InvalidPluginRequestException Gradle AndroidStudio

I have imported existing android project after 2 months, and when it started to sync the gradle, it gave some strange error, because earlier the project was working properly.
The error is Caused by: org.gradle.plugin.management.internal.InvalidPluginRequestException: Plugin 'com.android.application' is already on the script classpath.
below is my gradle file :

android version : Android Studio Arctic Fox | 2020.3.1 Patch 3,
gradle version : 4.1,
Android gradle plugin version : 3.0.1

Updated to Android Studio Arctic Fox and now I get "Kotlin not configured"

I just upgraded Android Studio to the latest stable version (Arctic Fox 2020.3.1) on Mac, and now my project doesn't build. I get a "Kotlin not configured" in the IDE top bar, and in the build output I get this error:
Could not find org.jetbrains.kotlin:kotlin-android-extensions-runtime:1.5.21.
Required by:

I tried to add this dependency to the app module Gradle file, but the error remains:

I have already tried this:
Build: Clean > Build
Invalidate Caches / Restart
Any help is appreciated thanks!
UPDATE:
I solved this problem by adding back the jcenter() repository in the Project Gradle file which I removed because Android Studio marked is as "deprecated" (barred).
Now I get this other error, and I have no idea how to solve it:
Execution failed for task ':app:kaptDebugKotlin'.
> A failure occurred while executing org.jetbrains.kotlin.gradle.internal.KaptWithoutKotlincTask$KaptExecutionWorkAction
> java.lang.reflect.InvocationTargetException (no error message)
Any thoughts? Thanks again.

I did the same and got the same result, i solved it by Fil-> Sync project with gradle files

Alternatively, You can use JDK version < 16. I have changed my JDK version from 16 to 15 in Preferences>Build, Execution, Deployment> Build Tools > Gradle and that solved my problem.

Unresolved reference #HiltAndroidApp or any other Hilt annotation in Android

When I am using #HiltAndroidApp or any other Hilt annotation. It says Unresolved reference. Create annotation. I have tried re-installing Hilt but it's still not working.
I am also using Android Studio 4.0

Try the usual:
File -> Invalidate Caches / Restart ... (and click Invalidate and Restart)

From the toolbar, press 'Sync Project with Gradle Files'.
Invalidate Caches / Restart

I had the same error, and it was related to kotlin and java files with the same name.
The issue appeared after I converted a java file to kotlin in one branch, and then merged my branches, but both files remained in the project.
The error didn't show the duplicated file name, but after adding
kapt.incremental.apt=false
to "gradle.properties" as suggested by this article:
https://medium.com/#tashpemhiwa/after-a-rather-long-hiatus-without-writing-an-article-i-have-had-recent-new-inspiration-to-start-7f1f5187ba53
after disabling incremental build, the duplicate file error appeared in my build results and I knew the duplicated file name, so I removed the java file.
I enabled incremental kapt afterwards, because incremental build is faster.

It also happened when source is set like:
sourceSets {
main {
java.srcDirs += 'build/generated/data_binding_base_class_source_out/'
}
}
And there are multiple build types. Folders in data_binding_base_class_source_out intercepts and it causes the problem.
Fix:
sourceSets {
debug {
java.srcDirs += 'build/generated/data_binding_base_class_source_out/debug/'
}
release {
java.srcDirs += 'build/generated/data_binding_base_class_source_out/release/'
}
}

I've had this issue a few times.
The only thing that has worked for me is upgrading/downgrading Android Gradle Plugin. Try using 3.5.3.
In my case, I was using 3.6.0-rc02. After downgrading to 3.5.3, the issue went away.

Kotlin the compiler warning and application cannot be executed

I have a project using androidx and kotlin, I get an error message when running the application as follows:
w: JAR runtime files in the classpath should have the same version. These files were found in the classpath:
w: /Users/arjava/.gradle/caches/modules-2/files-2.1/org.jetbrains.kotlin/kotlin-stdlib-jre7/1.2.31/98678431965f7487d6dc9b399e59b6c4b3921073/kotlin-stdlib-jre7-1.2.31.jar: kotlin-stdlib-jre7 is deprecated. Please use kotlin-stdlib-jdk7 instead
and one more message directed me to the directory :
.gradle / caches / modules-2 / files-2.1 / org directory. Jetbrains.kotlin / kotlin-stdlib-jre7 / and xxxxxxx
I'm really confused about this problem, even though I don't apply jre in my app.gradle, I try to delete the files and then there will be more and more.

what made this happen?

This is how the root project's build.gradle should look alike. when I add kotlin-stdlib-jdk7, it still complains about a version mismatch; only kotlin-stdlib (without the postfix) works for me.
buildscript {
ext.kotlinVersion = "1.3.30"
repositories {
google()
jcenter()
}

classpath "com.android.tools.build:gradle:3.4.0"
classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:${kotlinVersion}"
}
}
plugins {
id "org.jetbrains.kotlin.jvm" version "1.3.30"
}
repositories {
mavenCentral()
}
dependencies {
implementation "org.jetbrains.kotlin:kotlin-stdlib:${kotlinVersion}"
}
