Getting Bundles Containing the Issue

In this example issue key is hardcoded to "ERP-23" but in your case you will probably get the issue key from another API for example current issue inside script listener. In this example I'm converting list of component versions in the bundle to a table markup and adding it as a comment to issue.

//add bundle table as a comment to issue
def cm = ComponentAccessor.getCommentManager();
def user = ComponentAccessor.getJiraAuthenticationContext().getLoggedInUser();
cm.create(issue, user, tableMarkup.toString(), true)
