Answer 1

To use the DSL implementation() you have to use:

• The updated gradle plugin for Android 3.0.0
• The gradle version 3.4 or later

Then in your build.gradle you have to use:

buildscript {
    repositories {
        ...
        // You need to add the following repository to download the
        // new plugin.
        google()
    }

    dependencies {
        classpath 'com.android.tools.build:gradle:3.0.0-beta1'
    }
}

In your gradle-wrapper.properties

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

In my case it was just a typo. It was an extra sign "/" after one of rows

Answer 3

I ran into similar errors. when I tried to include the recyclerview dependencies from may build.gradle(Module: app) with a code like so.

//other build.gradle(Module: App) code above
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.3.1'
    compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha7'
    testCompile 'junit:junit:4.12'
    implementation 'com.android.support:recyclerview-v7:25.3.1'
}

So the simple way I fixed this is by changing the code to this, where I changed the implement to compile while retaining every other code and their version numbers.

//other build.gradle(Module: App) code above
dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    androidTestCompile('com.android.support.test.espresso:espresso-core:2.2.2', {
        exclude group: 'com.android.support', module: 'support-annotations'
    })
    compile 'com.android.support:appcompat-v7:25.3.1'
    compile 'com.android.support.constraint:constraint-layout:1.0.0-alpha7'
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:recyclerview-v7:25.3.1'
}

I hope this helps some one having similar issues. PS: The actual error was caused by implementation 'com.android.support:recyclerview-v7:25.3.1' and changing the code to compile 'com.android.support:recyclerview-v7:25.3.1' got it fixed.
