Payam Hekmat updated IVY-1204:
------------------------------

    Attachment: ivy-1204.patch
                ivy-1204-test.patch

Tentative patch and test case for the issue. 

I'm not entirely sure if my assumptions around VisitData, VisitNode and 
ResolveData are correct, but the patch passes the Ivy tests and the attached 
case. I'd appreciate any insights here. 

> Dependency resolution fails if a dependency is resolved and a blacklisted

> Given 3 modules in the following configuration ('->' indicates a
> dependency):
> Module A: v1.0
>           v1.1
> Module B: v2.0
>             ->A v1.0
>           v2.1
>             ->A v1.0
> Module C: v3.0
>             ->A v1.0
>             ->B v2.1 
>           v3.1
>             ->A v1.1
>             ->B v2.1 (yes, C v3.1 is technically impossible to resolve)
> With an ivy file declaring the dependencies: 
>         <dependency org="foo" name="A" rev="1.+" />
>         <dependency org="foo" name="B"  rev="2.+" />
>         <dependency org="foo" name="C"  rev="3.+" />
> Using the 'latest-compatible' conflict manager, I'd expect it to resolve to A 
> v1.0, B v2.0, C v3.0, but it only resolves to B v2.1, C v3.1. If I change the 
> order of the dependency elements around (e.g. A,C,B or B,C,A), it resolves 
> correctly. In the original order, it restarts the resolve process trying to 
> handle incompatibilities between A v1.0 and A v1.1.
