Flutter：任务“：app：compileDebugKotlin”执行失败

Question

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

Answer 1

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'

Answer 2

通过删除android/.gradle解决了问题，然后在调试中运行应用程序

Answer 3

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

1. flutter clean
2. Delete android/.gradle
3. 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,

1. Go to android/gradle/wrapper/gradle-wrapper.properties
2. 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

Answer 4

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.

Answer 5

in android folder of your project run in terminal

gradlew clean

Then build. This worked for me.

Answer 6

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"
    }
} 

Answer 7

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.

Answer 8

我通过在根build.gradle文件中升级 kotlin 版本来解决它：

ext.kotlin_version = '1.5.10'

Answer 9

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

flutter upgrade

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'

Answer 10

在我通过运行flutter upgrade升级我的Flutter后修复了它

Answer 11

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'

Answer 12

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.

Answer 13

只需将 ext.kotlin.version 从您拥有的任何版本增加到“1.4.32”或任何可用的最新版本kotline 版本

Answer 14

I Update Flutter from 2.10.4 to Flutter 3.0.0 and I found All My Project Has Same Error

ensure that your ext.kotlin_version is '1.6.10'

ext.kotlin_version = '1.6.10'

and run in terminal

flutter pub cache repair

and show that your libraries in pubspec.yamel take last version and run in terminal

1 - flutter clean

2 - flutter pub get

in android studio open File --> invalidate cashes..

this worked for me !!

if this not work for you you may be need to

Delete android/.gradle

thank you .

Answer 18

I encountred the same problem and tried all the solutions proposed here in this post ... and still not working.

Answer 19

For me, my package name imported twice automatically in MainActivity file under app>main>kotlin directory. I just delete duplicates and it works fine now!

Answer 20

在我的情况下更新到最新版本是 1.6.10 或创建虚拟项目并检查 android/build.gradle 并更新。

ext.kotlin_version = '1.6.10'

Answer 21

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 (eg 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.
