Dave Syer updated IVY-1432:
---------------------------

    Description: 
For Maven users the local cache repo can easily contain a .pom for a dependency 
but no corresponding .jar.  Ivy treats this as a resolved dependency that does 
not exist, and hence fails, whereas it would actually be perfectly sane to skip 
it (and allow another resolver to have a go). Groovy and Gradle users 
experience this a lot (e.g. http://issues.gradle.org/browse/GRADLE-2034).

A simple workaround is to use a custom Repository in the {{localm2}} (in Groovy 
Grab terms) resolver which answers false to {{exists()}} for the .pom resource 
if the corresponding .jar is not present.
