Gradle error Android Studio

Question

I'm trying to build a project but it keeps giving me this gradle error I have upgraded my gradle 3.3 and my android plugin version to 2.3.3 but it's still giving me error Any help would be appreciated Error:

Error:(40, 0) Gradle DSL method not found: 'implementation()' Possible causes:

The project 'sms-mining-android' may be using a version of the Android Gradle plug-in that does not contain the method (eg 'testCompile' was added in 1.1.0). Upgrade plugin to version 2.3.3 and sync project

The project 'sms-mining-android' may be using a version of Gradle that does not contain the method. Open Gradle wrapper file

The build file may be missing a Gradle plugin. Apply Gradle plugin

Event Log: Gradle sync failed: Could not find method implementation() for arguments [com.android.support.constraint:constraint-layout:1.0.2] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler.

Answer 1

try this gradle configuration ,it works for me :

buildscript {
ext.kotlin_version = '1.1.2-5'
ext.support_lib_version = '25.3.1'
ext.junit_version = '4.12'
ext.constraint_layout_version = '1.0.2'
ext.rxjava_version = '1.1.3'
ext.rxandroid_version = '1.1.0'
ext.mpchart_version = 'v3.0.2'
ext.realm_version = '3.3.2'
repositories {
    jcenter()
    maven { url 'https://maven.google.com' }
}
dependencies {
    classpath 'com.android.tools.build:gradle:3.0.0-alpha4'
    classpath "org.jetbrains.kotlin:kotlin-gradle-plugin:$kotlin_version"
    classpath "io.realm:realm-gradle-plugin:$realm_version"

    // NOTE: Do not place your application dependencies here; they belong
    // in the individual module build.gradle files
}

}

allprojects {
repositories {
    jcenter()
    maven {
        url "https://maven.google.com"
    }
    maven { url "https://jitpack.io" }
}

}

task clean(type: Delete) {
delete rootProject.buildDir

}

add maven { url 'https://maven.google.com' } in repositories

And use Android studio 3.0 preview for this configuration.

Answer 2

simply add this into your project level gradle

classpath 'com.android.tools.build:gradle:3.0.0-alpha4'

it is because you have implementation() method in your app level gradle file

Answer 3

This is an answer tested and works on Android Studio 3.0 Canary 6.

Upgrade gradle version in your project level gradle classpath to a more recent one.

Of what I understand regarding the official documentation about gradle / gradle plugin version compatibility it should work with gradle plugin version 2.3.3 and gradle version 3.3 (anybody correct me if I'm wrong):

Anyway I had to upgrade the plugin to version 3.0.0-alpha6 to get rid of the error. To do so make this change in project level build.gradle :

dependencies {
    ...
    classpath 'com.android.tools.build:gradle:3.0.0-alpha6'

Note I had a different gradle version than yours in my gradle-wrapper.properties (4.1):

distributionUrl=https\://services.gradle.org/distributions/gradle-4.1-milestone-1-all.zip

So if you change these both lines in these both files it should works. Note that com.android.tools.build:gradle:3.0.0-alpha4 suggested by @Narendra kumawat didn't work for me, I had to use alpha6.
