Incorrect dependency resolution when there are cyclic dependencies
------------------------------------------------------------------
Key: MNG-3486
URL: http://jira.codehaus.org/browse/MNG-3486
Project: Maven 2
Issue Type: Bug
Components: Dependencies
Affects Versions: 2.0.8, 2.1, Shared Components
Environment: Maven version: 2.0.8
Java version: 1.5.0_12
OS name: "linux" version: "2.6.17-1.2142_fc4smp" arch: "i386" Family: "unix"
Reporter: John Williams
Maven's transitive dependency algorithm fails silently when there are cycles in
the dependency graph. The symptom is that Maven sometimes fails to find all
the dependencies that it should. For instance, suppose A depends on B, B and C
depend on each other, and C depends on D. Maven will fail to discover that A
transitively depends on D.
I would expect Maven to do one of two things in this case: Either it should
find that A transitively depends on B, C, and D, or it should terminate with an
error. In either case it should report that there is a cycle involving B and C.
