I am installing Flutter on my Intel Mac.

I installed Java for Mac from this link on January 2023 from Here

Has someone encountered the same error? How did you fix it?

    2. Pick Java 19 and the x64 DMG Installer (this worked for me)
    3. Follow the installation instructions.
    4. [optional] If necessary, set your JAVA_HOME path following these instructions (mac)
    5. Test the installation by running flutter doctor --android-licenses

    Additionally from what Tomas Ward said about installing the lastest SDK, for windows I found this for adding the JAVA_HOME to the path. Hope it helps.

    While installing the JDK by Oracle download works, best way to make sure that you have the correct version on MacOS is to install JDK using Homebrew (If you don’t have Homebrew, Installation instructions: https://docs.brew.sh/Installation). Also, keeping it up-to-date is a lot easier this way.

    brew install openjdk

    If you have other OpenJDK versions installed, you may need to link this correct one:

    brew link --force openjdk@19

    To make it the default for your shell, add the following lines to ~/.zshrc:

    export JAVA_HOME="/opt/homebrew/opt/openjdk"
export PATH="$JAVA_HOME/bin:$PATH"

    And then:

    source ~/.zshrc

    You only need to do this once.

    Then rerun: flutter doctor --android-licenses

    I tested a higher version (jdk17) and successfully executed it. But I don’t think this is a good idea. Let’s wait for the official solution

    None of these answers worked for me. So I finally bit the bullet and switched over to asdf. It’s worth it and will save you so much trouble in the future.

    1. asdf install java adoptopenjdk-19.0.0+36
    2. asdf global java adoptopenjdk-19.0.0+36
    3. Do what this comment suggests and add this to your .zshrc 
      # set JAVA_HOME on every change directory
function asdf_update_java_home {
  asdf current java 2>&1 > /dev/null
  if [[ "$?" -eq 0 ]]
  then
      export JAVA_HOME=$(asdf where java)
  fi
}

precmd() { asdf_update_java_home; }
# end set JAVA_HOME
    4. exec zsh # reloads current terminal to use changed .zshrc
    5. echo $JAVA_HOME should show asdf directory one
    6. flutter doctor --android-licenses

    • Macbook Pro M1
    • ZSH as my shell
