How to Sync Sub Tasks Using External Scripts in Jira On-premise

    This article shows how to synchronize sub-task on Jira On-premise using External scripts library.

    When syncing sub-task it's important to keep the parent-child relation. Exalate external script SubTask.groovy allows to sync sub-tasks even if the parent task is not synced yet.

    If you are sure that the parent issue is synced before sub-tasks we recommend to use a simpler configuration that works for both Jira Server and Jira Cloud.


    Let's consider you already have the Connection configured between two JIRA Instances.

    Now you need to configure sub-task synchronization: 

    Jira Server

    1. Create files from the Exalate public repository.

      We store external scripts for Jira Server in a public repository. Copy the code from the repositories below and create .groovy files. You must keep the file names as below.

    2. Upload the files to the $JIRA_HOME/scripts directory
    3. Configure Sync Rules with the scripts provided below:

    Add the snippets below to the end of the Sync Rules.

    Source side

    Outgoing sync


    Destination side

    Add the code to a new line at the bottom of the incoming sync rules block.
