Hi,
Using Java client I can get IBuildResult instance using the Query model.
Now I want to get the build before this build.
I see a way to do it using IBuildResultStatusTrend::getPreviousBuilds
But I have no access to this class using the Client (If I am not wrong).

Is there a way to get the previous builds out of a given build?

Not sure if that will help, but I think you should be able to get the build definition and then all the build results for it. I would try that.

Thanks Ralph,

But I cannot see how get the buildResults out of the buildDefinition.

The association is only from BuildResult to BuildDefinition and not the opposite

Regarding Moti's comment above about getting the build results out of the build definition: It is possible to get the build results from the build definition. I'm including a method below that queries for a specific build using a label and build definition, but you could pull out the code related to the label:

    public IBuildResult queryForBuildUsingLabelAndBuildDefinition(String label, String buildDefinitionId, ITeamRepository teamRepository) throws TeamRepositoryException {        
        IBuildResultQueryModel buildResultQueryModel = IBuildResultQueryModel.ROOT;
        IItemQuery query = IItemQuery.FACTORY.newInstance(buildResultQueryModel);
        query.filter( query.and(buildResultQueryModel.label()._like(query.newStringArg()), buildResultQueryModel.buildDefinition()._eq(query.newItemHandleArg())));
        query.orderByDsc(buildResultQueryModel.buildStartTime());
        IProgressMonitor monitor = new NullProgressMonitor();
        ITeamBuildClient buildClient = (ITeamBuildClient) teamRepository.getClientLibrary(ITeamBuildClient.class);
        IBuildDefinition buildDefinition = buildClient.getBuildDefinition(buildDefinitionId, monitor);
        Object[] parameters = new Object[] { label, buildDefinition };    
        IItemQueryPage queryPage = buildClient.queryItems(query, parameters, IQueryService.ITEM_QUERY_MAX_PAGE_SIZE, monitor);
        if (queryPage.getSize() == 1) {
            return (IBuildResult) teamRepository.itemManager().fetchCompleteItems(queryPage.getItemHandles(), IItemManager.DEFAULT, monitor).get(0);
        }
        else {
            return null;
        }
    }

I used it to get the list of all builds in dsc order, iterating it lets me find the previous build.

Thanks,

Moti
