----------------------------------
Resolution: Not A Bug
Assignee: Benjamin Bentmann
As documented in [Introduction to the Dependency
Mechanism|http://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html],
conflict resolution uses a "nearest wins" strategy, not the newest version.
The relevant piece of the dependency tree for adam-services:
{noformat}
[INFO] rcpers:adam-services:jar:2.2-SNAPSHOT
...
[INFO] +- apireg:apireg:jar:2.13.0:compile
[INFO] | +- org.springframework:spring-core:jar:2.5.5:compile
...
[INFO] +- rcpers:rcpers-core:jar:2.2-SNAPSHOT:compile
[INFO] | +- org.springframework:spring-aop:jar:2.5.6.SEC01:compile
{noformat}
spring-core is a direct dependency of apireg and rcpers-core and since apireg
comes before rcpers-core in the dependency tree, its version of spring-core
wins the conflict resolution.
If the default conflict resolution doesn't work you, you can use
dependencyManagement inside the adam-services POM to enforce specific versions
of transitive dependencies.

> Key: MNG-4692
> URL: http://jira.codehaus.org/browse/MNG-4692
> Project: Maven 2 & 3
> Issue Type: Bug
> Components: Inheritance and Interpolation
> Affects Versions: 2.2.1
> Environment: Ubuntu Linux, JVM 1.6.0_18 OpenJdk
> Reporter: Jean-Eric Cuendet
> Assignee: Benjamin Bentmann
> Attachments: bugmaven.tar.gz

>
> I have a dependency used by 2 sub-projects (spring-core) but with 2 different
> versions (2.5.5 and 2.5.6.SEC01)
> My project which uses theses 2 sub-projects gets spring-core 2.5.5 instead of
> the more recent 2.5.6.SEC01
> I attach a test project which illustrates this case.
> To reproduce:
> 1. untar proj.tar.gz
> 2. Run ./build.sh
> 3. Have a look at the xxx-tree.log generated files
> The dep for apireg is 2.5.5 -> OK
> The dep for rcpers-core is 2.5.6.SEC01 -> OK
> The dep for adam-services is 2.5.5 -> NOK (Should be 2.5.6.SEC01 since it
> depends on rcpers-core)
