Unity Can not build when adding Ads

I have a problem for a few days that I can't solve.
When I add to my project(that work fine) a unity ads or admob using google package.
After I add one of this package and try to build my project for android I get an error with my gradle:
Exception: Gradle install not valid

I tried to download a gradle and replace it in my project but this dont solve it.
I tried copy the gradle location on the external tools and uncheck and copy the location and this not work.
I even try to open a new project using the monitaztion sample of unity and still get the same error.
Thank you.

I was with version 2021.3.16, and I try to install another version(2021.3.13) and now its work.
I Saw that the gradle is inside the unity folder so I thought that if I reinstall the unity or install another veraion it should fix it, or maybe its a bug in veraion 2021.3.16.

How to fix ''Gradle Build Failed'' on Unity?

I'm trying to build my android app for a while and can't seem to find any solution for this problem:
Image
Unity Version: Unity 2020.3.21f1 (64-bit)
JDK, SDK, NDK and Gradle used are Unity's recommended ones (already tried to use other ones).
The console details are here:

I already tried all tutorials on youtube and other forums, but every help is welcome, thanks!
Edit 1:
After trying Jaimin's solution this is happening now:
Assets/Plugins/Android\gradleTemplate.properties file is using a deprecated way of controlling which tool should be used to do the minification. To fix this, remove "useProguard" entries yourself. If not fixed, your build can fail.

And here's how the Custom Gradle Properties Template file is coded:
org.gradle.jvmargs=-Xmx**JVM_HEAP_SIZE**M
org.gradle.parallel=true
unityStreamingAssets=.unity3d**STREAMING_ASSETS**
**ADDITIONAL_PROPERTIES**

This is because android.enableR8 is deprecated. To remove it from your gradle.properties file you have to go to Project Settings > Player > Android (Tab) > Other Settings > and check Custom Gradle Properties Template.
After that, a gradleTemplate.properties file is generated at:
Assets/Plugins/Android/gradleTemplate.properties
In this file, remove line android.enableR8, or comment it out, and now make new fresh build.
This trick should work.
Alternatively, export as an Android project and then change it in Android Studio. In Android Studio, you have more control on these things.

Install a new version of Unity, it will work
You can use the Unity 2020.3.33f1 version, that's the one I use, and it works fine.
Remember to set to Preferences: Unity default JDK, Gradle, NDK

I have seen in a lot of places and the issue is really painfull. In my case, my problem it was that there was an old CSharp interface of mine incorrect that wasn't in my csproj, so I couldn't see in my Visual Studio.
As Unity doesn't care about csproj, it uses it in compilation. I just noticed because of an inexistent java issue shown in Console window (because of Android, the CSharp was converted to Java and for this reason Graddle threw the issue).
Try to find in your CSharp program some class that doesn't appear in Solution Explorer in Visual Studio and remove or fix it.
Also, I followed the fix indicated above by Jaimin. It didn't work for me, but I left like that. It makes way more sense with it.

Try This
For Windows
go to the location
"C:\Program Files\Unity\Hub\Editor\2021.1.24f1\Editor\Data\PlaybackEngines\AndroidPlayer\SDK\build-tools\31.0.0"
find a file named d8.bat. This is a Windows batch file.
rename d8.bat to dx.bat.
in the folder lib ("C:\ProgramFiles\Unity\Hub\Editor\2021.1.24f1\Editor\Data\PlaybackEngines\AndroidPlayer\SDK\build-tools\31.0.0\lib")
rename d8.jar to dx.jar
Remember AppData is a hidden folder. Turn on hidden items to see the AppData folder.
Now run your project...

Just upgrading it to Unity 2018.3.0f2 solved my problem

May be late, but I've fixed that issue by deleting the playcore.arr file from Assets/GooglePlayPlugins/com.google.play.core/Runtime/Plugins

Cause of issue: If you are using an older version of the plugin (current version 2.4), there is an issue with the Gradle file that was included (was meant for older versions of Unity). Newer versions of Unity ship with a new version of Gradle which is causing the compile errors where Unity throws an error “Unable to build gradle”.
To resolve: Open your file explorer and navigate into the project Assets > Plugins > Android and delete the mainTemplate.gradle file.

I see that this is repeated many times in the error message: "major version 52 is newer than 51, the highest major version supported by this compiler." So I'd recommend you to uninstall Android API 24 (that is Nougat) from your PC using SDK manager. Also are you using the newest Unity 5.4?

major version 52 is newer than 51, the highest major version
supported by this compiler. It is recommended that the compiler be
upgraded. 2 warnings
This means that the Java environment you currently have cannot process the Java classes in your project, since they were compiled using a higher version compiler.
In simpler terms - a class with version 52.0 was compiled with a Java 8 compiler, but your local JDK is probably of a lower version.
The simplest fix is to install JDK 8 and then set Unity to use it (Preferences -> External Toolls).
If this still does not work, you can also check out this service for fixing Android specific build issues with Unity (DISCLAIMER: the service is provided by me)
