I reinstalled my android studio since the sdk was not found and so on. After re installing java jdk and android studio , everything worked well until I got an error saying 'Could not initialize class org.codehaus.groovy.runtime.InvokerHelper' which I solved by changing the Gradle version. And now the error is 'Type 'FlutterTask' property 'assets' is missing an input or output annotation.'

FAILURE: Build failed with an exception.

  • What went wrong: Could not open settings generic class cache for settings file 'C:\Users\loran\ASProjects\xylophone-flutter\android\settings.gradle' (C:\Users\loran.gradle\caches\6.8.2\scripts\4mawlyb2l5e9tefyvnpxva1kg).

Java JDK 16 is the one that seems to lead to this issue try downgrading by downloading a lower version of JDK preferable JDK 8 or 11

To future individuals who will run to this error. Here is the link to download the JDK enjoy your coding experience don't forget to change the path too. https://www.oracle.com/java/technologies/javase-downloads.html

Try installing the latest Gradle package gradle-7.1.1, if you are using Java JDK 16 installed. To do this open android/gradle/wrapper/gradle-wrapper.properties file and under distribution url, update the gradle version to 7.1.1 (or the latest). After that, inside your Flutter project directory, run the following command in the terminal:

cd android && ./gradlew

If this error occurs, this might because you have installed the latest JDK such as JDK 16. You download and install JDK 8 and uninstall JDK 16. Then restart the desktop/laptop and try launch and run flutter run again. It should be working fine.

I removed the JAVA_HOME path to the JAVA download and changed JAVA_HOME path to the following:

C:\Program Files\Android\Android Studio\jre

I am now coding

Try this! Remove package android from the top of settings.gradle. This helped me out.

In my case, on Windows 10, my JAVA_HOME was set to JAVA SE 16 C:\Program Files\Java\jdk-16 and when I looked at the release file in java jre in android studio, C:\Program Files\Android\Android Studio\jre\release, I found that the the JAVA_VERSION WAS "11.0.10" (java 11) for short. So I changed the java installation on my PC to Java 11, update JAVA_HOME in my environment variables to point to the new java (C:\Program Files\Java\jdk-11.0.12) and restarted android studio, Then everything worked.

You can get your java 11 from here. https://www.oracle.com/java/technologies/javase-jdk11-downloads.html. Change 11 to 8, 16 etc to get the download link for the java version you need.

The problem has to do with having Java 13 or 16 installed on your computer. The current version of Flutter does not work with Java 13 and 16. Just uninstall either of these that you may have installed and installed Java 8 or Java 11. Restart your computer to effect the update. Everything should be fine afterwards

I GOT IT. No need no change your JDK version, follow the steps to resolve the issue:

  • check your java version and remember it, use "java -version" in terminal
  • go to your android studio path installation
  • then in: Android Studio/jre/ open the file named "release"
  • take attention of the value of JAVA_VERSION field
  • if it's not the same as the java version on your computer, just change it with the version installed on your computer.

That's it, i hope it will resolve your issue like it resolve mine.

Try it and give a feedback.

I got this error when using flutter. I fixed it ensuring the android-studio-dir path was set correctly. You set it up using flutter config --android-studio-dir="android studio path". Then run flutter doctor and ensure flutter can see Android Studio

Try to disable AVAST, check system vatiables path for JDK and SDK, clear cache with yarn.
