Must supply one of aapt2 from maven or custom location

Question

I am trying to run my flutter app but I got some error.

 FAILURE: Build failed with an exception.

    * What went wrong:
    Execution failed for task ':app:mergeDebugResources'.
    > Specified AAPT2 executable does not exist: C:\Users\john\.gradle\caches\transforms-2\files-2.1\a406eb4ba72ff395bc6c8b1db90b3b1f\aapt2-3.5.0-5435860-windows\aapt2.exe. 
    Must supply one of aapt2 from maven or custom location.
        
    * Try:
    Run with --stacktrace option to get the stack trace. Run with --info or --debug option to get more log output. Run with --scan to get full insights.
    
    * Get more help at https://help.gradle.org

This is my buildscript

buildscript {
    ext.kotlin_version = '1.3.50'
    repositories {
        google()
        jcenter()
        
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.5.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

Last time I can run my flutter app but now I don't know what happened. I hope you can help me. TIA

What version of Android Studio are you using? You should be on AS 4.0 with a corresponding Android Gradle Plugin version (4.0) — Ovidiu, Jul 22 '20 at 09:16
Delete the .gradle file, Android Studio should create it again — user3425867, Jul 25 '20 at 15:16

I just found the solution to my problem.

I changed the dependencies classpath in my buildsript

dependencies {
    classpath 'com.android.tools.build:gradle:3.5.0'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}

Into

dependencies {
    classpath 'com.android.tools.build:gradle:3.5.3'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
}

Now it's working!

Try running flutter clean on Android Studio's terminal or just selecting the option on the Flutter menu at the top:

If this doesn't work, take a look at this question: How to solve Specified AAPT2 executable does not exist on Android Studio 3.2

Could you create a new project from scratch, copy your code there and try to rebuild it? – Michel Feinstein Jul 28 '20 at 23:05
I already did that. I also create new flutter project but still having the same problem – CodeFloat Jul 29 '20 at 02:10
Have you copied just the code? Can you compile a simple counter demo? – Michel Feinstein Jul 29 '20 at 02:25
