Xavier Hanin commented on IVY-160:
----------------------------------
I'm not sure if and how we should fix this issue. Ivy has never been meant to
support this kind of construct: you should declare a dependency on one module
only in one dependency element. So a fix could be to raise an error in this
case, but I know that some people declare several dependencies on the same
module with different versions. I even think there is an issue for it, because
it doesn't work properly. But I don't see how and if we can really support this
kind of things.
Thoughts?
> Duplicate dependency entries within one Ivy-File not resolved correctly

> Key: IVY-160
> URL: https://issues.apache.org/jira/browse/IVY-160
> Project: Ivy
> Issue Type: Bug
> Affects Versions: 1.2, 1.3-RC1
> Environment: OS Windows
> Reporter: Nils Tegtmeier
> Assignee: Xavier Hanin
> Priority: Minor
> Fix For: 2.0
>
>
> If an ivy.xml contains more than one <dependency>-entry for the same
> organisation and module, only one of them is resolved correctly. This issue
> showed itself in two different flavors:
> a)
> Suppose you have two subsequent entries for identical configurations like
> this:
> <dependency org="foo" name="bar" rev="1.5+" >
> <conf name="runtime">
> <mapped name="*" />
> </conf>
> <artifact name="gumbo" type="zip" />
> </dependency>
> <dependency org="foo" name="bar" rev="1.5+">
> <conf name="runtime">
> <mapped name="*" />
> </conf>
> <artifact name="okra" type="jar"/>
> </dependency>
> Then the first is resolved and retrieved while the second is not.
> b)
> Suppose you have two subsequent entries for different configurations like
> this:
> <dependency org="foo" name="bar" rev="1.2.1">
> <conf name="compile">
> <mapped name="*"/>
> </conf>
> <artifact name="gumbo" type="jar"/>
> </dependency>
> <dependency org="foo" name="bar" rev="1.2.1">
> <conf name="runtime">
> <mapped name="*"/>
> </conf>
> <artifact name="okra" type="jar"/>
> </dependency>
> Then both are resolved to the configuration of the first entry if you call
> <ivy:resolve file="/ivy.xml" conf="*"/>
