How to Fix Flutter Doctor –android-licenses : Exception in thread “main” java.lang.NoClassDefFoundError

Flutter Error – Flutter Doctor –android-licenses : Exception in thread “main” java.lang.NoClassDefFoundError

Sometimes flutter won’t accept the android license. It will get the following error:

C:\Users\Chamara>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)

This is what flutter doctor returns:

We have two methods to solve this problem.

Method 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’.

Method 2

May be you still not have Java install on your computer. So install java from https://www.oracle.com/java/technologies/javase/javase-jdk8-downloads.html

After check for your JAVA_HOME path under System Variables it should be like:

C:\Program Files\Java\jre1.8.0_291
(no semi-colon and no \bin)

restart terminal and try again with:

 flutter doctor --android-licenses
