Exception: Gradle task assembleDebug failed with exit code 1
I recently Solved this problem.
This Problem came from gradle file is corrupted in my system.
I'm using Linux so this steps almost same in windows also. This answer is for any gradle version.
Open File Manager:
enable Show hidden folder from top menu bar.
You may find this location : .gradle>wrapper>dists.
In Linux: Home > .gradle > wrapper > dists.
In Windows: C:>Users>{PC Name}>.gradle>wrapper>dists
Method 1
Go inside gradle-6.5-all > dists > 2oz4ud9k3tuxjg84bbf55q0tn. '2oz4ud9k3tuxjg84bbf55q0tn' may be different in your PC.
Delete all files in that folder and download required file manually: https://downloads.gradle-dn.com/distributions/gradle-6.5-all.zip
after download paste freshly downloaded zip file in that folder.
Run your project flutter run -v
Method 2
Try this if you have fast & stable internet connection.
Delete that gradle-6.5-all folder.
Open project in VS code or Android Studio and open terminal.
Run this command flutter run -v
Method 3
Flutter Doctor will give right result.
Open Android Studio
Create new flutter project
Click on Tools > flutter >Flutter for editing in android studio
and wait, flutter doctor takes time to identify problem.
Use this link for download gradle file.
Replace 6.5 with your gradle version.
https://downloads.gradle-dn.com/distributions/gradle-6.5-all.zip
I hope this answer helpful for you.
Please use the below command
1.Mac User :
rm -rf ~/.gradle
2.Windows User :
remove the .gradle file
.gradle file location -> C:\Users\myUser
I solve this error by updating the gradle plugin/version. I have as part of my configuration:
Windows 10
Android Studio 4.2.1
Java 11: Android Studio 4.2.1 don't have support for JDK 16, so, I installed JDK 11, and configured the AS (how to change the jdk in AS) to use this older JDK
Gradle 7.0.1
By default, when you create a new Flutter project, the IDE created it with basic standard configurations, so you have to change this configs to fit your current config. For that, you need to update the gradle config in the flutter project, as follow:
in android/gradle/build.gradle file: update the gradle plugin to 4.2.0 in the dependencies section, like this:
dependencies {
classpath 'com.android.tools.build:gradle:4.2.0'
//more dependencies
}
in android/gradle/wrapper/gradle-wrapper.properties file: update the gradle version, in this case I have the 7.0.1, feel free to use another one, like this
distributionUrl=https\://services.gradle.org/distributions/gradle-7.0.1-all.zip
//more attributes
After you change the gradle config, run this commands in your project:
flutter clean : clean the project
flutter pub get : update your dependencies
flutter run : run the project. Now it must work, at least it work for me
I faced the same problem in VSCode when I wanted to run the Flutter app I got that error, so after lots of debugging and research, I found the solution. it's pretty easy, just follow these steps:
In windows 10:
1. Open flutter project in a Text-Editor like VSCode.
2. Open android -> gradle -> wrapper -> gradle-wrapper.properties
3. You will find "gradle-6.7.1.all.zip" inside gradle-wrapper folder
4. Go to this path: C:\Users\your-user
5. Then go to the wrapper->dists and find "gradle-6.7.1.all" folder
5. Delete this folder.
6. Then come to VSCode and open Terminal.
7. Please make sure that you have stable internet connection then type this command in terminal
8. flutter run
I hope this solution can help you!
I solve this error by deleting the .gradle folder.
This location is gradle folder
In Windows: C:> Users> {PC Name}>. Gradle
After deleting this folder, you only need to run the application again in Android Studio. At this point, Android Studio starts downloading the deleted folder automatically.
enter image description here
This error is caused by corrupted gradle files, this is either due to incomplete downloads due to network issues. To solve it easily download the gradle zipped file from https://downloads.gradle-dn.com/distributions/gradle-6.7-all.zip and paste on the .gradle directory as shown below if you are on linux
enter image description here
I try all method but it did not work for me so i decided to location the gradle-wrapper.properties in the andriod folder then i change the distribution gradle link to a more recent gradle link.
Welcome SO.
Java 16/latest version is not fully compatible with the Gradle 6 at this moment. Try to use java 11 or 8, it will resolve your issue.
i have ran flutter pub get multiple times but I'm still not able to download the carousel_slider package
So far I've tried:
Running flutter clean
Running flutter packages get
Running flutter packages get
Restarting my computer
Updated flutter
Tried opening it in VSCode instead
Added another package (but that did install, I could see it in the Dart Packages)
I see that is working well, but you can try deleting the pubspect.lock
In the terminal write this commands:
flutter clean
flutter packages get
I create new app in flutter and it's work when I run it, but when I add shared_preferences package, I got this error when I run it
Could not determine the dependencies of task ':url_launcher:compileDebugAidl'.
Could not resolve all task dependencies for configuration ':url_launcher:debugCompileClasspath'.
Could not resolve project :url_launcher_macos.
Required by:
project :url_launcher
Unable to find a matching configuration of project :url_launcher_macos:
- None of the consumable configurations have attributes.
Neither package is compatible with mac
I have faced the same problem and i have fixed this with running following command:
flutter pub cache repair
If this is not working then please try the following:
flutter channel stable then run the commands
flutter clean and flutter upgrade
This worked for me
NOTE:- CLOSE THE FLUTTER PROJECT
Go to Flutter sdk path
Enable the view hidden files in Mac by using CTRL + SHIFT + .
Go to .pub-cache
Go to hosted
Go to pub.dartlang.org
delete this folder url_launcher_macos
Open the project and run app
i just setup my android studio and vs code and flutter SDK installed but any time i try running the project i get this Gradle error, i cant figure out what the problem is please help me out.
After running the flutter doctor everything seems to be okay.
the problem might be caused by many factors so lets try some solutions
after each one rebuild your app if the error message changed or the problem solved please keep us informed
run these commands one by one
flutter channel stable
flutter upgrade --force
flutter pub cache repair
cd your app folder
flutter clean
edit app/build.gradle in your host app such as it includes the local repo
like in here
repositories {
maven {
url 'https://storage.googleapis.com/download.flutter.io'
}
}
use VPN and rebuild your app
After installing flutter and running my emulator it stops at initializing gradle on android studio and on vs code.
It outputs:
this is taking an unexpectedly long time.
I ran flutter doctor and no issues and also flutter doctor -v and still no issues. I tried flutter upgrade but still no difference.
What is the next thing to try?
flutter error log
It looks like it is just taking forever to start; You can read the thread on the issue on
Github:
To summaries: here is one of the issues: Downloading 400mb of dependencies
Solved Initializing gradle problem
The problem is that when first time we are trying to run our flutter
project it does not have the required flutter gradle file. The
required file size that gradle downloads is about 300-400MB that's why
it takes so much time. Following are the steps:
Run your project by clicking on the 'Run' button or flutter run in the command terminal
Then go to the place where your .gradle file is located (usually it is in the C:\Users). In the .gradle folder there is file
name as wrapper in this there is dists folder. In dists folder there
is gradle folder which is being downloaded.
wait till the gradle file is being downloaded and after sometime your project would compile.
its working thaaaaaanks
I am new to mobile development; Everything takes eternity.
Solved this issue by removing all the gradle files from
C:\Users\.gradle\wrapper\dists
Now when you run your flutter app, it will automatically download the required gradle files.
Enjoy!!!
