Android Studio / Gradle is unable to properly use a library project stored in a local Sonatyp Nexus repo

Question

I'm using Android Studio 0.3.7 (latest) and Gradle 1.8. I'm currently getting the following error when I rebuild a simple test project that has a dependency on an equally simple test library project stored in a Sonotype Nexus local repository.

:UtilsUserApp:compileDefaultFlavorDebug/Users/ymedialabs/AndroidStudioProjects/UtilsUser/UtilsUserApp/src/main/java/com/ymedia/utilsuserapp/MainActivity.java:13: error: package com.ymedia.android.utils does not exist import com.ymedia.android.utils.UIUtils; ^ /Users/ymedialabs/AndroidStudioProjects/UtilsUser/UtilsUserApp/src/main/java/com/ymedia/utilsuserapp/MainActivity.java:27: error: package com.ymedia.android.utils does not exist String hello = com.ymedia.android.utils.UIUtils.getHello(); ^ 2 errors FAILED

Before reaching this stage, I was getting a different error that indicated that Gradle wasn't finding my dependency. The current message seems to indicate that I'm missing something that puts the library dependency on the project classpath.

Here's build.gradle for the APK project

buildscript {
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:0.6.+'
    }
}
apply plugin: 'android'

repositories {
    mavenCentral()
    maven {
        url = 'http://localhost:8081/nexus/content/groups/public'
    }
}

android {
    compileSdkVersion 19
    buildToolsVersion '19.0.0'

    defaultConfig {
        minSdkVersion 10
        targetSdkVersion 19
    }
    buildTypes {
        release {
            runProguard false
            proguardFile getDefaultProguardFile('proguard-android.txt')
        }
    }
    productFlavors {
        defaultFlavor {
            proguardFile 'proguard-rules.txt'
        }
    }
}

dependencies {
    compile 'com.android.support:appcompat-v7:+'
    compile 'com.ymedia:utils:1.0.0'
}

I'm using Sonatype Nexus in its out of the box configuration with this ~/.m2/settings.xml

<settings>
  <mirrors>
    <mirror>
      <!--This sends everything else to /public -->
      <id>nexus</id>

    </profile>
  </profiles>
  <activeProfiles>
    <!--make the profile active all the time -->
    <activeProfile>nexus</activeProfile>
  </activeProfiles>
</settings>

What bit of configuration is missing or in error?

Here is the output of running ./gradlew from the commandline:

I've added the recommended target to show the APK project's classpath. The artifact being loaded has a .asc extension which would explain why the jar is not being seen during the build.
