Androidタブレットにビルドする際のGradle build failedエラーについて

Question

開発環境windowsでAndroid(バージョン10)にビルドする際に「Gradle build failed. See the Console for details」と表記されてしまします。
Unityは2021.1.10を使用し、Androidstudioは2020.3.1を使用しています。

恐らく下記の方と同じ現象かと思われます。

試したこと。
・https://teratail.com/questions/339947
と同様に、にAndroid Studio用にExportしてAndroidstudioでGradleをアップグレードした。
・ Installed Build Tools revision 31.0.0 is corrupted. Remove and install again using the SDK Managerとあったので、
https://qiita.com/EGJ-Takashi_Suzuki/items/d7fc3930a397b848adf6　に従い、自分のandeoid10に合うように再インストールしましたが、まだ、同じエラーがでます。

また、Androidstudio側でも下記のエラーが出てお手上げの状態です。
Task 'wrapper' not found in project ':launcher'.

• Try:

Run gradle tasks to get a list of available tasks. Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.

Unity よく分かりませんが、

Target API と Build Tool のバージョンがあってない可能性。
https://www.reddit.com/r/Unity2D/comments/ozlltt/unity_2021_gradle/

Gradle plugin が古い？
https://stackoverflow.com/questions/66992420/when-i-try-to-sync-project-with-gradle-files-a-warning-pops-up

または、Build tools と Target SDK を 30 に下げるとか…。

下記のサイトの手順で解決ができました。
https://stackoverflow.com/questions/68387270/android-studio-error-installed-build-tools-revision-31-0-0-is-corrupted

\\\\\\\\\\\\\\\\\\\\
First of all, I faced this issue in Android Studio 4.2.2 and you do not need to downgrade the SDK build tool from 31 to 30 or change compile SDK version.

The main problem is the two files missing in SDK build tool 31 that are:

dx.bat
dx.jar
The solution is that these files are named d8 in the file location so changing their name to dx will solve the error.

The steps are below.

For Windows
go to the location

"C:\Users\user\AppData\Local\Android\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:\Users\user\AppData\Local\Android\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.
