Flutter Doctor --android-licenses : Exception in thread "main" java.lang.NoClassDefFoundError

Question

I'm trying to install flutter but it won't let me accept the android license. I get the following error:

PS C:\Users\XXXX> flutter doctor --android-licenses
Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema
        at com.android.repository.api.SchemaModule$SchemaModuleVersion.<init>(SchemaModule.java:156)

        at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:522)
        ... 5 more

I've already uninstalled my current version of Java and clean installed Java 8 from here.

This is what flutter doctor returns:

[✓] Flutter (Channel stable, 1.22.3, on Microsoft Windows [Version 10.0.18363.1139], locale en-IE)
[!] Android toolchain - develop for Android devices (Android SDK version 30.0.2)
    ✗ Android license status unknown.
      Run `flutter doctor --android-licenses` to accept the SDK licenses.
      See https://flutter.dev/docs/get-started/install/windows#android-setup for more details.

Solution 1

Installing Android SDK Command-line tools from Android SDK Manager did the job for me.

1. Open Android Studio
2. Tools > SDK Manager
3. From the left choose, Appearance & Behavior > System Settings > Android SDK
4. Select SDK Tools from the top menu
5. Check Android SDK Command-line tools and click 'apply'.

Solution 2

Firstly check for your JAVA_HOME path under System Variables it should be like -->

C:\Program Files\Java\jdk-15.0.2
(no semi-colon and no \bin)

and add to path (in System Variables)--> %JAVA_HOME%\bin

if still, you are getting any error try this in Android Studio--> Setting(Appearance & Behavior) -> Android SDK -> check and download Android SDK Command-line tools.

restart terminal and try again with flutter doctor --android-licenses

--> this should do the work.

This is not true. The issue is caused by the CL-toole missing as the accepted answer suggests. Android Studio does not install them by default as it seems.

Thanks, it did solve the issue! I wonder how people find the solution like this?))

For cmdline-tools without Android Studio, call sdkmanager "cmdline-tools;latest" in command line instead.
