When setting up multiple Maven2 projects with the dependencies specified as
version ranges, Hudson doesn't trigger downstream builds if a built version of a
dependency matches the version range as specified in the downstream project.
The above URL points to my mail in the Hudson users list archive. It describes
the setup I used to detect this defect.
From the sources: the culprit is in hudson.model.MavenModule, method
buildDependencyGraph(DependencyGraph), line 355:
MavenModule src = modules.get(d);
modules is a HashMap with ModuleDependency objects as the key. All
ModuleDependency objects in there have a normal version number since they
represent the version information from the modules themselves.
On the other hand, the lookup with ModuleDependency 'd' can contain a version
range as the version string. Since the key lookup in the Hashmap works using the
equals method of ModuleDependency, even if the range matches according the Maven
versioning concepts, there will be no match from this lookup.
I think the best way to solve this is to incorporate the usage of the following
Maven2 interface and classes:
The last class has the most interesting method ever:
I'll see if I can find the time to create a patch...
