Cannot import FirebaseMessagingService even with right dependecies

I'm trying to connect firebase to my app for the cloud messaging services. I made all the changes needed in gradle files that docs mentioned.
here are my grade files:
Project Level:

When I sync gradle files I get no error but when trying to import firebase like this:
import com.google.firebase.messaging.FirebaseMessagingService;
i get this error : Cannot resolve firebase
I tried cleaning and invalidating the cache(i use android studio) and resyncing gradle files but nothing helped.
and there is no other path that contains the firebase classes.
What am i doing wrong here? thanks in advance.

Could not resolve all files for configuration ':app:debugCompileClasspath' while adding a 3rd party library

I'm trying to add a library to apply page curl effect animation in android and after adding the dependency and click on sync it worked fine but when I try to run the app its giving me an error as:
Caused by: org.gradle.api.internal.artifacts.ivyservice.DefaultLenientConfiguration$ArtifactResolveException: Could not resolve all files for configuration ':app:debugCompileClasspath'.
I searched about it in google and tried different solutions like toggle offline mode and toggle online mode, adding maven { url 'https://maven.google.com' } to project level repositories but nothing worked for me.
I'm attaching the app level gradle file and project level gradle file below.
Any help would be really helpful. Thanks in advance.

Could not find method dependencyResolutionManagement() for arguments [build_ckqar66poaozqtyzw4dyn6sx4$_run_closure3#a921a13] on project app

I have a trouble in my build.gradle file because there is a method called dependencyResolutionManagement() but I don't know how to solve it.
The error says that there are not method.
This is the message:
Also I have an error that says 'Cannot Resolve symbol 'RepositoriesMode' on my build gradle.
I think I was modifying my build.gradle to add some dependence but I did something wrong. These are the message and my build.gradle file

I tried Invalidate- Restart Caché but it didn't work. I think I was modifying the build.gradle code and I made something wrong.

Try this:
Remove from your build.gradle file
repositories {
mavenCentral()
}
Add to your settings.gradle the next code section:
dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.FAIL_ON_PROJECT_REPOS)
repositories {
google()
mavenCentral()
maven { url 'https://jitpack.io' }
jcenter() // Warning: this repository is going to shut down soon
}
}
Try to sync again your project
This worked for me!!

}
Changes I made:
Removed duplicate google repo
Removed testing dependencies, as I don't think you use it.

I resolved my issue by updating my android studio to recent version.
Thanks to Khemraj for your valuable time.

This can be fixed by uncheck the offline work in settings->Build,Execution Deployment->gradle.Hope it will help for you.
