                 Key: IVY-1178
                 URL: https://issues.apache.org/jira/browse/IVY-1178
             Project: Ivy
          Issue Type: Bug
          Components: Core
    Affects Versions: 2.1.0
         Environment: Linux / ant 1.7.0
            Reporter: david herviou


Originally described in ivy-user list : 
http://old.nabble.com/Transitive-resolving-issue---td27984462.html
Here just a part of the discussion that explain the problem and the temporary 
work around :
Consider the following use case :

moduleA has one of its dependencies like this : 
 <dependency org="log4j" name="log4j" rev="1.2.14" transitive="false"/> 
moduleB has one of its dependencies like this : 
 <dependency org="log4j" name="log4j" rev="1.2.15" transitive="false"/> 

While moduleC use moduleA and moduleB I have something like this : 
 <dependency org="moduleA.org" name="moduleA" rev="moduleA.rev"/> 
 <dependency org="moduleB.org" name="moduleB" rev="moduleB.rev"/> 

This seems to be very banal BUT, when running the ivy:resolve task the 
log4j-1.2.15 evicts the log4j-1.2.14 which seems to be a good thing! 
but thereafter the resolve task does not consider the transitivity has false 
and try to resolve all the dependencies of log4j-1.2.15 

If I remove moduleA.org and use only moduleB.org then the resolve task 
behave correctly (I mean there is no resolution of transitives 
dependencies). 
The reverse case is also true. 

A work-around is available by resolving conflict explicitly with something like 
:
 <conflict org="moduleA.org" module="moduleA" rev="moduleA.rev"/>
