Hi,

Is it possible to retrieve the build history using Java API?

Actually what I am trying to do is to find the name of the snapshots created by the last two builds. So I think the first step to do that is to retrieve the build history.

Thanks
-Albin

You might want to look into this article where I get the builds https://jazz.net/library/article/807. Maybe there is something new you can reuse.

What is the issue you are seeing with your expression?

And you might want to look at this post too, because that could be what you want: http://ryehle.wordpress.com/2012/06/28/custom-build-result-pruner/

 Hi Lauren,

Thank you for your reply. I had a look into that code and I have created some code by following the examples. However it did not work for me. The code that I have today is given below. 

TeamPlatform.startup();
IProgressMonitor monitor = new NullProgressMonitor();
ITeamRepository teamRepository = login("https://localhost:9443/jazz/", "user", "password", monitor);
ITeamBuildClient buildClient = (ITeamBuildClient) teamRepository .getClientLibrary(ITeamBuildClient.class);
IBuildDefinition buildDefinition = buildClient.getBuildDefinition("RTC_Deploy", monitor);
IBuildResultQueryModel buildResultQueryModel = IBuildResultQueryModel.ROOT;
IItemQuery query = IItemQuery.FACTORY.newInstance(buildResultQueryModel);
query.filter(buildResultQueryModel._eq(buildDefinition.getItemHandle()));
query.orderByDsc(buildResultQueryModel.buildStartTime());
String[] parameters = new String[] { };
IItemQueryPage queryPage = buildClient.queryItems(query, parameters, IQueryService.ITEM_QUERY_MAX_PAGE_SIZE, monitor);
System.out.println(queryPage.getItemHandles());

What I am doing wrong with the above code?

Thanks

Hi Albin,
Can you explain how it did not work for you?

Its not retrieving any information. The list is empty.  I think there is something wrong with my query or filter.

Hi Albin,
I'm not sure offhand how much information you can get about a build using the Java API.  https://jazz.net/wiki/bin/view/Main/BuildJavaProgrammingExamples has examples of how to query for builds, which may help you get started.

Hi Albin,
Somehow I missed the notification from your last comment.  Sorry for the delay!  I think you may want to try "buildResultQueryModel.buildDefinition()._eq(query.newItemHandleArg())" instead of " buildResultQueryModel._eq(buildDefinition.getItemHandle()" .  I'm including the code from a method I have that queries for an individual build based on its label and build definition in case it helps you: 

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;
}
