Hi @Mirshodbek @devchenli
I can reproduce the issue, it occurs during gradlew command so I am not sure if it is related to Flutter itself.

A solution suggested was to use build tools 30.0.3 but still persist, labelling for gradle

What are the steps to reproduce this issue?

I can reproduce this in the GitJournal project.

Hixie · 2021-11-11T00:09:46Z

It may not be caused by Flutter itself, but we should still figure out what's causing it and stop it, since it's clearly not useful to our users.

talamaska · 2021-11-24T22:07:05Z

It is some discrepancies in the gradle versions. I have tested with the codelab https://github.com/googlecodelabs/admob-inline-ads-in-flutter.
There was some toaster from AS that the project gradle version could be updated.
I have set distributionUrl=https://services.gradle.org/distributions/gradle-7.0.2-bin.zip in gradle-wrapper.properties and
classpath 'com.android.tools.build:gradle:7.0.3' in android/build.gradle and the warnings disappeared.

talamaska · 2021-11-28T19:31:34Z

Interestingly enough, I have a package, that on one machine is not throwing any warnings. On another, after an AS and SDK reinstall started throwing these warning. I have the same sdks, build tools, ndks and emulators. I cleaned build cache and cache in the ~/.android folder and the wrappers, cache and daemon folders from ~/.gradle folder, same thing. I have android sdk from 26 to 30 and the build-tools installed are 26.0.2, 28.0.3, 29.0.2, 30.0.2 and 31.0.0. The ndk's are 21.1.6352462 and 23.0.7599858. The project is setup with
distributionUrl=https://services.gradle.org/distributions/gradle-6.7-all.zip
and classpath 'com.android.tools.build:gradle:4.1.0'

I'm building for emulator 29 and compileSdkVersion and targetSdkVersion is 29
Also because I know that the .idea folder is in .gitignore, I even copied manually the whole project from one machine to another with a usb drive without any success.
I'm trying to provide as much information I have in order to help finding what's the issue.
Sure it's just a warning, but it's pretty annoying because I don't know how to resolve it. Is it safe to update gradle versions all to 7.x like in my previous comment? I'm not sure about this because I saw some messages from gradle that in the scripts were used some deprecated stuff. I'm not an Android developer. Please help.

lfernando43 · 2022-01-02T23:20:08Z

gradle:7.0.3

It worked for me too!
Thanks for the advice...

lfernando43 · 2022-01-02T23:21:51Z

set distributionUrl=https://services.gradle.org/distributions/gradle-7.0.2-bin.zip in gradle-wrapper.properties and
classpath 'com.android.tools.build:gradle:7.0.3' in android/build.gradle

cpin-fortinet · 2022-01-03T19:28:38Z

This solves the issue for me:
https://stackoverflow.com/a/70570495/17825313

Basically just use the latest gradle plugin and gradle version of the AndroidStudio and make sure they both match according to the official doc.

To solve this issue, you have to make sure your gradle in your build.gradle and the gradle in your android/gradle/wrapper/gradle-wrapper.properties are the same version. even if they are not the latest version, it must be the tally with each other like this:

distributionUrl=https://services.gradle.org/distributions/gradle-7.3-all.zip

emphasis on the gradle-7.3

and

android/build.gradle

buildscript {
repositories {

dependencies {
classpath 'com.android.tools.build:gradle:7.0.0'
