I have already done：

Same here. This is fixed in master but not under stable release yet. For now, I would suggest switching to master branch and wait for the fix to be released.

same issue

[Parth1029]

I solved the problem by moving :

maven {
    url 'https://dl.google.com/dl/android/maven2'
}

in the top of:

jcenter()

in the file: .flutter/packages/flutter_tools/gradle/flutter.gradle :

    buildscript {
    repositories {
        maven {
            url 'https://dl.google.com/dl/android/maven2'
        }
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
    }
}

[sumation]

same issue
Solved by adding "google()" to gradle

[songyiYu]

@Parth1029 It is solved! Thank you 👍

[Sly777]

@Parth1029 thanks it works on my app as well!

[rravithejareddy]

still i am facing the issue.

[xring]

@ Parth1029 Great work! Thx.

[rravithejareddy]

@Parth1029 still i am facing the issue, i tried to adding google(), but still i am getting same issue.

[marianoarga]

Upgrading Flutter should fix it @rravithejareddy

[rravithejareddy]

Fixed by adding google() in flutter.gradle. Thanks.

[yefeidd]

I solved the problem.
File->setting->build->Gradle->Android studio
checked "Enable embedded Maven repository".

[ethanyou725]

gradle.properties set proxy

[TakeEasyBoy]

I solved the problem.In android folder,edit build.gradle file like this:

buildscript {
    repositories {
        google()
        mavenCentral()  //add this line
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
    }
}

It works.

I had the same problem :

Could not resolve all artifacts for configuration ':classpath'.
Could not find builder.jar (com.android.tools.build:builder:3.0.1)
...... (62 error line)

The problem occurred when I was trying to add a package to my pubspec.yaml (audioplayers) so if you have the same problem, in Android Studio, at the left side (Project View (alt +1) navigate to:
External Libraries > Flutter Plugins > audioplayer (you should go to your plugin) > android > build.gradle
and change classpath 'com.android.tools.build:gradle:OLD VERSION' to YOUR VERSION. For example that was 3.0.1 which I needed 3.3.0

[shaileshpanthee]

I solved the problem by moving :

maven {
    url 'https://dl.google.com/dl/android/maven2'
}

in the top of:

jcenter()

in the file: .flutter/packages/flutter_tools/gradle/flutter.gradle :

    buildscript {
    repositories {
        maven {
            url 'https://dl.google.com/dl/android/maven2'
        }
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
    }
}

I couldn't find the file .flutter. Where is the .flutter dir located?

[coderoid-omega]

I solved the problem.In android folder,edit build.gradle file like this:

buildscript {
    repositories {
        google()
        mavenCentral()  //add this line
        jcenter()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.2.1'
    }
}

It works.

It Worked!

[coderoid-omega]

I solved the problem by moving :

I couldn't find the file .flutter. Where is the .flutter dir located?

.flutter is just a convention, here '.flutter' is the path where you extracted or installed flutter in your system. Hope this helps you.

[Niek-Okido]

edit the following in build.gradle :

    repositories {
        jcenter()
        mavenCentral() #add

    ....

i Dont know why am getting this error......

THIS IS MY build.gradle
pls i dont know what to do

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {

[derekgithubs]

I solved it by....

• go to search icon on the top-right corner and search for "Execute Gradle Task".
• click on result "Execute Gradle Task" after it appear , And you'll be given sort of options.
  NOTE: Now make sure you have internet.
• double click on "gradle mergeDexRelease" among the other options.
  .....Now wait for it to finish download some stuffs, then you are good......

It worked for me, i'm using Windows...

[nhhockeyplayer]

this is outrageous
the whole subsystem, surrounding gradle needs to be torn out honked and redesigned and replaced
I have never seen such lengthy issues on incomplete gradle mechanisms
and they still havent gotten it right
i spent days/weeks June 2019 on same gradle wrapper transient dependencies omissions and now its impact8in my development schedule again

WHEN WILL THEY FINALLY DESIGN SOMETHING THATS CONFIGURABLE FROM THE ROOT FILE CONFIG.XML AND BE DONE WITH IT... environment variables anyone ?

I know if Im going to shoot my mouth off I should do it myself

well its simple

a root environment variable that trickles down thru the whole archetype

DONE

and maybe a flag for caching to prevent tangled repo jars

[Sylvester-dev]

@gayanramyakumara I am also facing same issue can i know how you solved this issue.

[nhhockeyplayer]

i went with capacitor
instead of treating the android like a build artifact it treats it as a source artifact
completely configurable
