Flutter: Execution failed for task ':app:compileDebugKotlin'

I tried running the default flutter app from flutter create on my android device but it throws me an error. Can someone help?

Launching lib\main.dart on SM G610F in debug mode... Running Gradle task 'assembleDebug'...

FAILURE: Build failed with an exception.

What went wrong: Execution failed for task ':app:compileDebugKotlin'.

Could not resolve all artifacts for configuration ':app:debugCompileClasspath'. . . .

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

BUILD FAILED in 14s Finished with error: Gradle task assembleDebug failed with exit code 1

In Flutter 3.27.1 I got the same error while integrating shared_preferences into my project, and the reason is the version of

com.android.application

in android/settings.gradle file

changing from:

id "com.android.application" version "8.1.0" apply false

id "com.android.application" version "8.2.1" apply false

If you are sure it's not an issue with kotlin version or you need a newer version of the Android gradle plugin, then try the following

1.Delete android/.gradle

for macOS users:

sudo rm -r $HOME/.gradle

2- Delete flutter pub-cache

rm -r $HOME/.pub-cache

3- Repair the flutter cache:

flutter pub cache repair

4- get the dependencies and build your flutter app

flutter build apk

Alternatively, delete the dependency that the build is complaining about Then!

1.Get the dependencies without the pub that is causing problems

flutter pub get

2.Fix the cache

flutter pub cache repair

3.Build the app (for android per ex)

 flutter build apk

4.Add again the dependency that was causing problems 5.Get the dependencies

flutter pub get

You are all set!

Go to your build.gradle file in the root of your Android directory and upgrade your Kotlin_version to the latest. As of the time of typing this, the latest is 1.5.10, so it should look like this:

ext.kotlin_version = '1.5.10'

You can find the latest Kotlin version here.

Please verify your existing Kotlin version. If you're working with Android Studio, you can do this by navigating to Tools -> Kotlin -> Configure Kotlin Plugin Updates. Once you've identified the current version, proceed to the android/build.gradle file and update the ext.kotlin_version to match that version.

In my case, I had to set the JavaVersion according to the Kotlin version.

So to fix this error:

'compileDebugJavaWithJavac' task (current target is 1.7) and 'compileDebugKotlin' task (current target is 17)

I had to set this values in the file build.gradle:

compileOptions {
    sourceCompatibility JavaVersion.VERSION_17
    targetCompatibility JavaVersion.VERSION_17
}

In our case, the package flutter_appcenter_bundle caused this issue.

To fix it, you need to run flutter precache.

This needs to be done only once and it will be effective as long as the Flutter version remains unchanged and the precached artifacts are not deleted (e.g. by deleting the Flutter root folder).

Also, the environment variable FLUTTER_ROOT needs to be set to the Flutter root folder. On Windows it's usually C:\src\flutter.

If you use AndroidStudio, you can do that in Settings > Languages & Frameworks > Flutter.

If you don't use AndroidStudio, you need to set FLUTTER_ROOT manually.

First of make sure that you have latest version of flutter. For confirmation, please run flutter upgrade in command prompt / terminal:

Then visit the site Click Here and copy the new latest version of kotlin. For now: in March 02, 2022 current kotlin version is 1.6.10

Then after it:

-> Go to android/build.gradle
-> change to ext.kotlin_version = '1.6.10'

It was fixed after I upgraded my build.gradle file ext.kotlin_version = '1.5.10'

First of all run

flutter clean
flutter pub get

Go to andriod/build.gradle then upgrade ext.kotlin_version

buildscript {
    ext.kotlin_version = '1.5.10'
    repositories {
        google()
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:4.1.0'
        classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    }
}

A possible fix can be upgrading the project/android/build.gradle Steps to fix,

flutter clean
Delete android/.gradle
Go to android/build.gradle, upgrade ext.kotlin_version to latest. In my case(1.3.0 -> 1.5.10), ext.kotlin_version = '1.5.10'

After doing this as well, I was getting `A problem occurred evaluating project ':app'.

Failed to apply plugin [id 'kotlin-android'] The current Gradle version 5.6.2 is not compatible with the Kotlin Gradle plugin. Please use Gradle 6.1 or newer, or the previous version of the Kotlin plugin.`

To fix this,

Go to android/gradle/wrapper/gradle-wrapper.properties
Update the distributionUrl to the latest version.In my case((5.6.2 -> 6.1.1) it is, distributionUrl=https\://services.gradle.org/distributions/gradle-6.1.1-all.zip

I got the problem after migrating to null-safety. I fixed it by updating the kotlin version in the file android\build.gradle

ext.kotlin_version = '1.3.50'

Then run 'flutter clean' and the app worked fine.

I have been facing this issue for couple of hours. At the end right now my issue solved by executing following steps -

- change Settings -> Build, Execution, Development -> Compiler -> Kotlin Compiler -> Kotlin to JVM -> check Enable incremental comilation -> Target JVM version 1.6 to 1.8

- add to build.gradle under repositories in both buildscript and allprojects section

maven {
        url 'http://download.flutter.io'
    }

-and lastly run on command line 'flutter pub cache repair'

For me, I found that when building that 2 different MainActivity.kt files were in andriod/app/src/main/kotlin. One had a default MainActivity.kt file with the package name that was originally generated for my project. Something like 'example.project_name' . The other one had what I changed my project name into. I went ahead and deleted the folder with the MainActivity.kt containing the import starting with 'example.project_name' and that resolved the issue for me.

I solved it. It was because of my network blocked non secured http download request. I changed my network and the gradle build completed itself.
