Answer 1

I am building same app with Android Studio 3.0 on both Linux or Windows. After upgrading to Gradle 3.0.1, I had a similar issue on Windows, while it was working fine on Linux:

Error:Execution failed for task ':smsreminder:packageDebug'. > Cannot create directory C:\Users\Florent\AndroidStudioProjects\MyApp\myapp\build\outputs\apk\debug\C:\Users\Florent\AndroidStudioProjects\MyApp\myapp\build\outputs\apk\debug

And thanks to above answer from Leo, I made this more friendly apk name:

outputFileName = "${variant.name}-${variant.versionName}.apk"
=> produces: debug-x.y.apk

outputFileName = output.outputFile.name + ".${variant.versionName}.apk"
=> produces: MyAppName.x.y.apk

Otherwise, I found this working too if one want to keep default :

if (org.gradle.internal.os.OperatingSystem.current().windows)
            outputFileName = "${variant.name}-${variant.versionName}.apk"
        else
            outputFileName = new File(output.outputFile.parent, outputFileName.replace(output.outputFile.name, defaultConfig.applicationId + ".apk"))
