How to fix ERROR: JAVA_HOME is set to an invalid directory (Flutter android licenses)

Question

This whole issue occurred when i ran flutter doctor in cmd.Flutter doctor showed issue as:

Android toolchain - develop for Android devices (Android SDK Version 30.0.3) 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.

So, I ran flutter doctor --android-licenses then it showed output as:

ERROR: JAVA_HOME is set to an invalid directory: C:\Program Files\Java\jdk-16.0.1\bin

Please set the JAVA_HOME variable in your environment to match the location of your Java installation.

I have tried many methods like: change the directory to C:\Program Files\Java\jdk-16.0.1 (no bin) but then when i run flutter doctor --android-licenses it shows

Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema at com.android.repository.api.SchemaModule$SchemaModuleVersion.(SchemaModule.java:156) at com.android.repository.api.SchemaModule.(SchemaModule.java:75) at com.android.sdklib.repository.AndroidSdkHandler.(AndroidSdkHandler.java:81) at com.android.sdklib.tool.sdkmanager.SdkManagerCli.main(SdkManagerCli.java:73) at com.android.sdklib.tool.sdkmanager.SdkManagerCli.main(SdkManagerCli.java:48) Caused by: java.lang.ClassNotFoundException: javax.xml.bind.annotation.XmlSchema at java.base/jdk.internal.loader.BuiltinClassLoader.loadClass(BuiltinClassLoader.java:636) at java.base/jdk.internal.loader.ClassLoaders$AppClassLoader.loadClass(ClassLoaders.java:182) at java.base/java.lang.ClassLoader.loadClass(ClassLoader.java:519) ... 5 more

Please help me solve this issue, Thank You!

Solution 1

First of all you need to install "Android SDK Command Line Tool" in andriod studio. Settings > System Settings > Android SDK > SDK Tool --> Android SDK Command Line Tool (as shown in the following screenshot)

Then watch this video -> https://www.youtube.com/watch?v=104dNWmM6Rs&ab_channel=CodeJava

Solution 2

I ran same issue like this and spend couple of hour on it and finally solved it. I am sharing my solution as someone might get beneficial.

First Issue : When i ran flutter doctor --android-licenses, i got below error.

Exception in thread "main" java.lang.NoClassDefFoundError: javax/xml/bind/annotation/XmlSchema

Second Issue : Then i thought it would be lack of jdk so i install jdk 8 , setup JAVA_HOME environment variable and ran flutter doctor --android-licenses , i got another error shown below.

ERROR: JAVA_HOME is set to an invalid directory: C:\Program Files\Java\jdk-jdk1.8.0_29

Please set the JAVA_HOME variable in your environment to match the location of your Java installation.

Solution : I installed Android SDK command line tool as shown in screenshot above in Android Studio and removed JAVA_HOME environment variable. Then i restart my laptop and it works. This issue has been discussed on flutter official github so here is the link https://github.com/flutter/flutter/issues/84325. I thank to TahaTesser and Pasindu Dilanka.

Conclusion :

There is no need to setup external jdk, as

default JDK that comes with Android Studio itself, which is java 11.

Try to reinstall JAVA.

Reinstalling Java is not a solution. Fixing JAVA_HOME is the solution.
