Question Unwanted UDP plugin not compiling

Hello, I have a project that used to have unity IAP and other services. I upgraded unity to version 2021.1.16f1 and some kind of "Unity distribution portal" service appeared. It seems to be working, but when I downloaded the repository in a different computer, it refuses to compile.
The error is:

Code (CSharp):

1. Assets\Plugins\UDP\Editor\Analytics\Common.cs(5,23): error CS0234: The type or namespace name 'Common' does not exist in the namespace 'UnityEngine.UDP' (are you missing an assembly reference?)

This error seems to disappear if I enable UDP (Which I don't want at the moment) and IAPs. But in return, I get other three errors:

Code (CSharp):

1. Assets\Plugins\UDP\Editor\Analytics\EditorAnalytcisApi.cs(12,54): error CS0117: 'BuildConfig' does not contain a definition for 'CONNECT_ENDPOINT'
2.  
3. Assets\Plugins\UDP\Editor\AppStoreOnboardApi.cs(13,57): error CS0117: 'BuildConfig' does not contain a definition for 'CLIENT_ID'
4.  
5.  
6. Assets\Plugins\UDP\Editor\AppStoreOnboardApi.cs(14,61): error CS0117: 'BuildConfig' does not contain a definition for 'CLIENT_SECRET'

I cheched the BuildConfig file and, effectively, they are different.

What am I missing here?
