Hello everyone,
While migrating to Gradle 1.1, we noticed an issue with dynamic version resolution. Our setup is using a local fs and a remote Ivy repository defined (in this order) using RepositoryHandler's [ivy DSL]([1]http://gradle.org/docs/current/javado...). After we publish a milestone of our plugins (e.g. `1.0-m1`), we are normally also publishing an integration version (e.g. `1.0-m2-SNAPSHOT`) to the remote Ivy repository (Artifactory).

Now if a project depends on our plugin modules using `latest.milestone`, Gradle successfully downloads the `1.0-m1` version. However, if a new `1.0-m2-SNAPSHOT` is uploaded to the local fs repository, this somehow breaks the resolution and Gradle always selects this version, although it's not having a milestone status. Furthermore, it does not load its Ivy descriptor, but uses a default one (see `org.apache.ivy.plugins.resolver.BasicResolver#getDependency`).

The issue is reproducible with Gradle 1.1 and 1.2, could it be due to the fix for GRADLE-2279 :

I can provide you with a test case if needed, meanwhile here is a debug log done with Gradle 1.1 using a buildscript dependency to e.g. `org.foo:my-plugin:latest.milestone`:

In this case the local fs repository contains `1.0.0-m16-SNAPSHOT` version, while the remote http repository contains `1.0.0-m15` and `1.0.0-m16-SNAPSHOT` (and a bunch of older versions).
It is expected that the `1.0.0-m15` version is selected, but Gradle chooses `1.0.0-m16-SNAPSHOT` instead.
