Gradle error in Android Studio: Could not find “com.android.tools.build:gradle:7.1.1.”-CodePudding

I am trying to import a project from Eclipse into Android Studio. In Eclipse I exported it to gradle and then imported it into Android Studio. Note: I am new to gradle and have no insight to problem. Now I get this error:

> Configure project :
    Running gradle version: 6.8

FAILURE: Build failed with an exception.

* What went wrong:
A problem occurred configuring root project 'aBooks'.
 > Could not resolve all artifacts for configuration ':classpath'.
 > Could not find com.android.tools.build:gradle:7.1.1.
 Searched in the following locations:
   - 
https://repo.maven.apache.org/maven2/com/android/tools/build/gradle/7.1.1/gradle-7.1.1.pom
 If the artifact you are trying to retrieve can be found in the repository but without metadata in 'Maven POM' format, you need to adjust the 'metadataSources { ... }' of the repository declaration.

I tried changing ‘7.1.1’ to ‘7.2’ no change. I have no clue on how to fix this. All the answers given in my searches do not match the versions here or were no help.

EDIT1: Added info. when I go to file->Project Structure & Project, I see

Note that the Gradle version is blank. If I enter 6.8 or 7.1.1 and click OK, I get the same results and then if I go back the Gradle version is blank. Gradle version 6.8 is identified at the current version(see line 2 of the error message. Don't know if this means anything. This is the list of my Gradel-6* files:

Add google() to your repositories { } block. The Android Gradle plugin is located there.
