Cooking with 3rd Party plugin fails

Hello, I’m trying to cook a project in UE4.18 with the Appodeal plugin integrated (Ads monetization system). I followed the instructions the website told me, Including the permissions, setting the SDK target version and everything, but when I try to cook, it fails. What I could figure out is that is something about a POM that is not well configured, but not much more.
Here’s the Output log it gives me:


Appodeal’s SDK Integration Instructions

Hope you could help me and thank you in advance.

Newest plugin from Appodeal - 2.1.10 iOS/ 2.1.9 Android

You also need MultiDex plugin

Hi, did you solve it? If so, how?
