Could not open settings generic class cache for settings file '

Question

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.

Answer 1

I also had this problem So I did install java 8 You might have Java 13 So install Java 8

Answer 2

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

Answer 3

mainly you have jdk16 i tried to install java 8 and set env to java 8 it worked for me

Answer 4

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

Answer 5

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.

Answer 6

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

Answer 7

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.

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