According to the official grade docs: Java 17 and later versions are not yet supported.

You can check compatibility here.

So I have installed Java11 from Azul.

p.s. don't forget to change jdk version in Android studio

Got the same error while I upgraded my build.gradle to Java 17. And the fix is as simple as we think:

Gradle starts supporting Java17 only from 7.3 release

Here's the complete reference for Java vs Gradle compatibility: https://docs.gradle.org/current/userguide/compatibility.html

Upgraded my gradle to 7.3 in gradle-wrapper.properties.

https\://services.gradle.org/distributions/gradle-7.3.3-bin.zip

Some of you may experience now the Gradle dependency cache corrupt error after this like me. So better delete the gradle-wrapper.jar and reinstall it using the command:

./gradlew wrapper

Everything will work perfectly fine from here.

In case if you still face Gradle corrupt issue, please check whether you are using latest version of IDE especially Intellij.

First, you can execute this command: /usr/libexec/java_home -V, to retrieve all installed jdsk:

[~]$ /usr/libexec/java_home -V

Matching Java Virtual Machines (4):
    17.0 (x86_64) "Oracle Corporation" - "OpenJDK 17.0" /Users/ciccio/Library/Java/JavaVirtualMachines/openjdk-17.0/Contents/Home

    1.8.0_302 (x86_64) "Amazon" - "Amazon Corretto 8" /Users/ciccio/Library/Java/JavaVirtualMachines/corretto-1.8.0_302/Contents/Home

Now, imagine you want to remove the version 17:

[~]$ java -version
openjdk version "17" 2021-09-14
OpenJDK Runtime Environment Homebrew (build 17+0)
OpenJDK 64-Bit Server VM Homebrew (build 17+0, mixed mode, sharing)

Go into the path of the version you want to remove (in this case "/Users/ciccio/Library/Java/JavaVirtualMachines/openjdk-17.0/Contents/Home"), and delete entire folder: "/Users/ciccio/Library/Java/JavaVirtualMachines/openjdk-17.0".

Once removed, go back on terminal and use:

[~]$ /usr/libexec/java_home -v 14.0.1 --exec javac -version
javac 14.0.1

to force the new version to use (14.0.1).

Next check if is correct:

[~]$ java -version
openjdk version "14.0.1" 2020-04-14
OpenJDK Runtime Environment (build 14.0.1+7)
OpenJDK 64-Bit Server VM (build 14.0.1+7, mixed mode, sharing)
[~]$

Your Gradle now is back to work.

Happened with newly created Flutter app in 2023 January with Mac Mini M1. If you have another working Flutter apps do not downgrade or update Java version as it will cause problem with all other working ones. Find gradle-wrapper.properities file inside gradle/wrapper folder (directly inside Android folder) and check gradle version. You just need to use newer version of gradle. I replaced this one and used flutter run command from terminal and it worked:

distributionUrl=https\://services.gradle.org/distributions/gradle-7.5-all.zip

With this one:

distributionUrl=https\://services.gradle.org/distributions/gradle-7.6-all.zip

No need to do anything else. Version number may be different for you depending on when you are trying this and what Java version you have.

Note: Same fix also effective for another error message as well stating version 63:

BUG! exception in phase 'semantic analysis' in source unit '_BuildScript_' Unsupported class file major version 63

Basically, I installed jdk using brew install java which was not compatible with my current gradle I guess. So

I uninstalled java first using: brew uninstall java
installed JDK 8 or JDK 11 from azul.
Installed gradle: gradle-6.9-all.zip

When done, everything worked smoothly.

I found a way to fix this error without messing with the locally installed Java version or Gradle. Here is what I did:

If you are developing a Flutter project and got this error, go to File -> Close Project.
Then re-open from the android folder (omit this if you received from a pure Android project).
Now, Gradle may detect the issue on its own, and it will take a while to check. After it is done, it may provide upgrade steps in an upgrade assistant window at the bottom of the window along with logcat, build, terminal etc… which you need to accept and tell it to execute. Once it finishes, the error is resolved, and you are good to go.
If it does not seem to do anything on its own, then please open the Project Structure tab. Now select the latest Gradle version available that does not contain -rc (you don't want these, most of the time they are not stable releases).
Now select the JDK version that Gradle uses by going to Gradle (sidebar on the right of the window) -> Wrench Icon -> Gradle Settings. Select a compatible JDK version according to the Gradle project's documentation, as found HERE. Current latest stable version of Gradle is 7.4 with maximum supported JDK version 17 (also latest I believe if you use something like openJDK which I use), but Android Studio version at 7.1 so be careful.

Tested on MacBook Air M1 running macOS Monterey 12.2.1.

