Event [IAPEvent.PURCHASE_SUCCESS] does not dispatch when switching to Gradle 5.6.3

[hoangdung-qbt]

if (!IAP.available){
    return;
}

IAP.addEventListener(IAPEvent.PURCHASE_SUCCESS, onSuccess);         
IAP.initialize(androidLicenseKey);

function onSuccess(e:IAPEvent):Void{
  IAP.consume(e.purchase);
}

It used to work well while using gradle 2.1.0
