Major Description
Ivy resolution is incorrect given the following configuration:
ivy metadata of logging#slf4j;1.6.1
<ivy-module version="2.0" xmlns:extra="http://ant.apache.org/ivy/extra">

ivy metadata of logging#logback;0.9.24 ivy:

</dependencies>
</ivy-module>
Dependencies to resolve:
<dependency org="logging" name="slf4j" rev="[1.6.1, 1.6.2]" conf="runtime"/>
<dependency org="logging" name="logback" rev="[0.9.24, 0.9.25]" conf="build-tests->runtime" />
I would expect the following jars of slf4j are resolved:
slf4-api-1.6.1.jar, jcl-over-slf4j-1.6.1.jar, jul-to-slf4j-1.6.1.jar, log4j-over-slf4j-1.6.1.jar
However, only slf4j-api-1.6.1.jar is resolved.
A eclipse project is attached to demonstrate the issue.
ivy metadata for slf4j 1.6.1: repo\logging\slf4j\1.6.1\ivy.xml)
ivy metadata for logback 0.9.24: repo\logging\logback\0.9.24\ivy.xml
I've debugged through and found that VisitNode does not deal with dynamic version correctly, so that when slf4j contains extra attributes, it behaves incorrectly:
org.apache.ivy.core.resolve.VisitNode: line 286 - 302
public boolean loadData(String conf, boolean shouldBePublic) {
boolean loaded = node.loadData(
rootModuleConf, getParentNode(), parentConf, conf, shouldBePublic, getUsage());
if (loaded) {
useRealNode();
// if the loaded revision is different from original one
// we now register this node on the new resolved id
// this includes two cases:
// - the id refers to a dynamic revision, which has beenresolved by loadData
// - the loaded module descriptor has extra attributes in his info tag which are not
// used when declaring the dependency
if (data.getNode(node.getResolvedId()) == null || !data.getNode(node.getResolvedId()).getId().equals(node.getResolvedId()))
{
data.register(node.getResolvedId(), this);
/** If node's id is dynamic, e.g. logging#slf4j;[1.6.1, 1.6.2], then the VisitNode will not be associated with it because only resolvedId is considered here*/
/** The following fix associates dynamic id with VisitData as well */
/** FIX START **/
if(!node.getResolvedId().equals(node.getId()))
/** FIX END **/
}
}
return loaded;
}
I've applied this fix to handle dynamic version and then the resolution works fine.
Thanks,
