Multiple errors: Gradle/SDK/JDK related. Unity android build

Question

I'm experiencing a number of Gradle errors while trying to build an android videogame.

The original error was about the corrupted Build Tools revision 31.0.0. I followed a guide that was saying: simply uninstal api 31 in the android studio and use api 30. I did so, and now the errors are in the same number but slightly different. I've reinstalled api 31 and the error did not change back to the past group. Now i'm blocked. I don't have really nothing else to say, i'm honestly miles away from my knowledge. I can't describe what is happening.

The Errors:FIRST ERROR

Hi, I got the same error I fixed by following steps. I recommend here a few things kindly check.
(1) update build tools from SDK manager from android studio to latest current is 33.x.x

(2) then fix 32.x.x at (\SDK\build-tools) build tools by following this video.

then try to build.

if you still get errors kindly share.

It may have installed features that Android Build does not support on your computer. In my case, it was solved by removing Menu, Window, Package Manager, and Post Processing. You should go over Version regarding Build. Fighting.. Guy . xlxl99@naver.com From KOREA XLXL alt text

@Nekrell I had this same errror and resolved it by doing this. 1. Paste this file (dx.bat) at SDKPath/buildtools/version/ 2. Paste this file (dx.jar) at SDKPath/buildtools/version/ and SDKPath/buildtools/version/lib/

Files:link text or just google with the file name you can get it there.

I had this error often. Try the following solutions. One of them might work for you.

Try using the latest SDK
When you look through the errors you might find it saying some files are missing in a certain location. In my case, dx.bat and dx.jar seem to missing. I just googled for the file, downloaded it, and paste it into the desired location.
Sometimes if the SDK's terms and conditions haven't been accepted while downloading it, it might cause the issue(Try redownloading it through the unity hub or search for this issue in the unity forum)
