relating to an issue, that issue will be updated.
You can enable or disable this setting in the Git Add-on General Settings screen > Jira Issue Updates.
