This is my gradle file:

apply plugin: 'com.android.application'

    android {
        compileSdkVersion 27
        buildToolsVersion "27.0.1"
        defaultConfig {
            applicationId "com.landdrops.cricketfantacy.androidbottom"
            minSdkVersion 21
            targetSdkVersion 27
            versionCode 1
            versionName "1.0"
            testInstrumentationRunner "android.support.test.runner.AndroidJUnitRunner"
        }
        buildTypes {
            release {
                minifyEnabled false
                proguardFiles getDefaultProguardFile('proguard android.txt'), 'proguard-rules.pro'
            }
        }
    }

    dependencies {
        implementation fileTree(include: ['*.jar'], dir: 'libs')
        implementation 'com.android.support:appcompat-v7:27.0.1'
        implementation 'com.android.support:design:27.0.1'
        implementation 'com.android.support.constraint:constraint-layout:1.0.2'
        testImplementation 'junit:junit:4.12'
        androidTestImplementation 'com.android.support.test.runner:1.0.2'
        androidTestImplementation 'com.android.support.test.espresso:espresso-core:2.2.2'
    }

I am getting

Error:(23, 0) Could not find method implementation() for arguments [directory 'libs'] on object of type org.gradle.api.internal.artifacts.dsl.dependencies.DefaultDependencyHandler. Open File

For my Java library project I needed to use java-library plugin instead of java:

- apply plugin: 'java'
+ apply plugin: 'java-library'
