BillingClient 2+ isn't working

[XCarbone]

I'am using the lib with billingclient 1.2.2 and i have no probleme.
But when i try to upgrade it to 2.2.0 our 3.0.0 i got this error : Failed resolution of: Lcom/android/vending/billing/IInAppBillingService$Stub;
It's seem that google removed it, are you working on fixing it ?
