Multiple ClassNotFoundException after gradle build

Hi,

I'm using few plugins in my project (for example Easy Mobile, AdMob mediation etc.).
After changing Unity version from 2018.1.3f to 2018.3.14f1 I'm experiancing a lot of problems.

I've managed to figure out how to make gradle build work, but when I start the game I get multiple java.lang.ClassNotFoundException from different plugins.

Here are few examples:

There are few of those and I get more when I use Notifications from Easy Mobile etc.

I'm using latest Jar Resolver (and running it before building) not using proguard. I attatched my gradle template below.

 

I can see now, that my .apk file is 8MB smaller, than the one before Unity change.
It seems it doesn't put aar/jar files to the build.

 

and?
