Fix Flutter doctor failed due to java.lang.NoClassDefFoundError


I updated Flutter version to 2.2.0 on my Arch Linux today.
Then I met the error "Android license status unknown." in running flutter doctor for the first time. It seemed strange because I had already run it with an option: flutter doctor --android-licenses. Anyway, there was no way except running it again. And the result was:

Console error

Thus, I got "java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema". Puzzled.


I solved it via Android Studio settings with installation of “Android SDK Command-line Tools”

Start Android Studio.
Go to [ File ] -> [ Settings ] in main menus.

Android Studio main menus

In Settings, go to [ Appearance & Behavior ] -> [ System Settings ] -> [ Android SDK ].
Activate "SDK tools" tab.
Check "Android SDK Command-line Tools". Click "OK".

Android Studio Settings

Go on.

Android Studio Android SDK

The command-line tools will be installed.


Finished when Finsh button is activated.


Many thanks to Github Flutter issues (51670 / 56778) and ぶるー's post.


flutter doctor --android-licenses printed the process had been successful.


Then flutter doctor, too 🙂

flutter doctor completed

If you are interested in this topic, you can also look at my article about free vs paid Flutter templates. I'm sure you'll find something useful there, too.  -
