--------------------------------------
Update: I ran into resolution problems after wiping my .ivy2 cache, when using
the above SBT release of Ivy.

They all appear to be transitive dependencies from "org.apache.solr" -
"solr-core" - "4.7.1". It seems the Solr/Lucene POM's don't specify versions of
their dependencies, which may be a factor here.
> ModuleRules.getRule is O(n) leading to resolution slowness

>
> Key: IVY-1465
> URL: https://issues.apache.org/jira/browse/IVY-1465
> Project: Ivy
> Issue Type: Bug
> Components: Core
> Affects Versions: 2.3.0
> Environment: OpenJDK 6,7, MacOSX + Ubuntu
> Reporter: Joshua Suereth
> Priority: Minor
> Labels: performance
>
> So, for the sbt project we noticed significant resolution time improvements
> with the following patch:
> https://github.com/sbt/ivy/pull/1
> The reasoning:
> A lot of artifacts being resolved use Maven's "dependencyManagement"
> conventions
> Ivy appears to turn these into "exact matcher" rules
> A ton of resolution time is spent filtering through these rules
> The existing solution is O(n) for all overrides
> What the patch does:
> Creates a key'd store for all "exact matcher" rules
> When executing rules, ensure that we only traverse what we have to
> (non-exact, exact specific to our key and "default").
> As I said, this represents a significant speed bump for sbt builds using Ivy.
> All existing tests pass, and I think they cover this aspect of ivy pretty
> well, from what I could see.
