Android failed to rename aar file in build

Hi i am trying to buil and rename my aar file using gradle but get the above error:

A problem occurred evaluating project ':app'.
> Could not find property 'outputs' on BuildType_Decorated{name=variant, debuggable=false, testCoverageEnabled=false, jniDebuggable=false, pseudoLocalesEnabled=false, renderscriptDebuggable=false, renderscriptOptimLevel=3, applicationIdSuffix=null, versionNameSuffix=null, minifyEnabled=false, zipAlignEnabled=true, signingConfig=null, embedMicroApp=true, mBuildConfigFields={}, mResValues={}, mProguardFiles=[], mConsumerProguardFiles=[], mManifestPlaceholders={}}.

Here is my full build script on gradle

 apply plugin: 'com.android.library'

android.libraryVariants.all { variant ->
    def alignedOutputFile = output.outputFile
    def unalignedOutputFile = output.packageApplication.outputFile

    logger.warn('You got to variant: ' + variant + ' and output: ' + output)
    // Customise APK filenames (to include build version)
    if (variant.buildType.zipAlignEnabled) {
        // normal APK
        output.outputFile = new File(alignedOutputFile.parent, alignedOutputFile.name.replace(".aar", "-" + defaultConfig.versionName + "-" + defaultConfig.versionCode + ".aar"))
    }
    // 'unaligned' APK
    output.packageApplication.outputFile = new File(unalignedOutputFile.parent, unalignedOutputFile.name.replace(".aar", "-" + defaultConfig.versionName + "-" + defaultConfig.versionCode + ".aar"))

}

You first reference output here:
def alignedOutputFile = output.outputFile

However, you haven't declared it, which is why you get a warning that Gradle Could not find property 'output'.

You need to either loop through the outputs belonging to your variant like in this post:

android.libraryVariants.all { variant ->
    variant.outputs.each { output ->
        output.outputFile = ...        
    }
}

or fully qualify it, e.g.
def alignedOutPutFile = variant.outputs[0].outputFile

I think you might have your variant code in the wrong place. I tried the following and it worked for me:

android.applicationVariants.all { variant ->
    variant.outputs.each{ output ->
        logger.warn('You got to variant: ' + variant + ' and output: ' + output)
    }
}

I put this at a top level on the build.gradle, not under buildTypes or anything else, and I can see this:

You got to variant: com.android.build.gradle.internal.api.ApplicationVariantImpl_Decorated@3ab912fb and output: com.android.build.gradle.internal.api.ApkVariantOutputImpl_Decorated@6441365a

You got to variant: com.android.build.gradle.internal.api.ApplicationVariantImpl_Decorated@dc7d23 and output: com.android.build.gradle.internal.api.ApkVariantOutputImpl_Decorated@b9b8546

so it does find the outputs variable and iterates over it.

Edit: Since you want official sources, go to the 'Manipulating tasks' section here: http://tools.android.com/tech-docs/new-build-system/user-guide

From the site:

In Android projects, this is a bit more complicated because there could be a large number of the same task and their name is generated based on the Build Types and Product Flavors.

In order to fix this, the android object has two properties:

applicationVariants (only for the app plugin)
libraryVariants (only for the library plugin)
testVariants (for both plugins)
