Unable to find bundled java version flutter windows

Right approach

In short and simple, the best approach to fix this issue is by upgrading your Android Studio and Flutter to latest versions, in order to avoid any potential issues (e.g. patching) in future.

Original answer

For those having these issues with the latest Android Studio — Electric Eel version, and other canaries and preview releases, note that the bundled jre directory in the Android Studio installation folder is now renamed to jbr

To resolve this, just create a sym link jre -> jbr and Flutter won’t complain.

On Linux

cd ~/android-studio/ && ln -s jbr jre

Windows (check installation folder)

cd C:\Program Files\Android\Android Studio
mklink /D "jre" "jbr"

New-Item -ItemType SymbolicLink -Path .\jre -Target .\jbr

Mac OS

cd /Applications/Android\ Studio.app/Contents
ln -s jbr jre

Note that if you are running a preview release, and depending on your OS, the default installation directory might be different, e.g. on Linux it would be

~/android-studio-preview/

In either case, you can check the installation directory by running

flutter doctor -v

Also, in case if you run with permissions issues, you can try running the command with admin privileges, depending on your OS.

For example on Mac/Linux, you can just run the same command with sudo and it should work, additionally on Mac, you’ll have to configure the Disk Access permissions, depends on your version, but most probably can be found under:

Settings - Privacy & Security - Full Disk Access - Terminal

Problem:

Cause: If you run “flutter doctor” on your terminal and you see something similar to the screenshot below, Java cannot be found on your system and is the cause of this error.

1. To fix this kind of Error you must check first the java and jdk version. If you have already installed java in your pc or laptop. Run this command java -version and echo %JAVA_HOME% on command prompt.

Command: echo %JAVA_HOME%

If the version shows in the command for java and jdk in your pc or laptop is the same proceed to the step 2.

2. Check the System Environment Variables

To Access the Environment Variables, use search bar on the windows and search System Environment Variable

Click the Edit System Environment Variables after that click the button Environment Variables..

Click JAVA_HOME Enviroment Variable on system environment.

Check if the jdk version on your pc or laptop is the same on the JAVA_HOME Environment Variables. Now if it is still the same click the Path on the System Variables.

How about if you have not already set the Environment Variable JAVA_HOME in your pc or laptop. You can learn how to set up this environment variables on https://confluence.atlassian.com/doc/setting-the-java_home-variable-in-windows-8895.html

Even the system JAVA_HOME Environment Variable of your is the same with the jdk version on your system and still not detected you must try the step 3.

3. Goes to Local Disk C and browse the Program Files and follow this following steps:

First, right-click the Android Studio icon and open the file directory(location). Your installation folder should be at “C:\Program Files\Android\Android Studio”.
When you are already at the Android Studio installation root folder, you will see two folders: “jbr” and “jre“.
Copy all the files inside the “jbr” folder to the “jre” folder, then try it again.

Paste the files from jbr in jre

Run again the flutter doctor command

Could you provide help please ?

Solution

So here the action I have done:
Install latest version of jdk: https://www.oracle.com/java/technologies/javase-downloads.html

Install latest version of jre: https://www.oracle.com/java/technologies/javase-jre8-downloads.html

Go to: C:\Program Files\Android and remove all version of Android Studio

Go to Windows search: Environement Variables > Environement Variables > System Variables and add JAVA_HOME with value the path to your jdk (C:\Program Files\Java\jdk-16.0.2)

Install Android Studio again

Go to file > Project Structure

Put your JDK path:

Go to file > Settings

Click on Show Package Details and retrograde to 20.1 or 22.2 (not sur for 22.2 but read that for some it works)

Verify you’re on a stable version:

flutter pub get
flutter pub upgrade
flutter pub outdated
flutter doctor -v

and it should be good: • Java version OpenJDK Runtime Environment (build 11.0.10+0-b96-7249189)

Introduction

Flutter is a popular framework for developing cross-platform mobile applications. It provides a rich set of features and libraries that simplify the app development process. However, when working with Flutter, it’s essential to understand and manage the bundled Java version. This guide will help you troubleshoot and locate the bundled Java version in your Flutter environment.

What is a Bundled Java Version in Flutter?

Before diving into troubleshooting, let’s understand what a bundled Java version means in the context of Flutter. When you install Flutter, it includes a pre-packaged Java Development Kit (JDK) that is required for Android app development. This bundled JDK ensures that Flutter apps can be compiled and run on Android devices seamlessly.

Why is it Important to Find the Bundled Java Version?

Finding the bundled Java version is crucial for various reasons. Firstly, knowing the specific JDK version used by Flutter helps ensure compatibility with the Android platform and related libraries. Secondly, troubleshooting certain issues in Flutter projects often requires knowledge of the underlying JDK version. Therefore, locating the bundled Java version is a fundamental step for maintaining a stable and productive development environment.

Troubleshooting: Unable to Locate the Bundled Java Version

If you’re unable to find the bundled Java version in your Flutter setup, don’t worry. Follow these troubleshooting steps to identify the Java version:

a) Checking the Flutter SDK Installation

Ensure that you have the latest Flutter SDK installed on your system.
Open a terminal or command prompt and run the following command:

This command provides information about your Flutter installation, including the bundled Java version.

b) Verifying the System Path Environment Variable

Check if the system Path environment variable is properly configured to include the Flutter SDK location.
Open a terminal or command prompt and run the following command:

Ensure that the Flutter SDK path is included in the output.

c) Inspecting Flutter Project Configuration

Open your Flutter project in a code editor.
Look for the android folder and navigate to the app directory.
Inside the app directory, locate the build.gradle file.
Open the build.gradle file and search for the compileOptions section.
Within compileOptions, you’ll find the sourceCompatibility and targetCompatibility settings. These indicate the Java version used by the project.

d) Exploring Platform-Specific Requirements

Flutter projects often have platform-specific requirements, such as additional Java dependencies or configuration files.
Consult the official Flutter documentation or relevant resources specific to your project’s target platform (e.g., Android) for any specific instructions on locating the bundled Java version.

Alternative Methods to Identify the Bundled Java Version

If the troubleshooting steps mentioned above do not yield the desired results, you can try alternative methods to identify the bundled Java version in Flutter:

a) Using Flutter Doctor Command

Open a terminal or command prompt.
Run the following command:

This command provides detailed information about your Flutter installation, including the bundled Java version.

b) Checking the Flutter SDK Release Notes

Visit the Flutter SDK release notes on the official Flutter website.
Look for the release notes related to your installed version of Flutter.
Check if any specific information regarding the bundled Java version is mentioned.

c) Reviewing the Flutter Project Files

Go through the project files in your Flutter project, such as pubspec.yaml, android/gradle.properties, or any other relevant files.
Look for any references to the Java version or related configuration that might indicate the bundled Java version.

Best Practices for Managing Flutter’s Bundled Java Version

To ensure a smooth development experience with Flutter, consider the following best practices for managing the bundled Java version:

a) Keeping the Flutter SDK Updated

Regularly update your Flutter SDK to the latest stable version. This ensures that you have access to the most recent improvements, bug fixes, and bundled Java version updates.
