Steven Schlansker created MNG-5731:
--------------------------------------
Summary: DefaultArtifactCollector loses a transitive dependency
with specific combination of versions and RUNTIME scope
Key: MNG-5731
URL: https://jira.codehaus.org/browse/MNG-5731
Project: Maven
Issue Type: Bug
Components: Dependencies
Affects Versions: 3.2.3
Environment: Mac OS 10.9, Java 8u25
Reporter: Steven Schlansker
Attachments: maven-loses-transitive-dependency.tgz
Unpack the attached test case. It is a rather large multimodule project which
looks like the following:
{code}
test:i:jar:1 (0; enabled)
test:c:jar:3:compile (1; enabled)
test:b:jar:2:compile (2; enabled)
test:e:jar:2:compile (1; enabled)
test:c:jar:2:compile (2; disabled)
test:b:jar:1:compile (3; disabled)
test:a:jar:1:compile (4; disabled)
test:h:jar:1:runtime (2; enabled)
test:g:jar:1:runtime (3; enabled)
test:a:jar:2:compile (4; disabled)
test:f:jar:1:compile (1; enabled)
test:e:jar:1:compile (2; disabled)
test:c:jar:1:compile (3; disabled)
test:d:jar:1:compile (2; enabled)
test:c:jar:2:compile (3; disabled)
test:b:jar:1:compile (4; disabled)
test:a:jar:2:compile (5; disabled)
{code}
There is a dependency chain I1 -> E2 -> H1 -> G1(runtime) -> A2
During version resolution, the G1->A2 dependency is dropped due to
checkScopeUpdate in favor of upgrading the version of B1 -> A1 into B1 -> A2,
since it has compile scope.
The B1 -> A2 dependency is later suppressed because C3 has a "nearer"
dependency on B2, tossing B1. So A2 is lost even though there is a legitimate
need for it from G1.
To reproduce:
