Why my Flutter app don't run? BUG! exception in phase 'semantic analysis' in source unit '_BuildScript_' Unsupported class file major version 60

I tried to figure it out, but I couldn't even find how. Please help me.

When I try to run my first flutter app this happen:

FAILURE: Build failed with an exception.

* What went wrong:
Could not open settings generic class cache for settings file 'C:\Users\Angel\Downloads\Codigo\Flutter\first_app\android\settings.gradle' (C:\Users\Angel\.gradle\caches\6.7\scripts\1fnwrr8g4rohfp291nvlxj5qe).
> BUG! exception in phase 'semantic analysis' in source unit '_BuildScript_' Unsupported class file major version 60

* Try:
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.

* Get more help at https://help.gradle.org

BUILD FAILED in 2s

Running Gradle task 'assembleDebug'... Done                         3.5s
Exception: Gradle task assembleDebug failed with exit code 1

I already tried with a physical device and the emulator. I try with "flutter clean". flutter doctor -v say all is good.

If it's helpful here is what comes out when running 'flutter run -v':

Current JDK version : 17

In project/android/gradle/wrapper/gradle-wrapper.properties, set this

distributionUrl=https\://services.gradle.org/distributions/gradle-8.3-all.zip

There are many answers here which tell you to check compatibility matrix but in this context I think instead of checking with java - gradle compatibility, you need to check for Android - Gradle compatibility.

on Java 17, my 7.3 Gradle was not supported and error was shown by Android studio. I scrolled down to bottom of https://docs.gradle.org/current/userguide/compatibility.html#Android to check for Android - gradle

Hence, picked 8.3 gradle version.

I have fixed the issue by steps below,

  1. Check Gradle version by running command - flutter doctor --verbose. In my case it was - Java version OpenJDK Runtime Environment (build 21.0.3+-79915915-b509.11)
  2. Update Gradle Wrapper: Updated my gradle-wrapper.properties file located in the android/gradle/wrapper directory. Refer the Gradle compatibility documentation - https://docs.gradle.org/current/userguide/compatibility.html. In my case it was 8.5
  3. Set Correct Distribution URL: I updated the distributionUrl in the gradle-wrapper.properties file to the following: distributionUrl=https://services.gradle.org/distributions/gradle-8.5-all.zip

I have changed the gradle version of java, its work for me.

  1. first check the gardle java version => through commond : java -version or => Go to C drive -> program files -> java (where you see the jdk file and version)

  2. Second check 'Edit and System Enviroment' => check the path and also check the JAVA HOME path

  3. Third Go to your project Android -> app -> gradle/wrapper -> gradle-warpper.properties change the gradle version

    distributionUrl=https://services.gradle.org/distributions/gradle-8.5-all.zip

check with this link https://docs.gradle.org/current/userguide/compatibility.html

I resolved this issue by downgrading my JDK version 19 to JDK 17. Also, change the paths of both - User Variables and System Variables.

And Don't forget to configure the Project Structure of the Flutter Project after JDK Downgrade. Screenshot for Reference

I just update distributionUrl value at android\gradle\wrapper\gradle-wrapper.properties to a gradle compatible with my JDK version (19)

distributionBase=GRADLE_USER_HOME
distributionPath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-7.6-bin.zip
zipStoreBase=GRADLE_USER_HOME
zipStorePath=wrapper/dists

So, I use gradle 7.6 following the Compatibility Matrix from Gradle docs (https://docs.gradle.org/8.0/userguide/compatibility.html)

Yes, downgrading the jdk version solves the problem. In may case this problem was experienced both in android studio android project and in IntelJ in spring boot project.
