Could not resolve all artifacts for configuration ':firebase_core:classpath'

[adultcode]

I am facing an issue in a Flutter project while using Firebase. I have tested various methods, including changing the package version, changing the Gradle version, clearing cache, etc., but none of them worked, I even tried to add jar libs manually.

The project runs normally, but when I add the firebase_core package, I encounter the following error:

`  A problem occurred configuring project :firebase_core.
  > Could not resolve all artifacts for configuration ':firebase_core:classpath'.
   > Could not find manifest-merger-31.1.2.jar (com.android.tools.build:manifest-merger:31.1.2).
     Searched in the following locations:
