android.libraryVariants.all { variant ->
variant.outputs.all { output ->
def aar = output.outputFile
if (aar != null && aar.name.endsWith('.aar'))
{
outputFileName = "tgasdk_v${android.defaultConfig.versionName}" + '' + ENV + "${variant.buildType.name}.aar"
println(outputFileName)
}
}
}

The above settings have no work