Finally I Got the Solution

It is very easy to solve

step 1 : select the gradle version which support your java version link

step 2 : open your project navigate to your_project_name/android/gradle/wrapper/gradle-wrapper.properties

step 3 : in distributionUrl change the gradle version according to your java version

That's it No need to install older java versions

Happy coding

Check currently active java version:-

javac -version

If it is greater than 11 downgrade it to 11 or 8. Check your available java jdk version installed:-

/usr/libexec/java_home -V

If java 11 or 8 is not installed first install one of them using this link:- Download jdk 8

then change the default java version in .bash_profile

Edit .bash_profile

sudo nano ~/.bash_profile

Add 1.8 or 11 as default. (Add below line to bash_profile file)

export JAVA_HOME=$(/usr/libexec/java_home -v 1.8)

OR

export JAVA_HOME=$(/usr/libexec/java_home -v 11)

Now Press CTRL+X to exit the bash. Press 'Y' to save changes. And reload bash_profile

In my case I had this set

Typing flutter --version on terminal:

Flutter 3.7.5 • channel stable • https://github.com/flutter/flutter.git

Typing javac -version on terminal to get you java version:

javac 19.0.2

So, by this grade compatibility matrix I had to update my project/android/gradle/wrapper/gradle-wrapper.properties distributionUrl to:

distributionUrl=https\://services.gradle.org/distributions/gradle-7.6-all.zip

And if necessary, after this, close the IDE (in my case VS Code) and reopen it. The error is gone. That worked for me. Thanks! — Mobterest Studio, Jul 27 '23 at 12:42

I encountered this error when created a fresh project using flutter create and tried to run it in Android Studio.

Now I've got an interesting solution that worked for me:

Open the flutter project in Android Studio
Open build.gradle, the one under android folder
On the top right it shows "Open for Editing in Android Studio" (although it's already in Android Studio!). Click on that to open it for editing. I opened it in another window, but doesn't matter.
It starts to automatically download and update gradle to sync the build file. At one point, tt might also prompt you to upgrade gradle, which is good to do.
Done! Close the build.gradle and re-run the project. It should build and run fine.

I was trying to clone a Flutter project from GitHub that was working perfectly until the last commit and push. After deleting it locally and cloning it again, I encountered an error when opening it in Android Studio.

Solution:

Open the Android module of the Flutter project in Android Studio.

Set the Gradle JDK to zulu-17 by going to Settings > Build, Execution, Deployment > Gradle. In my case, the Gradle Plugin Version was 7.2.01, which can be found in File > Project Structure > Project. Check the Gradle documentation to find the compatible JDK versions for your Gradle version. https://docs.gradle.org/current/userguide/compatibility.html

Run java -version in the Flutter project's terminal window. In my case, it showed a different Java version than zulu-17.

Set the JDK path in the .zshrc file located at /Users/homepathname/.zshrc:

export JAVA_HOME="/Users/homepathname/Library/Java/JavaVirtualMachines/azul-17.0.7/Contents/Home"
export PATH=$JAVA_HOME/bin:$PATH

Open a new terminal window in the Flutter project and run java -version again. This should show the same Java version as the Gradle JDK.

The project should now run without any problems.

This solution worked for me as it synchronized the Java versions used by Gradle and the terminal.

I had that Issue creating Projects from IntelliJ. It seems the issue was the Gradle JVM Version.

Here is a configuration that works:

I can't speak for everyone, but for me, I went into Flutter project's file android/gradle/gradle.properties, and changed the org.gradle.java.home value so that it pointed to a folder containing JDK 11 instead of JDK 18. That way, it used a JDK version that was actually supported.

Giving my two seconds here... In my case, I could fix it by finding my gradle version in the file gradle.wrapper.properties and checking the compatibility with the JDK, so I needed to install the JDK 16, so in my build.gradle(:app) I put this line of code inside the android {} :

compileOptions {
   sourceCompatibility JavaVersion.VERSION_16
   targetCompatibility JavaVersion.VERSION_16
}

After this I build my android version again, and it worked.

I ran into this issue on VSCode+Mac using the Gradle for Java extension.

My project uses Java 17 but Gradle was using JDK19, which I also had installed. I removed the jdk-19.jdk folder from /Library/Java/JavaVirtualMachines and then ran the "Clean Java Language Server Workspace" task in VSCode.

After that, Gradle successfully built and I was even able to put the jdk-19 folder back and things continued to work.

Easy fix in 2023:

Command in the terminal:

export JAVA_HOME=$(/usr/libexec/java_home -v 1.8)
Check classpath, current working one:

classpath 'com.android.tools.build:gradle:7.1.2'

Check gradle-wrapper.properities file:

 distributionBase=GRADLE_USER_HOME
 distributionPath=wrapper/dists
 zipStoreBase=GRADLE_USER_HOME
 zipStorePath=wrapper/dists
distributionUrl=https\://services.gradle.org/distributions/gradle-7.4-all.zip

If still not solved you need to change Gradle JDK from inside Android Studio like below.

After that you can run fluter app directly from terminal without any issue. Note: Android Studio default JDK (11.0.15) does not work and causes this issue. Azul Zulu 16.0.2 works and solves the issue.

I suppose it was related to my recent upgrade (Java was upgraded to OpenJDK Temurin 19.0.2).

I also noticed that flutter command was trying to use gradle 7.4 (the only one gradle version installed before). As previously mentioned by others, there has to be consistency between your Java version and gradle version according to Gradle Official Compatibility Matrix.
