Fix Flutter doctor failed due to java.lang.NoClassDefFoundError

Trouble

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.

Solution

I solved it via Android Studio settings with installation of โ€œAndroid SDK Command-line Toolsโ€

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.

Confirmation

Finished when Finsh button is activated.

Acknowledgment

Many thanks to Github Flutter issues (51670 / 56778) and ใถใ‚‹ใƒผ's zenn.dev post.

Result

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

Successful

Then flutter doctor, too ๐Ÿ™‚

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.ย  - dev.to/pablonax/free-vs-paid-flutt...
