JIRA: Target an attachment event

[Viktor Mirzoyan]

I've implemeted an issue event listener in my plugin where I can distinguish between more general types of events ( resolved, closed, updated .. etc ). I need a spcific process to occur ONLY when an attachment has been added to an issue. My problem is an attachment event is seen as an ISSUE_UPDATED event, which is failry generic considering a handful of other actions can trigger this event type. I don't want to trigger my specific process on any issue update event. Is there there a way to "filter" or distinguish an attachement event from all others?

Thanks, some of that info was a little outdated but it definitely led me in the right direction.

If anyone is looking for the same type of task, i suggest looking into the following two:

and

your INF/classes/entitydefs/entitymodel.xml file.

Here's a snippet that worked out for what I was looking for:

    private boolean isAnAttachmentEvent(IssueEvent event)
    {    	
    	boolean isAttachmentEvent = false;
    	List<GenericValue> changeItems = null;
    	
    	try {
        	GenericValue log = event.getChangeLog();
			changeItems = log.internalDelegator.findByAnd("ChangeItem",EasyMap.build("group",log.get("id")));
		} catch (GenericEntityException e) {
			System.out.println(e.getMessage());
		}
		
		if(changeItems == null) return false;
		
		Iterator<GenericValue> it = changeItems.iterator();
		while(it.hasNext()){
			String p = it.next().getString("field");
			if(p.equalsIgnoreCase("Attachment"))
				isAttachmentEvent = true;
		}
		
		return isAttachmentEvent;
    }

You should be able to get the ChangeLog for the event from IssueEvent and then scan that to see if a file was attached

Just found some example code on how to go through the change history, it may not be the most up to date but it will give you a statr: http://confluence.atlassian.com/display/JIRACOM/JiraIssueChangeHistory
