Ошибки при переходе на android studio 3+ и gradle 4+

При попытке собрать проект получаю следующие предупреждения и ошибки:

Warning:[options] bootstrap class path not set in conjunction with -source 1.7
Warning:Exception while processing task java.io.IOException: Can't write [D:\Development\android\taxidrv_1_14_31\Taxi\build\intermediates\transforms\proguard\TaxiConfig\release\0.jar] (Can't read [D:\Development\android\taxidrv_1_14_31\osmdroid-android\libs\junit-4.12.jar(;;;;;;**.class)] (Duplicate zip entry [b/b/k.class == junit-4.12.jar:junit/framework/TestCase.class]))
Error:Execution failed for task ':Taxi:transformClassesAndResourcesWithProguardForTaxiConfigRelease'.
> Job failed, see logs for details

Требуется помощь зала, т.к. идеи закончились что можно предпринять и чем вызвано
