No meta-data file or artifact found for module

My build.gradle has something that looks like:

buildscript {
//  final netflix_grpc_plugins_version = '0.1.0-rc.1.dev.7.uncommitted+create-gradle-plugins.ff4c8e2'
  final netflix_grpc_plugins_version = '0.+'

  repositories {
    ivy {
      url "${rootDir}/../../../../common/build/distIvy"
    }
    ivy {
      url "${rootDir}/../../../../client-guice/build/distIvy"
    }
    ivy {
      url "${rootDir}/../../../../proto-definition/build/distIvy"
    }
    ivy {
      url "${rootDir}/../../../../server-guice/build/distIvy"
    }
  }

  dependencies {
    classpath 'com.google.protobuf:protobuf-gradle-plugin:0.8.+'

    classpath "netflix.protoc-plugins:netflix-grpc-plugin-client-guice:${netflix_grpc_plugins_version}"
    classpath "netflix.protoc-plugins:common:${netflix_grpc_plugins_version}"
    classpath "netflix.protoc-plugins:netflix-grpc-plugin-proto-definition:${netflix_grpc_plugins_version}"
    classpath "netflix.protoc-plugins:netflix-grpc-plugin-server-guice:${netflix_grpc_plugins_version}"
  }
}

When the dynamic version is used, the build errors with:

Caused by: java.lang.ClassNotFoundException: com.netflix.grpc.gradle.GuicePluginBase

com.netflix.grpc.gradle.GuicePluginBase is defined in common.

When the exact version is used, the build succeeds. This seems to be a resolution bug. Strangely, the bug isn’t hit with anything defined in the other dependencies. common is the only one of them that isn’t a Gradle plugin so that may have something to do with it.

Double-checking the debug output, I don’t see the “No meta-data found” error for the client module:

Searching for the common dependency in the ivy.xml file for client-guice:

    <dependency org="netflix.protoc-plugins" name="common" rev="0.1.0-rc.1.dev.7.uncommitted+create-gradle-plugins.ff4c8e2" conf="runtime-&gt;default"/>

It looks like Gradle is looking for the wrong version for common.
