Unable to find bundled Java version on Flutter
Here's the helping hand to your “Unable to find bundled Java version” error in Flutter. Start your rescue mission by confirming you have the Java Development Kit (JDK) installed. Update your JAVA_HOME environment variable with the correct path. Let's do a quick health check:
- On Windows:
echo %JAVA_HOME%andjava -version. - On macOS/Linux:
echo $JAVA_HOMEandjava -version.
If the doctor's report (JAVA_HOME) comes back negative, scribble this in your shell notepad (~/.bashrc or ~/.zshrc):
export JAVA_HOME=$(dirname $(dirname $(readlink -f $(which javac))))
Re-energize your terminal with source ~/.bashrc (or zshrc), etc., and summon flutter doctor again. In case things got worse, it's high time to re-check your Flutter SDK installation.
Mac users, if you're still scratching your heads after an update, try creating a symbolic link to the bundled Java runtime. Follow these breadcrumb trails in the Terminal:
- Be an adventurer and navigate to the mysterious Android Studio package contents:
cd /Applications/Android\ Studio.app/Contents - Craft a magical symbolic link named "jre" that points to the powerful JetBrainsRuntime directory using this ancient spell:
ln -s jbr jre
If the winds are still against you, consider levelling up both Android Studio and Flutter to their latest versions to dance to the rhythm of the bundled Java.
On the Windows side of things, if the path to the bundled Java vanished after an update, you can dust off your Sherlock's cap and try renaming the "jre" directory to "jbr" or vice versa in your Android Studio's treasure chest.

Flutter Quest (💎) needs Java Key (🔑) to open the Treasure Chest (📦).
Disheartened, you search your inventory (💼)...
🔍 Inventory (💼) search... Alert: Java Key (🔑) is missing!
Don't get disheartened yet, brave adventurer! Grab your toolkit and prepare to do the following:
- Consult the Flutter Doctor (🩺)
- Reforge or Upgrade your Java Key (🔑)
- Validate your Environment Rune (🗿)
Deploy this new toolkit strategy. Be prepared to battle through code, commands, and config files. The quest must go on!
Rechecking the Java environment setup
Straightening up JAVA_HOME path
Make sure that the JAVA_HOME path leads the way not to JRE, but to the mighty JDK, the weapon you need to conquer Flutter. Mac adventurers may also consider using homebrew, the trusted map, to navigate through the installations and dependencies.
Playing nice with mac permissions and symbolic links
Since the coming of macOS Mojave, adventurers might need to negotiate Disk Access permissions for our sidekick, Android Studio. Seal the deal by giving Terminal Full Disk Access for the symbolic links to be crafted without disturbances.
Cleaning up old installations
Having multiple sidekicks (Android Studio versions) can lead to quarrels about which Java version is the true hero. Remove any older versions to ensure only the true hero is recognized.
Flutter Doctor's Post-check up
After performing the magic spells and maneuvers, summon flutter doctor -v to assess your deeds and ensure Flutter acknowledges the Java environment correctly. If the diagnosis is positive, feel free to do a victory dance 🕺.
