Determining Build Definitions Associated with a Specific Project Area
Using the 4.0.5 Client API's, I have a handle to a specific ProjectArea. I am having difficulty using the API's to list the names of all the Build Definitions associated with this particular Project Area. Lots of scouring of this forum and other sources have haven't helped me connect the dots yet.
Any advice and guidance is greatly appreciated.

So with all that, I ended up with this:
SubMonitor subMonitor = SubMonitor.convert(myProgressMonitor, 4);
// get the team areas for the connected project areas in the repo and
// use them to narrow the search
IProcessAreaHandle[] processAreaHandles = new IProcessAreaHandle[1];
processAreaHandles[0] = projectAreaHandle;
// create the query
IBuildDefinitionQueryModel buildDefinitionQueryModel = IBuildDefinitionQueryModel.ROOT;
final IItemQuery query = IItemQuery.FACTORY.newInstance(buildDefinitionQueryModel);
// IProjectArea extends IProcessArea
IItemHandleInputArg[] itemHandleArgs = new IItemHandleInputArg[processAreaHandles.length];
for (int i = 0; i < processAreaHandles.length; i++) {
itemHandleArgs[i] = query.newItemHandleArg();
}
IPredicate filter = ((BuildDefinitionQueryModel) buildDefinitionQueryModel).processArea()._in(itemHandleArgs);
query.filter(filter);
query.orderByDscUsingLocale(buildDefinitionQueryModel.id());
// get the results
IItemManager itemManager = repo.itemManager();
ItemQueryIterator<IBuildDefinitionHandle> iter = new ItemQueryIterator<IBuildDefinitionHandle>(
ClientFactory.getTeamBuildClient(repo), query, processAreaHandles);
LinkedList<IBuildDefinition> buildDefinitions = new LinkedList<IBuildDefinition>();
float size = iter.size(subMonitor.newChild(1));
subMonitor.setWorkRemaining((int) (3 * Math.ceil(size / IQueryService.ITEM_QUERY_MAX_PAGE_SIZE)));
while (iter.hasNext(subMonitor.newChild(1))) {
List<IBuildDefinitionHandle> definitionHandles = iter.next(IQueryService.ITEM_QUERY_MAX_PAGE_SIZE, subMonitor.newChild(1));
buildDefinitions.addAll(itemManager.fetchCompleteItemsPermissionAware(definitionHandles, IItemManager.DEFAULT, subMonitor.newChild(1)).getRetrievedItems());
}
Object[] buildsForProjectArea = buildDefinitions.toArray(new IBuildDefinition[buildDefinitions.size()]);
Compiled. No ClassCastException. Got '0'.
In debug, I learned the While loop was never executing - in-part due because the 'size' variable is set to 0. This ultimately translates to workremaining=0 after the associated calculation hits.
Unfortunately, changing the last block to remove the SubMonitor (tring to simplify this) doesn't resolve the issue as the lookup actions still returns 0. Given the system has many well-defined build definitions, there is still clearly an error in the code.
// get the results
IItemManager itemManager = repo.itemManager();
ItemQueryIterator<IBuildDefinitionHandle> iter = new ItemQueryIterator<IBuildDefinitionHandle>(
ClientFactory.getTeamBuildClient(repo), query, processAreaHandles);
LinkedList<IBuildDefinition> buildDefinitions = new LinkedList<IBuildDefinition>();
List<IBuildDefinitionHandle> definitionHandles = iter.next(IQueryService.ITEM_QUERY_MAX_PAGE_SIZE, myProgressMonitor);
buildDefinitions.addAll(itemManager.fetchCompleteItemsPermissionAware(definitionHandles, IItemManager.DEFAULT, myProgressMonitor).getRetrievedItems());
Object[] buildsForProjectArea = buildDefinitions.toArray(new IBuildDefinition[buildDefinitions.size()]);
Thanks for the assistance so far,
Jason

I've continued to study the code. It's becoming clearer, but please note the following details:
// size becomes 0
float size = iter.size(subMonitor.newChild(1));
// Evaluates to setWorkRemaining(0)
subMonitor.setWorkRemaining((int) (3 * Math.ceil(size / IQueryService.ITEM_QUERY_MAX_PAGE_SIZE)));
// Never executes because hasNext(....) returns FALSE)
while (iter.hasNext(subMonitor.newChild(1))) { // FALSE
Putting the WHILE loop aside, even a single execution returns an Iterator with 0 objects.
Could there be a bug where ProcessAreaHandles aren't handled correctly by the ItemQueryIterator?

