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.

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).

So the problem arises from inconsistency in the Java version installed on your machine, the default Java version configured on your android studio and the gradle version for your project. So building upon the answer given by Tafita Raza I fixed it following the steps below

Check your java version and remember it, use "java -version" in terminal
Go to your android studio path installation
In newer versions of android studio go to Andriod Studio/jbe while in older versions go to Android Studio/jre/ and edit the file named "release"
Replace the value of JAVA_VERSION with the version of Java installed on your machine if it's not the same as the java version on your computer
Now go into the project folder you are building and check if the Gradle version is compatible with the Java you have installed (latest table below, as of 2023-11-12)

Java version	Support for compiling/testing/…	Support for running Gradle
8	N/A	2.0
9	N/A	4.3
10	N/A	4.7
11	N/A	5.0
12	N/A	5.4
13	N/A	6.0
14	N/A	6.3
15	6.7	6.7
16	7.0	7.0
17	7.3	7.3
18	7.5	7.5
19	7.6	7.6
20	8.1	8.3
21	8.4	8.5

I had java 19.0.2 installed on my system so according to the table I need gradle version 7.6 to build a project. You can also check the official website gradle if your java version is not listed https://docs.gradle.org/current/userguide/compatibility.html
Go into your project_name/android/gradle/wrapper and edit the file gradle-wrapper.properties
Replace the distributionUrl with the version of gradle compatible with the java version on your system

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

FOUND IT ! No need to 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 resolves mine.

Try it and give a feedback.

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

gradle-7.4 for JDK 17

gopelkujo Over a year ago

in my experience exploring this problem, if you upgrade jdk then you need to upgrade the gradle version too like this answer. But, you need to upgrade Android Gradle Plugin (AGP) too and that's where i stuck. Because, idk why server can't find AGP that compatible with gradel version. Everytime i search for the problem most answer is incompatible version of java, gradle, and agp. In the end i just back to old version.

In gradle wrapper.properties, change the code to this -

distribution Url = https://services.gradle.org/distributions/gradle-7.2-all.zip

In build.gradle, change the code to this -

classpath "com.android.tools.build:gradle:7.1.3"

And then, hit flutter run in terminal

Wait for the gradlew finish the build process

Simply go to your Android Studio path -> C:\Program Files\Android\Android Studio open jbr folder -> copy all files -> then go back -> paste all the files in the jre folder and "replace the files in the destination". It works for me in two different laptops. I have latest jdk version - 19.0.2

All you have to do is change the java version to 11 and provide JAVA_HOME to jdk 11. You need to ensure to delete any other java versions (latest). Then restart the system and it will work.

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.

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

The error message you're seeing is related to the flutter build process and it occurs when a required input or output annotation is missing from the assets property of the FlutterTask.

task buildFlutter(type: FlutterTask) {
// Add the @Input annotation to the assets property
@Input List<String> assets = ["assets/images/", "assets/fonts/"]

In my recents projects, I use:

sudo update-alternatives --set java /usr/lib/jvm/java-17-openjdk-amd64/bin/java

for example, I created alias to change between

I could not comment and thank @joseph-deweese and @tafita-raza due to less contribution but all credits to them.

Basically what i did was , I did not have /jre folder in /Android Studio , so created a new folder copied everything from /jbr folder and in the release file i updated the java version from 21 to 23 which I had installed in mine (check yours with java --version in terminal and replace)

Now add environment variable JAVA_HOME to this path i.e. C:\Program Files\Android\Android Studio\jre for me I think /jbr would also work but I am not touching my config again till the next error

EDIT - Better use Java 17 as of now
