How to get changes out of build (api)

Hi Yehiel, your participant would need to run after the SCM participant.  The change sets that were accepted are not directly referenced by the build (though we do link to work items associated with those change sets).  Instead, we add a contribution to the build pointing to the SCM snapshot taken after the accept.  When you click the Changes link on a build, it's actually comparing with the snapshot from the previous (non-personal) build, and delegating to the Change Explorer / Change Summary view to show the changes.

        List<IWorkItemHandle> reportedWorkItems = new ArrayList<IWorkItemHandle>();

        ILinkManager linkManager = (ILinkManager) teamRepository.getClientLibrary(ILinkManager.class);

        IReference source = linkManager.referenceFactory().createReferenceToItem(buildResultHandle);

        ILinkCollection referencesToResults = linkManager.findLinksBySource(buildLinkType, source, monitor).getAllLinksFromHereOn();

        for (Object object : referencesToResults) {

            ILink link = (ILink) object;

            IWorkItemHandle workItemHandle = (IWorkItemHandle) link.getTargetRef().resolve();

            if (workItemHandle != null) {

                reportedWorkItems.add(workItemHandle);

            }

        }

        return (IWorkItemHandle[]) reportedWorkItems.toArray(new IWorkItemHandle[reportedWorkItems.size()]);

From the other forum topic, I get the answer:

ILinkService linkService = getService(ILinkService.class);
        ILinkServiceLibrary linkLibrary = (ILinkServiceLibrary) linkService.getServiceLibrary(ILinkServiceLibrary.class);
        IReference source = linkLibrary.referenceFactory().createReferenceToItem(buildResultHandle);
        ILinkCollection referencesToResults = linkLibrary.findLinksBySource(buildLinkType, source).getAllLinksFromHereOn();
