}

Please help to solve the issue

Answer 1

Replace implementation with compile.

compile was recently deprecated and replaced by implementation or api

Answer 2

Make sure your Gradle version is 3.*.* or higher before using "implementation".

Open the project level Gradle file under dependencies:

dependencies{
    classpath 'com.android.tools.build:gradle:3.1.2'
}

Open the 'gradle-wrapper.properties' file and set the distributionUrl:

distributionUrl=https\://services.gradle.org/distributions/gradle-4.4-all.zip

or latest version.

Sync the project. I Hope this solves your problem.

Answer 3

Make sure you're adding these dependencies in android/app/build.gradle, not android/build.gradle

Answer 4

You need to use at least Gradle 3.4 or newer to be able to use implementation. It is not recommended to keep using the deprecated compile since this can result in slower build times. For more details see the official android developer guide:

When your module configures an implementation dependency, it's letting Gradle know that the module does not want to leak the dependency to other modules at compile time. That is, the dependency is available to other modules only at runtime. Using this dependency configuration instead of api or compile can result in significant build time improvements because it reduces the amount of projects that the build system needs to recompile. For example, if an implementation dependency changes its API, Gradle recompiles only that dependency and the modules that directly depend on it. Most app and test modules should use this configuration.

https://developer.android.com/studio/build/gradle-plugin-3-0-0-migration.html#new_configurations

Update: compile will be removed by end of 2018, so make sure that you use only implementation now:

Warning:Configuration 'compile' is obsolete and has been replaced with 'implementation'. It will be removed at the end of 2018

Answer 5

change apply plugin: 'java' to apply plugin: 'java-library'

java-library-plugin

Answer 6

So ridiculous, but I still wanna share my experience in case of that someone falls into the situation like me.

Please check if you changed: compileSdkVersion --> implementationSdkVersion by mistake

Answer 7

For me I put my dependencies in the wrong spot.

buildscript {
  dependencies {
    //Don't put dependencies here.
  }
}

dependencies {
 //Put them here
}

Answer 8

Your Code

dependencies {
    compile fileTree(include: ['*.jar'], dir: 'libs')

Replace it By

dependencies {
implementation fileTree(include: ['*.jar'], dir: 'libs')

Answer 9

As mentioned here, https://stackoverflow.com/a/50941562/2186220, use gradle plugin version 3 or higher while using 'implementation'.

Also, use the google() repository in buildscript.

buildscript {
    repositories {
        google()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:3.1.2'
    }
}

These changes should solve the issue.

Answer 10

Replace your implementation with classpath. That should work.

Answer 11

I moved implementation to module-level build.gradle from root-level build.gradle. It solves the issue.

Answer 12

In my case it was because I used Implementation instead of implementation.

Answer 13

If implementation is not defined, you are writing on a wrong file. On Unity 2019+ the correct file is main template grandle and not some of the others.

Answer 14

As suggested in official docs you need add these :

buildscript {
    repositories {
        // Gradle 4.1 and higher include support for Google's Maven repo using
        // the google() method. And you need to include this repo to download
        // Android Gradle plugin 3.0.0 or higher.
        google()
        ...
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:4.2.0'
    }
}

adding these remove my error. Also use implementation instead of compile.
