Gradle Could not find com.github.PhilJay:MPAndroidChart:v3.1.0

I have a problem I want to add com.github.PhilJay:MPAndroidChart:v3.1.0. implementation class but gradle reports that it does not find it despite the fact that I added the repositories and the class implementation in both gradle.
I have updated the version of the gradle but gradle still can't find com.github.PhilJay:MPAndroidChart:v3.1.0. implementation
Here's my project level's gradle file :

Here's my app's gradle file :
buildscript {
repositories {
google()
mavenCentral()
jcenter()
maven { url 'https://jitpack.io' }// Warning: this repository is going to shut down soon
}
dependencies{
// Add the dependency for the Google services Gradle plugin
classpath 'com.google.gms:google-services:4.3.14'
classpath 'com.github.dcendents:android-maven-gradle-plugin:2.0'
classpath 'com.android.tools.build:gradle:7.2.1'
}}
plugins {
id 'com.android.application' version '7.2.1' apply false
id 'com.android.library' version '7.2.1' apply false
id 'org.jetbrains.kotlin.android' version '1.6.10' apply false
}
task clean(type: Delete) {
delete rootProject.buildDir
}
What's the solution?

You need to add the maven { url "https://jitpack.io" } line to settings.gradle now (depending on the repositoryMode - new projects in Android Studio default to PREFER_SETTINGS, which means it looks for repositories in settings.gradle instead of the other gradle files).
For example:
dependencyResolutionManagement {
repositoriesMode.set(RepositoriesMode.PREFER_SETTINGS)
repositories {
google()
mavenCentral()
jcenter() // Warning: this repository is going to shut down soon
maven { url "https://jitpack.io" } // add this to get MPAndroidChart
}
}

I am getting lot of errors while setting up google maps API in my android Application

I am trying to integrate google maps API in my android application but getting lot of errors. I went through lot of questions online for solving the problem but couldn't find a single post which could help me.

How do I add KSP plugin to android project gradle?

My aim is to add the KSP plugin to gradle as stated in the question heading.
just go through the line below each //from quickstart comments and you'll see all the error origins.
To add the dependencies I referred the Kotlin KSP quickstart documentation.
Now, the code might not be an exact replica of the one from the docs because that didn't work and so, I attempted some failed changes to try and make it work.

Any help is appriciated.

KSP guides failed to mention where to reference your processor. Use META-INF resource directory to reference your processor processor in your processormodule:
src/main/resources/META-INF/services/com.google.devtools.ksp.processing.SymbolProcessorProvider
In this file you reference your ProcessorProvider:
com.my.package.processor.MySymbolProcessorProvider
This is important step in order your processor provider be recognized and later instantiate the actual processor.
If your dependencies setup are not in place please read further here https://medium.com/#nikoladespotoski/hands-on-google-ksp-c0508d623863

i just learnt kotlin and im trying to put my skills to practice, i created a new project and even implemented firebase authentication, now i try to creaate a new activity and im getting
java.lang.NullPointerException: Cannot get property 'kotlin_version' on null object
Error on build console. i have tried to get similar questions though none was very directly related to mine.
