Jenkins Code to Connect to RTC to fetch Build Definition

Sriram Sundaresan (611) | asked Sep 08 '14, 5:47 a.m.
Hello Everyone,

I am writing a Jenkins plug-in to connect to Rational Team concert to validate and fetch source code from a Build Definition. In order to do this, I would require User ID and password as input from the user. I would like to know if there is any API for RTC which would perform this task?

Any inputs would be extremely helpful.

Sriram Sundaresan,

Is there any technical reason why you need to roll your own Jenkins plug-in for the basic activities of validating/fetching code based on a RTC Build Definition?

IBM's official Rational Team Concert plugin already integrates with a build definition to pull source, just wanted to make sure you weren't trying to write a custom one as the older versions of IBM's RTC Jenkins plugin didn't work with build definitions.

As sam detweiler already pasted, you can write all the plumbing to get that data, I also believe there is an area in the API to use/decrypt the encrypted JBE password files, that way you don't need to hardcode the user/pass inside the plugins or as args to it.

there is no 'direct' api to get the list of build engines or build definitions.. you use query for that

here is a routine I wrote to get the build definitions in a project. I assume you know how to use the plainjava api to logon, etc..

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);

            IBuildDefinitionQueryModel queryModel = IBuildDefinitionQueryModel.ROOT;
            // create a query for build engines
            IItemQuery query = IItemQuery.FACTORY.newInstance(queryModel);
            // objects of build engine type
            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
            // no parameters required
            IItemQueryPage queryPage = buildClient.queryItems(query,
            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);
                        // print out a page of IDs of the retrieved build
                        // engines
                        final String[] all_properties = new String[] {
                                IBuildEngine.PROPERTY_CONFIGURATION_ELEMENTS };

                        fetchResult = repo.itemManager().fetchPartialItemsPermissionAware(queryPage.getItemHandles(), IItemManager.DEFAULT, Arrays.asList(all_properties), null);

                    // add these to the list

                    if (queryPage.hasNext())
                        queryPage = (IItemQueryPage) buildClient.fetchPage(queryPage.getToken(), queryPage.getNextStartPosition(), queryPage.getSize(), null);
                        queryPage = null;
        catch (Exception ex)
            System.out.println("build exception=" + ex.getMessage());
        return allbe;
