dependencyManagement and Manifest.MF issue

[to...@gi-de.com]

Hi, 

in our build, we have a module C with a dependeny to module B, having a 
dependency to module A in version A-4.0.14, but managed to version 
A-4.0.15.
Thus, this version and dependency is build into Manifest.MF of module C:

Class-Path: B-1.0.0-SNAPSHOT.jar A-4.0.15.jar

Later on, we pick up module C, and copy all dependencies of it into a 
directory structure - assuming, that a complete classpath will result.
When copying dependencies, not version A-4.0.15 is copied, but A-4.0.14 
(coming from module B´s dependencies).

=> We now have a runtime problem, because in Manifest.MF A-4.0.15 is 
stated, but A-4.0.14 was copied.

Any suggestions how to handle this?

Thanx, Torsten

Use a dependencyManagement section in a shared parent POM where you define 
the versions of your direct and transitive deps. NOte, that such a parent 
POM does not have to be in the parent directory, but can be an artifact on 
its own right with own release cycle.
