once you have the build result, you can do the following

    public IBuildResult queryForBuildUsingLastModifiedTime(Timestamp lastModified) throws TeamRepositoryException {       
        ITeamBuildClient buildClient = (ITeamBuildClient) repo.getClientLibrary(ITeamBuildClient.class);
        IBuildResultQueryModel buildResultQueryModel = IBuildResultQueryModel.ROOT;
        IItemQuery query = IItemQuery.FACTORY.newInstance(buildResultQueryModel);
        IBuildResult result = null;
       
        // Create query filter, Last Modified and tags not eq ""
        query.filter(buildResultQueryModel.modified()._gtOrEq(query.newDateTimeArg())._and(buildResultQueryModel.tags()._notEq(query.newStringArg())));
        query.orderByDsc(buildResultQueryModel.buildStartTime());
        Object[] parameters = new Object[] { lastModified,"" };
       
        // Run query and return results
        IItemQueryPage queryPage = buildClient.queryItems(query,parameters, IQueryService.ITEM_QUERY_MAX_PAGE_SIZE, MONITOR);
       
        int i = 0;
        while (i < queryPage.getSize()) {           
            IWorkItemClient workItemClient = ((IWorkItemClient) repo.getClientLibrary(IWorkItemClient.class));
            IBuildResult tmp_result = (IBuildResult) repo.itemManager().fetchCompleteItems(queryPage.getItemHandles(), IItemManager.DEFAULT, MONITOR).get(i);

            // Create profile
            ItemProfile<IDeliverable> profile = ItemProfile.<IDeliverable> createProfile(IDeliverable.ITEM_TYPE,
                    AuditablesHelper.AUDITABLE_SMALL_PROFILE).createExtension(
                    Arrays.asList(new String[] {IDeliverable.NAME_PROPERTY, IDeliverable.DESCRIPTION_PROPERTY,
                            IDeliverable.PROJECT_AREA_PROPERTY}));

           
            //IDeliverable
            List<IDeliverable> deliverables = workItemClient.findDeliverablesByArtifact(tmp_result, profile,MONITOR);
            for (int x = 0; x < deliverables.size(); x++) {
                System.out.println("deliverable: " + deliverables.get(x).getName());
                System.out.println("deliverable: " + deliverables.get(x).getItemId().getUuidValue());
            }
           
            System.out.println("label: " + tmp_result.getLabel());
            System.out.println("last modified: " + tmp_result.modified().toString()  );
            System.out.println("start time: " + Long.toString(tmp_result.getBuildStartTime()));
            System.out.println("tags: " + tmp_result.getTags());
            System.out.println("uuid: " + tmp_result.getItemId().getUuidValue());
            i++;
        }
        return result;
    }
