Approach to compiling all changes in dependency tree


I'm currently trying to build a plugin that takes a build's last successful date and uses it to list all changes to all snapshot dependencies (including transitive) on a single page.  I'm having trouble figuring out how to obtain the build history for a particular dependency since a given date.  I noticed that BuildHistory has methods I can use but that they are deprecated.  What is the recommended way to do this?

Any other advice on how I might approach collating this data and displaying it would be mroe than welcome.  It's intended to be a build tab.

After some more investigation, it appears that SBuild.getChanges(Date) would be appropriate, but I'm unable to find how I determine which Snapshot Dependency SBuild objects contributed to the SBuild being investigated.  Since dependencies need to be queried at the SBuildType level, how do I go about building a tree of SBuilds that contributed to a build?

There is no SBuild.getChanges(Date).  I've found much of what I need as far as SBuild dependencies in getBuildPromotion, but I still can't figure out how to start with a BuildPromotion or SBuild and find the list of changes since a particular Date.

Is there information I can get to see how the built in dependencies tab calculates its change information?

Leon, if you need to show all of the changes from the build chain (builds combined by snapshot dependencies), you can do the following:
if you have some build from the chain (SBuild), take its BuildPromotion (promotion object represents build state):

BuildPromotion promotion = build.getBuildPromotion();

// next find topmost builds from the chain, i.e. builds depending on all other builds
BuildPromotion[] tops = promotion.findTops();

// note that because of builds reusing (the same build can belong to different build chains) there can be several top promotions
// we can take the last one, by comparing promotion ids (this is a simplified approach, but I suppose it will work in your case)
BuildPromotion top = // the last top
top.getContainingChanges(); // top node changes

Then traverse all other nodes recursively using getDependencies() method and call getContainingChanges() on all of them, merge lists of changes and show them.
