Android Gradle - Buildings library module generates unexpected .aar

I am currently working on creating a multi-module project with the following structure:

Project Root
  |- app/
    |- src/
    |- build.gradle
  |- lib
    |- src/
    |- build.gradle
  |- build.gradle
  |- gradle.properties
  |- settings.gradle

      

        
        
        
      

    

While the library module is working as expected, I get the following build error for the application module:

A problem was found with the configuration of task ':app:prepareProjectRootLib10Library'.
> File 'C:\projects\Project Root\lib\build\outputs\aar\lib-1.0.aar' specified for property 'bundle' does not exist.

      

        
        
        
      

    

As far as my build script goes, I don't think there is anything wrong with my build scripts. At the same time, when I search to generate .aar

libraries for my project, instead I find a file instead lib-1.0-SNAPSHOT.aar

, which explains the problem. While manually renaming this file to match what the build script expects is fixing the problem, I need a solution that requires manual work. Is there a way to change the construction of the script so that the application module can get the library project files it needs?

If it helps, below app/build.gradle

:

apply plugin: 'com.android.application'

android {
    compileSdkVersion 20
    buildToolsVersion '20.0.0'
    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 20
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
    sourceSets {
        main {
            java.srcDirs = ['src/main/java']
            resources.srcDirs = ['src/main/resources']
            res.srcDirs = ['src/res']
            assets.srcDirs = ['src/assets']
        }
        androidTest {
            java.srcDirs = ['src/androidTest/java']
            resources.srcDirs = ['src/androidTest/resources']
            res.srcDirs = ['src/res']
            assets.srcDirs = ['src/assets']
        }
    }
    packagingOptions {
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
    }
}

dependencies {
    compile project(':lib')
    compile 'com.android.support:support-v4:20.0.0'
}

      

        
        
        
      

    

And this lib/build.gradle

:

apply plugin: 'com.android.library'

android {
    compileSdkVersion 20
    buildToolsVersion '20.0.0'
    defaultConfig {
        minSdkVersion 16
        targetSdkVersion 20
    }
    compileOptions {
        sourceCompatibility JavaVersion.VERSION_1_7
        targetCompatibility JavaVersion.VERSION_1_7
    }
    sourceSets {
        main {
            java.srcDirs = ['src/main/java']
            resources.srcDirs = ['src/main/resources']
            res.srcDirs = ['src/res']
            assets.srcDirs = ['src/assets']
        }
        androidTest {
            java.srcDirs = ['src/androidTest/java']
            resources.srcDirs = ['src/androidTest/resources']
            res.srcDirs = ['src/res']
            assets.srcDirs = ['src/assets']
        }
    }
    packagingOptions {
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
    }
}

dependencies {
    compile 'com.android.support:support-v4:20.0.0'
}
