Build and Run an old Android Project in Android Studio

I am given the zipped project source code of an Android project integrated to AWS services. I need to understand and be able to add some new functionalities to the app but I cannot successfully run the project in android studio. I am using Android Studio 4.1.3.
I am new to Android and AWS and I am just learning these technologies.
How and where should I start studying the code?
Also if you could help me solve the issue I am encountering in Android Studio.
I already tried killing all gradle daemons and killing all java processes but I still encounter the same issue.
Android Studio Issue
Unable to find method 'org.gradle.api.internal.file.DefaultSourceDirectorySet.(Ljava/lang/String;Ljava/lang/String;Lorg/gradle/api/internal/file/FileResolver;Lorg/gradle/api/internal/file/collections/DirectoryFileTreeFactory;)V'

Gradle's dependency cache may be corrupt (this sometimes occurs after a network connection timeout.)
Re-download dependencies and sync project (requires network)
The state of a Gradle build process (daemon) may be corrupt. Stopping all Gradle daemons may solve this problem.
Stop Gradle build processes (requires restart)
Your project may be using a third-party plugin which is not compatible with the other plugins in the project or the version of Gradle requested by the project.
In the case of corrupt Gradle processes, you can also try closing the IDE and then killing all Java processes.

You're using an old version of the AppSync SDK that is not compatible with Android Gradle Plugin 4.x / Gradle 6+. Right now, I see that you're using AGP 4.x.
See this GitHub issue for more details.
You have two options:
Use older versions of Gradle & Android Gradle Plugin. Specifically, 3.6.3 of the plugin, and 5.6.4 of Gradle.
Update your AppSync dependencies to at least 3.1+. See the setup notes in the project's README for more details.
Source: I authored the fix for this issue in the AppSync SDK.

apply these:
id 'com.android.application'
id 'kotlin-android'
id 'kotlin-android-extensions'
id 'kotlin-kapt'
id 'com.amazonaws.appsync'
instead of these:
apply plugin: 'com.android.application'
apply plugin: 'kotlin-android'
apply plugin: 'kotlin-android-extensions'
apply plugin: 'kotlin-kapt'
apply plugin: 'com.amazonaws.appsync'
if still it does not work then simple add these:
android {
compileOptions {
sourceCompatibility JavaVersion.VERSION_1_8
targetCompatibility JavaVersion.VERSION_1_8
}
kotlinOptions {
jvmTarget = '1.8'
}
}

Create new project most of the code should be obsolete. If you want to run existing code change jcenter() to mavenCentral() also check aws documentationhttps://aws.amazon.com/getting-started/hands-on/build-android-app-amplify/

ERROR: Unable to resolve dependency for ':app#debug/compileClasspath'

I am new to Android. I built a simple login activity (just created it) and it my project is giving this error:
ERROR: Unable to resolve dependency for ':app#debug/compileClasspath': Could not find any version that matches com.android.support:appcompat-v7:29.+.
I tried these solutions and they didnt work:

I don't understand how to resolve this issue considering I haven't even added question of my own. Please explain your solution step by step so I'm able to recreate to since this is literally the first project I created.

1 just figured out how to remove this Gradle error, follow the following steps.
Go to "File".
Click on Invalidate Cache/ Restart.
Again click on Invalidate Cache / Restart(On dialog window).
Let the Gradle build without any interruption
or
2
open the app.
go to gradle scripts.
then build.gradle(module:app)
finally inside dependecies type ( implementation 'com.android.support:appcompat-v7:27.+'
)

I deleted and reinstalled my android studio. The only thing that worked for me

When you are using
compileSdkVersion 29
buildToolsVersion "29.0.2"
Change
implementation 'com.android.support:appcompat-v7:29.+'
implementation 'com.android.support:design:29.+'
To
implementation 'com.google.android.material:material:1.0.0'
implementation 'androidx.legacy:legacy-support-v4:1.0.0'
implementation 'androidx.appcompat:appcompat:1.0.0'
because google has changed the support libraries for androidX
in app gradle
change
apply plugin: 'com.android.android'
to
apply plugin: 'com.android.application'

Failing on build with androidX error but I am not using androidX in project

I am trying to build but it gives me errors. I did research and tried following solutions but cant fix.

Please let me know if I missed something. And if want to devote let me know why.

First, check inside your gradle.properties, if you have
android.enableJetifier=true
android.useAndroidX=true
Then you do have androidx enabled.
Also, and this may be obvious, but clean your Gradle build with Build -> Clean Project
UPDATE WITH ANSWER
What is happening is one of your other libraries is using androidx, GLIDE FOR SURE, and maybe others.
You have two options...
Easy: Upgrade to androidx... Like why not? Totally worth it.
Hard: Downgrade your dependencies versions to pre androidX versions.

Unresolved id with Kotlin Android Extensions on Gradle 3.3.0 and Android Studio 3.3.0

After I updated my Android Studio and gradle to the version 3.3.0 I can't compile my App. The views provided by the Kotlin Android Extensions doesn't work. I am having compilations errors with 'Unresolved reference: xxx' for my all views referenced.
On previously version from gradle and Android Studio my code works.
I have tried to clean and rebuild my project, invalidate caches and restart the Android Studio and create a new project and copy and paste my code to it, but all this doesn't work.
My project .gradle contains:

Edited:
When I updated my projects dependencies, Android Studio and migrate it to use the 'androidx' some of my ids declared in layout files was deleted (I don't know why, but I think it could happened when of my actions also tried do clean the project removing unnecessary ids declaration), ids used in constraint layout wasn't deleted.

Please try as follows
File | Invalidate Caches / Restart
Deleting .idea folder
Running gradlew clean
Re-import the project
If still problem remains then just removed apply plugin: 'kotlin-android-extensions' , synchronize gradle plugin and then I added it again.

Android Gradle plugin 3.0.1 must not be applied to project

I've trying cleaning, restarting Android Studio, and stopping the daemon with gradlew --stop.

If you are creating just an app, remove apply plugin: 'com.android.library'.
If you are creating a library replace apply plugin: 'com.android.application' with apply plugin: 'com.android.library' and remove applicationId.
Refer this - Creating Android Libraries

My problem was much more silly. While doing find and replace, I had updated the versionCode to have a value in decimal.
Older values:
versionCode 253
versionName '2.53'
Newer values:
versionCode 2.54
versionName '2.54'
Having 2.54 for versionCode caused the issue. Changing that back to 254 did the trick for me!