try this one I just wrote
private static ArrayList<IBuildDefinition> getBuildDefinitionsforProjectArea(IProjectAreaHandle iprja) { Boolean allProperties = true; // allocate space for results ArrayList<IBuildDefinition> allbe = new ArrayList<IBuildDefinition>(); ITeamRepository repo= (ITeamRepository)iprja.getOrigin(); // get the data interface ITeamBuildClient buildClient = (ITeamBuildClient) repo.getClientLibrary(ITeamBuildClient.class); try { IBuildDefinitionQueryModel queryModel = IBuildDefinitionQueryModel.ROOT; // create a query for build engines IItemQuery query = IItemQuery.FACTORY.newInstance(queryModel); // allocate space for the parameter IItemHandleInputArg[] itemHandleArgs = new IItemHandleInputArg[]{query.newItemHandleArg()}; // the query filter IPredicate filter = ((BuildDefinitionQueryModel) queryModel).processArea()._in(itemHandleArgs); // set the combined filter query.filter(filter); // no parameters required IItemQueryPage queryPage = buildClient.queryItems(query, // com.ibm.team.repository.common.service.IQueryService.EMPTY_PARAMETERS, new Object[]{iprja}, IQueryService.ITEM_QUERY_MAX_PAGE_SIZE, null); // if there are build definitions defined if (queryPage.getResultSize() != 0) { while (queryPage != null) { IFetchResult fetchResult = null; if (allProperties == true) { fetchResult = repo.itemManager().fetchCompleteItemsPermissionAware(queryPage.getItemHandles(), IItemManager.DEFAULT, null); } else { final String[] all_properties = new String[] { IBuildEngine.PROPERTY_ACTIVE, IBuildEngine.PROPERTY_BUILD_ENGINE_ACTIVITY, IBuildEngine.PROPERTY_DESCRIPTION, IBuildEngine.PROPERTY_ENGINE_CONTACT_INTERVAL, IBuildEngine.PROPERTY_ID, IBuildEngine.PROPERTY_PROCESS_AREA, IBuildEngine.PROPERTY_SUPPORTED_BUILD_DEFINITIONS, IBuildEngine.PROPERTY_SUPPORTS_CANCELLATION, IBuildEngine.PROPERTY_USE_TEAM_SCHEDULER, IBuildEngine.PROPERTY_PROPERTIES, IBuildEngine.PROPERTY_CONFIGURATION_ELEMENTS }; fetchResult = repo.itemManager().fetchPartialItemsPermissionAware(queryPage.getItemHandles(), IItemManager.DEFAULT, Arrays.asList(all_properties), null); } // add these to the list allbe.addAll(fetchResult.getRetrievedItems()); if (queryPage.hasNext()) { queryPage = (IItemQueryPage) buildClient.fetchPage(queryPage.getToken(), queryPage.getNextStartPosition(), queryPage.getSize(), null); } else { queryPage = null; } } } } catch (Exception ex) { System.out.println("build exception=" + ex.getMessage()); } return allbe; } |

Thanks, Scott. I dropped in your code unmodified. The main conditional test
if (queryPage.getResultSize() != 0)
fals to pass because no records appear (getResultSize returns 0); however, I am 100% sure that the listed Project Area name is correct because A) the wrong name generates an exception message and B) the thick client shows 100+ Build Definitions when you navigate in the Team Artifacts views to <Project Area Name> -> Builds.
Again, not sure if this is a bug, but 4.0.5 is the version for both the client API's and server in-use.
Continued appreciated for the assistance,
Jason

haven't tried on 4.0.5.. have 4.0.3 and 4.0.6
try this little change.. (the 1st and last lines are the same, section in the middle changes a tiny bit ) IItemQuery query = IItemQuery.FACTORY.newInstance(queryModel); // objects of build definition type, shouldn't be needed IPredicate isBuildDefType = queryModel._isTypeOf(IBuildDefinition.ITEM_TYPE); // allocate space for the parameter IItemHandleInputArg[] itemHandleArgs = new IItemHandleInputArg[]{query.newItemHandleArg()}; // the query filter IPredicate filter = ((BuildDefinitionQueryModel) queryModel).processArea()._in(itemHandleArgs); // set the combined filter query.filter(filter._and(isBuildDefType)); // no parameters required |

I'm getting the full UNFILTERD list - independent of the Project Area. I need to know which of these BuildDefinitions are associated with ProjectArea 'ABC' vs. which ones are not.
I was originally calling .getProjectArea() on the returned result from findProcessArea(..). I've since changed that to align to your approach, but the # of items is the same (even when I restore the previous filtering code).
