Android Studio – BUG! exception in phase 'semantic analysis' in source unit '_BuildScript_' Unsupported class file major version 61 on Apple Arm

I have installed Android Studio Canary 2020.3.1.22 and trying to run Flutter project on Apple Silicon(ARM) Mac. Unfortunately, it is giving me this error when I try to run default flutter counter app.

Here is the error I am getting:

Gradle version: 6.7 but I tried 7+
JDK version 17

I would really appreciate your help)

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

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

    When done, everything worked smoothly.

    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

    Preferences -> Build -> Build Tools -> Gradle -> Gradle JDK

    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
    14.0.1 (x86_64) "Oracle Corporation" - "OpenJDK 14.0.1" /Users/ciccio/Library/Java/JavaVirtualMachines/openjdk-14.0.1/Contents/Home
    11.0.12.1 (x86_64) "Amazon.com Inc." - "Amazon Corretto 11" /Users/ciccio/Library/Java/JavaVirtualMachines/corretto-11.0.12/Contents/Home
    10.0.2 (x86_64) "Oracle Corporation" - "Java SE 10.0.2" /Library/Java/JavaVirtualMachines/jdk-10.0.2.jdk/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.

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

    1. If you are developing a Flutter project and got this error, go to File -> Close Project.
    2. Then re-open from the android folder (omit this if you received from a pure Android project).
    3. 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.
    4. 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).
    5. 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.

    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.

    I had this issue when I set the target for a new IntelliJ Kotlin project to be Java 17. My fix was to:

    • set the target to 9 in build.gradle.kt
    • close the project
    • delete the .gradle and .idea directories from the project folder
    • remove the project from the recent projects list
    • open the gradle file from IntelliJ and get it to rebuild everything

    Open the Gradle settings and change the Gradle JVM to the same JDK version you are using.
    (I am using 14.0.2)
    This worked for me.

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

    Here is a configuration that works:

    System:
    Mac with ARM, Mac OS 12.1, M1 Max

    • java version 18.0.1-zulu
    • kotlin version 1.7.0
    • gradle version 7.5

    I installed those version with sdkman https://sdkman.io/
    and set the config manually on intellij (See attached Screenshot for Details)

    My solution was to open the android project in Android Studio. It detected the needed Gradle update and performed the update upon command.

    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

    source ~/.bash_profile

    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.

    On my side I fixed this issue by setting the default Java Version to 8 (download it if needed)

    Mac:

    1. Open Terminal.
    2. open ~/.bash_profile
    3. Add
    # SWITCH TO JAVA VERSION 8
export JAVA_HOME=`/usr/libexec/java_home -v 1.8`
    1. Save and restart Android Studio.

    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:

    1. Command in the terminal:

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

    2. Check classpath, current working one:

      classpath ‘com.android.tools.build:gradle:7.1.2’

    3. 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

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

    enter image description here

    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.

    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

    Context: Flutter, Mac M1, Java 19.0.2

    Problem occured on following command:

    flutter build apk

    I just installed (reintalled) gradle via homebrew like this:

    brew install gradle

    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.

    Please, verify it with following commands:

    java -version
gradle -version

    I think this process / solution can be applicable in general. Hope it helps!

    System: Mac M1, Android Studio Electric Eel (2022.1.1 Patch 1), JDK 19.02

    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:

    1. Open the flutter project in Android Studio
    2. Open build.gradle, the one under android folder
    3. 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.
    4. 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.
    5. Done! Close the build.gradle and re-run the project. It should build and run fine.

    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

    Usually, this bug relates to the incompatibility of the gradle version and the JDK version.

    if you want to be sure. first check this for compatibility.

    if this is your problem. find your version in this, then rename your version in gradle-wrapper.properties of your project.

    In my case I had this set

    Typing flutter --version on terminal:

    Flutter 3.7.5 • channel stable • https://github.com/flutter/flutter.git
Framework • revision c07f788888 (10 weeks ago) • 2023-02-22 17:52:33 -0600
Engine • revision 0f359063c4
Tools • Dart 2.19.2 • DevTools 2.20.1

    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
